Microsoft Retires Mobile Plans App, Shifting Windows eSIM Provisioning to Settings

ChatGPT · Aug 29, 2025

Microsoft will retire the long-underused Mobile Plans app from Windows and move plan purchases and eSIM provisioning to carrier websites and the built‑in Windows Settings experience, with the in‑OS app scheduled to stop functioning on February 27, 2026; installed cellular profiles will continue to work, but discovery, checkout, and subscription management will shift to operators and Settings-driven provisioning.

Background / Overview

The Mobile Plans app has existed since the Windows 10 era as a small, targeted gateway for cellular‑equipped PCs to discover carriers, purchase data plans, and install eSIM profiles or activate physical SIMs. It offered a single, consistent in‑OS funnel: detect a cellular radio, list participating operators, open an operator checkout, and receive provisioning (commonly by pushing an eSIM profile to the PC). That funnel was intended to lower friction for always‑connected laptops and tablets by giving users a uniform discovery-to-provisioning journey.
Microsoft’s announced change eliminates that dedicated storefront and delegates the buying experience to carriers’ web portals. The OS will continue to host the provisioning capability: Settings > Network & Internet > Cellular retains the eSIM and cellular management surface, and a new Settings‑prompt model will mediate sharing device identifiers with carriers to enable automatic provisioning where supported. Microsoft expects the Settings‑mediated identifier sharing feature to be available before the end of 2025 and has set the Mobile Plans app retirement date for February 27, 2026; however, some details of the public‑facing schedule and partner participation remain subject to confirmation by Microsoft and participating carriers.

What the Mobile Plans app did — a technical recap

The app provided a unified UI to:
Discover participating mobile operators from a small catalog.
Open operator portals for plan sign‑up or to add a PC to an existing account.
Deliver eSIM provisioning and in‑OS plan visibility (status, remaining data).
It supported both eSIMs (embedded SIM profiles) and classic physical SIM activation workflows.
In some operator integrations, notifications or operator‑triggered messages routed users into the Mobile Plans experience for offers or renewals.

The app’s existence was never about core radio drivers or cellular stacks; those remain part of Windows. Mobile Plans was a convenience layer that simplified how users found and purchased data plans from within the operating system.

Why Microsoft is retiring Mobile Plans

Microsoft’s stated rationale is pragmatic consolidation:

Reduce maintenance surface: The Mobile Plans app serves a small slice of Windows users (cellular‑equipped machines). Removing an in‑OS storefront reduces engineering, testing, and update overhead.
Give carriers full commerce control: Carriers prefer to own checkout, SKU management, promotions, refunds and identity verification. Web portals permit richer, faster iteration than a constrained in‑OS funnel.
Leverage existing Settings provisioning: Windows already supports eSIM profile installation and can mediate device identifier consent for automatic provisioning. A Settings‑driven flow can replace the bespoke app while keeping provisioning native to Windows.

This move follows a broader pattern of folding low‑demand, specialized UWP features into web experiences or core OS Settings surfaces.

Timeline and what’s verifiable today

The operational end date for the Mobile Plans app has been reported as February 27, 2026. Microsoft will remove the app from the Microsoft Store and stop linking to it from documentation after that date.
Microsoft expects the Settings‑mediated device‑identifier sharing (to allow automatic eSIM provisioning when you purchase on a carrier site) to be released before the end of 2025.
Microsoft’s core eSIM and cellular management functionality remains in Settings now; existing eSIM profiles already installed on devices will continue to function after the app’s retirement.

Caveat: while multiple industry reports and platform guidance reference the dates and the new Settings-forward flow, exact corporate communications (for example, a single, consolidated public retirement bulletin on Microsoft’s Tech Community) may be distributed through partner and enterprise message channels. For organizations planning deployments, confirm schedule details through official Microsoft admin/Message Center notices as well as with carrier partners.

How the new provisioning flow will work (high level)

User visits a carrier’s website to purchase a plan or add a device to an account.
The carrier checkout asks the user to choose a device (or detects it via browser metadata) and — with the user’s explicit consent — triggers Windows Settings to request permission to share device cellular identifiers (for example, EID and IMEI).
If consent is granted, the identifiers are securely passed to the operator to automatically provision an eSIM profile to the device without the need to scan a QR code or manually enter activation codes.
If the carrier does not support automatic Settings‑triggered provisioning, standard alternatives remain: QR codes, activation codes, or manual provisioning via carrier instructions.

Key technical points:

eSIM provisioning in Windows can occur via QR image scans, activation codes, or web‑triggered provisioning when the OS and carrier support it.
The identifiers commonly referenced include the device’s EID (eUICC identifier for eSIM) and IMEI (device mobile equipment identifier). Consent to share these must be mediated by the OS.
Settings will be the place to accept identifier sharing and to complete the eSIM install; it is not an entirely web‑only handoff.

Carrier readiness and ecosystem responsibilities

Shifting “buy + provision” to carrier web portals places heavy responsibility on operators. Practical requirements for carriers to make the transition smooth:

Publish a clear, Windows‑specific activation and support page that:
Explains how to activate plans on Windows PCs.
Provides both automatic Settings‑triggered provisioning and fallback QR/activation code flows.
Is desktop‑friendly (not mobile-only) and handles desktop user agents gracefully.
Implement or extend server‑side provisioning backends to accept device identifiers (EID/IMEI) and push eSIM profiles to Windows devices securely.
Clarify privacy, retention and consent policies for device identifiers so users know what carriers collect, how long they keep it, and how to revoke consent.
Offer a robust fallback support channel — single‑use QR codes, activation keys, or short support paths for desktop users — because not every user or carrier will support the Settings‑triggered seamless path on day one.

Carriers that invest in desktop-first checkout and tested provisioning will retain lower friction onboarding for Windows customers; others risk increased helpdesk load and churn.

OEM and enterprise implications

OEMs

OEMs can continue to include carrier information and activation links in device OOBE (out‑of‑box experience). The removal of Mobile Plans does not prevent OEMs from collaborating with carriers for smooth setup on cellular SKUs.
Quick‑start guides and packaging for cellular laptops should include carrier activation links or QR codes to ensure first‑time user success.

Enterprises and IT

The platform change is not a removal of cellular capability, but it is a process change: device provisioning and corporate eSIM onboarding flows used today (if they reference Mobile Plans) must be updated.
Administrators who deploy corporate eSIMs should validate their carriers’ support for Settings‑triggered provisioning and coordinate with carrier account teams to confirm secure provisioning and reporting flows.
Update onboarding documentation, helpdesk scripts, and Intune/MDM playbooks to reflect carrier web flows and the Settings‑consent step.

Privacy, security, and consumer protection analysis

Privacy and consent

The convenience of automatic provisioning rests on sharing device identifiers such as EID and IMEI. This raises legitimate questions:
What exactly do carriers store?
How long are device identifiers retained and linked to user accounts?
How is consent logged and revoked?
Clear, explicit consent dialogs in Windows Settings are required. Carriers must publish retention and processing policies to ensure transparency.

Security and fraud concerns

Moving purchasing and payment to carrier websites centralizes payment processing with operators. Carriers must maintain strong payment security (PCI compliance, anti‑fraud measures, secure SSO flows).
Automatic provisioning paths should include strong verification to prevent unauthorized activation (for example, tying provisioning to account identity checks or short-lived one‑time tokens).
Enterprises should require carrier assurances and SLAs before enabling automatic provisioning for corporate devices.

Consumer protections

App‑store mediated purchases sometimes offer additional dispute/resolution routes; with purchases on carrier sites, users must rely on carrier refund and dispute processes. Carriers must be prepared to handle consumer disputes efficiently.

Fragmentation and UX risk

The primary downside is fragmented user experience. Carrier websites vary widely in quality; inconsistent instructions or desktop‑unfriendly checkouts will create friction.
Users who relied on a single in‑OS funnel may face confusion; helpdesks should expect increased tickets during the migration window.

Practical migration checklist — end users

Inventory devices that currently use the Mobile Plans app and note carrier names, plan details, and renewal dates.
For each carrier:
Bookmark the carrier’s eSIM/BYOD activation page.
Confirm whether the carrier lists Windows‑specific instructions.
Test the Windows Settings eSIM provisioning flow on a non‑critical device to confirm the experience: Settings > Network & Internet > Cellular.
If reliant on MVNOs/eSIM vendors used for travel (Airalo, Ubigi, GigSky, etc.), verify that their web activation or QR flows work correctly on Windows.
Preserve account credentials and take screenshots of current plan pages where needed until migration is complete.
If immediate provisioning is needed in the field, keep at least one QR‑based fallback option or a carrier support contact available.

Practical migration checklist — carriers and MVNOs

Publish a Windows activation guide and optimize checkout for desktop browsers.
Support at least two provisioning paths: Settings‑triggered automatic provisioning and QR/activation‑code fallback.
Test provisioning flows with Windows devices and document any user agent or browser assumptions that need special handling.
Publish clear privacy and retention disclosures for device identifiers.
Provide single‑use QR generation or activation links that Windows can consume easily.

Practical migration checklist — OEMs and device managers

Update OOBE and quick‑start documentation to include carrier activation links and Windows‑specific guidance.
For bulk deployments, coordinate with carrier enterprise teams to enable corporate provisioning pathways.
Update device provisioning scripts that link to Mobile Plans and rework them to use carrier portals or Settings APIs where applicable.

Strengths and opportunities

Reduced engineering and maintenance burden for Microsoft and a simpler OS footprint.
Greater carrier control over commerce, billing, SSO and identity workflows — carriers can implement richer bundles, loyalty systems, and refunds.
Potentially faster feature delivery from carriers who iterate on web portals faster than an in‑OS storefront would allow.
Opportunity to unify eSIM provisioning standards across desktop web flows, benefiting the broader eSIM ecosystem.

Risks and areas to watch

Fragmented UX: Users must move between Windows and multiple carrier portals; inconsistent experiences are likely.
Privacy inconsistency: Carriers may differ in how they log and retain device identifiers; users must be informed and given revocation means.
Support load: Helpdesks and carrier support teams should prepare for increased tickets, especially for multi‑carrier edge cases.
Consumer protections: The loss of an app-store mediation layer means refunds and disputes are subject to carrier policies; users should prefer carriers with clear, consumer-friendly processes.
Verification gaps: If carriers implement automatic provisioning without robust verification, risk of erroneous activations increases.

Recommendations — what Microsoft, carriers, OEMs and IT should do now

Microsoft

Publish a clear, public retirement roadmap with specific notices for enterprise tenants via Message Center and Tech Community.
Provide a developer and partner checklist for carriers to test Settings‑triggered provisioning.
Ensure the Settings consent UI is unambiguous and logs user decisions in a clear, auditable way.

Carriers

Deliver a public “Activate on Windows” landing page with both automatic and fallback flows.
Implement short‑lived, single‑use tokens or verification checks to pair web checkout with device provisioning securely.
Publish privacy and retention policies for device identifiers and provide clear revocation instructions.

OEMs

Add carrier activation links and QR codes to packaging and OOBE for cellular SKUs.
Work with carrier partners to ensure first‑boot experiences remain frictionless.

Enterprises and IT

Audit devices that rely on Mobile Plans now.
Test corporate eSIM onboarding with chosen carriers ahead of the retirement date.
Update helpdesk documentation and train staff on the new carrier web + Settings flow.

Final analysis and outlook

Retiring the Mobile Plans app is a measured, platform‑level consolidation that reduces Microsoft’s maintenance burden and hands commerce control to carriers. For most users the change is likely to be invisible over time — existing eSIM profiles remain active, and Windows Settings already supports eSIM provisioning. The surface risk is concentrated in the migration window: users who relied on a single in‑OS flow will have to adapt to carrier web portals, and carriers must be ready to support desktop users and to respect privacy and consent expectations.
This transition exposes both opportunity and friction. Carriers that proactively publish desktop‑friendly Windows activation flows and support Settings‑triggered provisioning will deliver an equal or better onboarding experience than the app did. Carriers that do not will create avoidable friction and increase support costs. Enterprises and OEMs that prepare now — auditing dependent devices, updating documentation, and testing carrier provisioning — will manage the change smoothly.
The technical foundation for eSIM provisioning in Windows remains intact. The next 12–18 months are about coordination, clear communication, and implementation quality. Where carriers and Microsoft coordinate effectively, the result will be a modern, secure, and scalable provisioning experience for always‑connected Windows devices; where coordination is thin, users and helpdesks will shoulder the friction.

Conclusion
The retirement of Mobile Plans is not the end of cellular on Windows; it is a reallocation of responsibilities. The practical consequences hinge on execution: clear carrier guidance, a polished Settings consent and provisioning experience, and proactive OEM and enterprise preparation will determine whether the transition is a background maintenance win or a visible support headache. Users and administrators should inventory affected devices now, test the Settings eSIM flow, and confirm carrier readiness to avoid surprises before the app is removed on February 27, 2026.

ChatGPT · Aug 29, 2025

Microsoft is removing the built‑in Mobile Plans app from Windows and replacing the in‑app storefront with a web‑first flow that uses carrier websites plus the native Settings eSIM provisioning experience, a change that will affect how always‑connected PCs buy and manage cellular data. (neowin.net)

Background / Overview

The Mobile Plans app has long been a small, specialized component in Windows for devices with cellular hardware. Its purpose was simple: provide a consistent in‑OS discovery and purchase path so users could find participating carriers, complete a purchase, and have an eSIM profile delivered to their PC without leaving Windows. That convenience reduced friction for laptops and tablets with LTE/5G radios, and it gave carriers a predictable Windows channel. Microsoft’s documentation and device OEM guidance historically described this workflow in detail. (learn.microsoft.com)
Now Microsoft is consolidating that experience. Instead of a separate app that lists operators and links into carrier commerce, users will be sent to the carrier’s website to purchase or manage plans. Windows will offer the provisioning surface — the Settings > Network & Internet > Cellular flow — and can prompt users to share device identifiers (for example, EID or IMEI) with the carrier to allow automatic eSIM provisioning when the operator supports it. Microsoft says the Mobile Plans app will continue to function in the near term but has scheduled its retirement; multiple industry outlets report the functional end date as February 27, 2026. (theregister.com, neowin.net)

What’s changing — the practical user journey

Today (how Mobile Plans worked)

The device detected cellular capability and suggested Mobile Plans when appropriate.
The app showed supported carriers and directed users to an operator portal.
The carrier handled checkout and pushed an eSIM profile to the device.
The Mobile Plans UI displayed active plan status and usage in one place. (learn.microsoft.com)

After the change (web + Settings model)

You’ll purchase and manage plans on your carrier’s website (desktop checkout).
During or after purchase, Windows Settings may prompt you to consent to share device identifiers with the operator to permit automatic provisioning.
If you consent and the carrier supports it, the operator can push the eSIM profile to your device through Windows’ provisioning APIs — no QR scanning or code entry required.
Existing eSIM profiles and active subscriptions remain functional; you’ll manage them on the carrier’s site going forward. (neowin.net, support.microsoft.com)

This is a subtle but important shift: Microsoft is removing the centralized discovery/checkout UI and keeping the provisioning plumbing in Settings. The result is that carriers control commerce while Windows retains the ability to accept provisioning instructions and install eSIM profiles.

Timeline and availability — what Microsoft and the press say

Multiple technology outlets report the Mobile Plans app will stop functioning after February 27, 2026, at which point Microsoft will remove it from the Microsoft Store and stop listing it in documentation. Microsoft has reportedly been testing the replacement flow with select carriers and expects the Settings‑mediated identifier‑sharing capability to be available prior to the retirement, with press indicating trials and phased enablement through 2025. However, the exact public rollout cadence and Insider channel timing have not been centrally documented in a single, public Microsoft Tech Community post at the time of reporting; that means some schedule details appearing in the press should be treated as reported rather than official until Microsoft posts a dedicated retirement notice. (theregister.com, windowsforum.com)
Because the retirement date is consequential for users and enterprises, treat the February 27, 2026 date as the working public target reported by several outlets — and verify it through official Microsoft notices or your organization’s Message Center if you manage devices at scale.

Why Microsoft is doing this (strategy, engineering, and business reasons)

Microsoft’s stated and implied motivations fall into three buckets:

Reduce surface area and maintenance: The Mobile Plans app is used by a narrower set of Windows devices (those with cellular radios). Removing an extra Store app reduces engineering, testing, and update overhead. (learn.microsoft.com)
Give carriers control of commerce: Carrier websites already support complex checkout flows, identity verification, promotions, refunds, and richer account management. Letting operators own billing and subscriptions simplifies regulatory, billing, and SKU management for carriers. (neowin.net)
Leverage platform provisioning: Windows already exposes eSIM provisioning APIs and a Settings UI where operators can direct device provisioning. Microsoft appears to be consolidating functionality into the OS core plus web flows, rather than maintaining a separate storefront app. (learn.microsoft.com)

These are reasonable engineering tradeoffs. A single dedicated app can offer a curated experience, but it also requires continuous maintenance across Windows versions, Store policies, and evolving carrier requirements.

What this means for different audiences

Individual consumers

If you already have an active plan installed on your PC, nothing breaks: your eSIM profile continues to work. Management of that plan will now happen on the carrier’s website. (neowin.net)
For future purchases, expect to open a browser, buy a plan, then accept a Windows Settings prompt to allow provisioning — or scan a QR or enter activation codes if the carrier provides them. (windowsreport.com)
If you rely on in‑app promotions or links, ask your carrier how they will reach Windows users after the app’s retirement.

Enterprises and IT admins

The OS-level capability for eSIM provisioning remains; enterprise MDM solutions such as Intune already support deploying eSIM activation codes and profiles. Admins will need to update documentation and device provisioning guides accordingly. (learn.microsoft.com)
If your provisioning and onboarding scripts referenced Mobile Plans links or deep links, those workflows must be updated to use carrier portals or the Settings eSIM APIs.

OEMs and device manufacturers

Update OOBE and quick‑start guides for cellular SKUs to include direct carrier links or instructions for Settings‑triggered provisioning.
Work with carrier partners to ensure desktop checkout pages support Windows‑specific guidance (including how to accept the identifier‑sharing prompt).

Carriers and MVNOs

Operators must add or improve desktop activation pages for Windows devices and consider integrating Settings‑triggered provisioning to avoid manual QR/code workflows.
Carriers must also provide clear privacy and retention notices explaining what device identifiers are collected and what they’re used for.

The good: benefits and conveniences

Less UI clutter in Windows — one fewer small app to maintain and update.
Carrier control and flexibility — operators can rapidly change SKUs, bundles, and checkout flows without waiting for an in‑OS app update.
Familiar web checkout — many users already buy mobile data online; moving the commerce there reduces the number of interfaces a carrier needs to support.
Automatic provisioning via Settings — when carriers support it, the Windows prompt to share device identifiers can let carriers push an eSIM profile to a PC with no manual QR scan or code entry, saving time and friction. (neowin.net, theregister.com)
Enterprise MDM parity — businesses can continue to deploy eSIMs via Intune and activation codes for managed fleets. (learn.microsoft.com)

The risks and tradeoffs — what to watch out for

Fragmentation of the user experience

Moving commerce to carrier websites means Windows users will face varying checkout and activation pages. The previously consistent in‑OS funnel is gone, so quality of experience depends on each carrier’s implementation.

Privacy and data handling concerns

The new approach relies on Windows prompting users to share device identifiers such as the EID or IMEI with carriers for automatic provisioning. That convenience raises legitimate questions:

What identifiers are stored by the carrier?
How long will carriers retain those identifiers?
How is consent logged and can it be revoked?
Will carriers link device identifiers to user accounts or long‑term billing records?

Windows documentation references the settings flow and describes identifier sharing, but individual carrier privacy practices will govern retention and use. Users should read carriers’ privacy policies and seek clarity before consenting to identifier sharing. (support.microsoft.com, windowsforum.com)

Billing and consumer protections

Purchasing directly on carrier websites changes the commerce model:

App‑store mediated protections (where applicable) are removed; carriers’ refund and dispute policies apply.
Payment flows must be secure (PCI compliance); customers should prefer carriers with robust payment protection.

Edge cases and backward compatibility

Some carriers or MVNOs might not support Settings‑triggered provisioning immediately — QR codes and manual activation codes will remain important fallbacks.
Devices sold with carrier preloads or OEM specific flows might require updated OOBE steps.

Enterprise operational risk

IT teams that relied on a consistent Mobile Plans channel for provisioning will need to validate new carrier flows and update device onboarding documentation before the app retires.

How to prepare — a practical checklist

Inventory devices that use Mobile Plans today. Note carrier and plan details.
Bookmark your carrier’s eSIM / BYOD activation page and support contacts. (windowsreport.com)
Test the Settings eSIM workflow on a spare device: buy a plan on the carrier site (or use a test activation), and confirm Windows prompts to share device identifiers and installs the profile. (neowin.net)
For enterprises: update deployment documentation and Intune/MDM workflows; test activation codes in a preproduction environment. (learn.microsoft.com)
For privacy‑conscious users: ask carriers how long they retain device identifiers and whether identifiers are linked to account metadata. Don’t consent to identifier sharing until you understand the carrier’s retention policy. (windowsforum.com)

Step‑by‑step: activating an eSIM on the new model (illustrative)

Open the carrier’s website from your desktop browser and locate the eSIM activation or BYOD page.
Start the purchase flow and complete checkout. The carrier site should include an option for “Activate on Windows” or instructions for Windows devices.
When the carrier triggers provisioning, Windows Settings (Network & Internet > Cellular) may show a prompt asking to share device identifiers with the operator. Read the prompt carefully.
If you consent, Windows will securely share the identifiers with the carrier so it can request an eSIM profile download to your device.
Accept the final confirmation dialog in Settings and allow the eSIM profile to install. The device should connect to the operator network once provisioning completes.
To manage the plan later, sign into your operator’s website — that’s now the canonical place for billing and plan changes. (windowsreport.com, support.microsoft.com)

A note on verifiability and timing

Press reporting and community posts repeatedly cite a February 27, 2026 retirement date and say Microsoft is testing the Settings‑led provisioning flow with carrier partners; those claims are consistent across multiple outlets. At the same time, direct Microsoft public messaging about rollout timing can vary — some of the detailed rollout schedule (Insider availability, exact carrier participation) appears in press reports and partner communications rather than a single, centralized Microsoft blog post. That means some schedule details are best treated as reported rather than official until Microsoft posts a formal retirement notice or Tech Community announcement. Users and IT administrators should monitor Microsoft support and Message Center posts for definitive timelines. (neowin.net, windowsforum.com)

Final analysis — is this a net win for Windows users?

The answer depends on perspective.

From a Microsoft engineering standpoint, it’s sensible: small, low‑usage Store apps cost engineering time and create fragmentation inside Windows. Consolidating the commerce surface to web portals and keeping provisioning in Settings simplifies the platform and aligns with broader web‑first trends. (learn.microsoft.com)
From a carrier perspective, it’s positive: operators gain full control over billing and product experience, enabling richer SKUs and promotions that were harder to support inside a constrained in‑OS storefront. (neowin.net)
From a user experience, privacy, and operational perspective, there are tradeoffs: users lose a uniform discovery experience inside Windows and now rely on each carrier’s site and policy. Automatic provisioning via Settings is convenient but raises privacy and retention questions that carriers must answer clearly. Enterprises and OEMs will need to adjust onboarding and documentation.

If carriers, OEMs, and Microsoft collaborate effectively on desktop‑friendly activation pages and transparent privacy notices, the transition can be smooth and even less confusing for many users. If not, the removal of a consistent in‑OS storefront risks fragmentation and support headaches for consumers and IT. The next 12–18 months will determine whether the benefits outweigh the costs.

Recommended actions (quick summary)

Individual users: inventory devices, bookmark carrier activation pages, test the new flow sooner rather than later. (windowsreport.com)
Privacy‑minded users: request carrier retention and linking policies before consenting to share device identifiers. (windowsforum.com)
IT admins: update MDM playbooks, test Intune deployment of eSIM activation codes, and verify carrier web flows for company devices. (learn.microsoft.com)
Carriers and OEMs: publish Windows‑specific activation documentation, support Settings‑triggered provisioning, and make privacy notices explicit.

Microsoft’s retirement of Mobile Plans is another example of the company trimming specialized built‑in apps and leaning on the web and core Settings experiences. For many users this will be a seamless change; for others — particularly those who relied on the integrated in‑OS purchase and notification experience — it will require minor adjustments. The critical near‑term priorities are clear: confirm the retirement schedule via Microsoft’s official channels, test carrier activation flows on Windows devices, and demand transparent privacy practices around device identifiers before consenting to automatic provisioning. (neowin.net, theregister.com, support.microsoft.com)

Source: How-To Geek Windows 11 Is Removing Another Built-in App

ChatGPT · Aug 29, 2025

Microsoft is removing the long‑standing Mobile Plans app from Windows and steering plan purchases and eSIM provisioning toward carrier websites and the built‑in Windows Settings experience, a shift that will change how always‑connected laptops and tablets are sold, activated, and supported. (neowin.net)

Background / Overview

The Mobile Plans app arrived as a convenience layer for devices that include cellular radios (LTE/5G). Its job was simple and focused: provide a single discovery surface inside Windows, list participating mobile operators, open the operator’s checkout gateway, and then accept an eSIM profile or activation instructions so the device could connect to cellular data without manual QR scans or complex steps. Microsoft documented that customer journey in its mobile broadband guidance, and the app was available on devices running Windows 10 and Windows 11 with supported carriers. (learn.microsoft.com)
Over time the app remained a relatively niche component — useful only for a subset of users who buy cellular‑equipped PCs or who travel with eSIM‑based plans. Microsoft’s engineering tradeoffs and the broader industry trend toward web‑first commerce have driven a decision to consolidate the buying experience back onto carrier websites while keeping the actual eSIM provisioning plumbing inside Windows Settings. Multiple outlets and community reporting have documented the transition plan and the reported timeline. (windowsreport.com)

What Microsoft is changing — timeline and mechanics

The headline change

The Mobile Plans app will be phased out and removed from the Microsoft Store; links to it within Windows and related documentation will be updated to point users to carrier websites and to the Settings eSIM flow. (neowin.net)
Press reporting and community summaries indicate the app will remain functional in the near term but has a reported operational end date of February 27, 2026, after which Microsoft will stop offering it as a storefront channel. Treat that date as the widely reported working target while verifying specifics through official Microsoft notices for enterprise planning. (theregister.com)

How purchases and activation will work going forward

Buying a data plan: users will shop on their carrier’s website (desktop browser), choose a plan, and complete checkout on the carrier’s site rather than inside a Windows Store app. (neowin.net)
Provisioning the eSIM: during or after checkout, Windows Settings may prompt the user to consent to share device identifiers — for example, the device EID (eUICC identifier) or IMEI — with the carrier so the operator can automatically provision an eSIM profile. With permission, the identifiers are securely passed to the carrier and the eSIM can be pushed to the device without scanning a QR code or typing an activation code. Microsoft’s support pages describe how a carrier can add a Windows PC to a mobile account and how eSIM profiles are delivered through the OS. (support.microsoft.com) (learn.microsoft.com)
Fallback flows remain: if a carrier does not support Settings‑triggered provisioning, the classic alternatives — QR codes and manual activation codes — continue to work.

What stays the same

Core eSIM and cellular driver support remains in Windows; built‑in network stacks and device radios are unaffected. Any eSIM profiles already installed will continue to function after the Mobile Plans app is retired; the difference is where you go to buy or manage the subscription.

Why Microsoft is doing this (strategy and engineering)

Microsoft frames the move as a pragmatic consolidation: maintaining a small, specialized Store app for a narrow user base creates duplicated commerce plumbing, increases maintenance overhead, and constrains carriers that want richer checkout and account management experiences. By moving commerce to carrier portals and preserving provisioning inside Settings, Microsoft reduces the in‑OS surface area while still enabling seamless provisioning when carriers support it. This aligns with broader industry tendencies to de‑duplicate niche UWP apps and centralize billing/identity flows on the web. (learn.microsoft.com)
Carriers benefit because web portals give them direct control of SKU configuration, identity verification, refunds, localized pricing, and promotional mechanics — capabilities that are more flexible on the web than inside a constrained in‑OS storefront. Microsoft’s new model hands commerce to carriers while Windows retains the role of a secure provisioning agent. (neowin.net)

How the new eSIM provisioning flow actually works

Step‑by‑step (illustrative)

Visit your carrier’s website on a desktop browser and choose “Add a device,” “Activate eSIM,” or a carrier‑specific flow labeled for Windows.
During checkout, the carrier’s portal will offer a Windows‑focused provisioning option if it supports Settings‑triggered provisioning.
The carrier requests the device’s EID/IMEI to identify the device for provisioning. Windows will display a Settings prompt asking you to allow the operator to receive the identifier. Grant consent to proceed.
After consent, the operator uses its provisioning backend to request an eSIM profile for that EID and pushes the profile to the device; Windows then installs and enables the profile. No QR code or manual code entry is required in this scenario.
To manage billing, renewals, or plan changes you return to the carrier’s website — that becomes the canonical place for account management. (support.microsoft.com)

Technical notes

Identifiers: the key identifiers discussed are the EID (the eUICC’s unique ID) and the IMEI (device equipment ID). Windows mediates consent; carriers receive identifiers only after the user explicitly allows sharing. (support.microsoft.com)
Provisioning APIs: Windows exposes eSIM provisioning APIs and Settings surfaces that carriers and OEMs can rely on to deliver and install profiles programmatically or via guided user flows. Enterprises using MDM tools can still push eSIM activation codes or profiles using established management channels. (learn.microsoft.com)

Immediate user impact — who needs to pay attention

Consumers and prosumers

Most typical consumers who already have an active cellular plan on their device will notice little change — installed eSIM profiles will keep working and mobile data continues to function. The change matters most when you buy a new plan or add a new device: instead of a single in‑OS purchase flow you’ll go to the carrier’s site and then use the Windows Settings prompt to accept provisioning. Expect to bookmark carrier eSIM pages and, in some cases, to use desktop‑centric checkout forms rather than a phone‑first flow.

Power users and frequent travelers

If you rely on multiple MVNOs or frequent short‑term eSIM purchases (daily/weekly travel plans), the variance between carriers’ web flows is likely to be the most visible change. Some MVNOs already optimize for QR code provisioning (which still works), but others will need to add explicit Windows‑friendly activation pages. Testing a spare device with your preferred MVNOs before the app is removed is sensible.

Enterprises and IT administrators

IT teams managing fleets with cellular SKUs should audit onboarding and provisioning scripts. If your organization used direct Mobile Plans links in corporate build images, OOBE steps, or documentation, update those artifacts to point to carrier portals or MDM‑provided activation mechanisms (Intune supports eSIM deployment scenarios). Communicate the change to helpdesk staff and update runbooks to include carrier web flows and the Settings prompt.

OEMs

OEMs should update quick‑start guides and packaging to include carrier links and Windows‑specific activation guidance. For devices sold with bundled cellular plans, coordinate with carrier partners to add desktop activation instructions and a clear path for users to accept identifier‑sharing prompts.

Benefits and strengths of the web‑first model

Reduced maintenance: Fewer small Store apps reduces Microsoft’s update surface and test matrix for specialized UWP experiences.
Carrier control: Operators gain flexibility to design checkout, verification, and promotions without being constrained by a separate in‑OS UX. (neowin.net)
Familiar commerce: Most consumers are used to buying mobile plans via a browser; the move aligns Windows with existing carrier ecosystems.
Native provisioning retained: Windows Settings remains the secure place to accept identifier sharing and install eSIM profiles, preserving a native provisioning capability. (support.microsoft.com)

Risks, friction points, and privacy concerns

Fragmented user experience

Moving discovery and purchases to heterogeneous carrier websites removes the consistent, uniform step‑by‑step flow that Mobile Plans provided. Users will now encounter a wide range of web designs, desktop login requirements, and identity verification steps that may increase helpdesk calls and onboarding friction.

Carrier readiness and timeline risk

Not all carriers will be ready at the same time. Microsoft has reportedly been testing the Settings‑triggered provisioning flow with selected operators, and the company expects the identifier‑sharing capability to be available prior to retirement, but the public rollout cadence and exact carrier participation levels can vary by market. Some press coverage notes the retirement date and carrier testing, while Microsoft’s centralized public messaging about timing appears distributed across partner channels rather than a single Tech Community post — that makes it important to verify readiness with your carrier. Flag this as a potential operational risk if you rely on a particular carrier or if you manage many devices. (theregister.com)

Privacy and data retention questions

Sharing identifiers such as EID or IMEI raises legitimate privacy questions. Although Windows requires explicit user consent before sharing identifiers with a carrier, carriers’ retention, processing, and secondary usage policies vary. Users and IT administrators should request clarity from carriers about how long identifiers are retained, whether they are linked to billing records, and what revocation options exist. This is not a technical flaw in Windows — it’s a governance and transparency issue that operators must address publicly. (theregister.com)

Loss of store mediation

Purchasing via carrier websites places refund, dispute, and chargeback responsibilities solely on the operator rather than offering an app‑store mediated layer. That’s appropriate for operators, but it changes the consumer protections and dispute channels users might expect from an in‑OS purchase.

How to manage and activate mobile plans in Windows after the Mobile Plans app is retired

Below is a practical, step‑by‑step guide to the new recommended workflow for buying and activating eSIMs on Windows devices.

Identify whether your device has cellular hardware: open Settings > Network & Internet > Cellular and verify the presence of eSIM or SIM options. (support.microsoft.com)
Visit the carrier’s official desktop website and locate the page for eSIM activation, “Add a Windows PC,” or “Bring Your Own Device (BYOD).” Bookmark this page for repeat use.
Start the carrier checkout and look for an option labeled for Windows or for automatic provisioning. Choose that option if available.
When the carrier requests the device identifier, Windows Settings will prompt you to allow the operator to receive the EID/IMEI. Read the prompt carefully and allow only if you trust the carrier and understand their privacy notice. (support.microsoft.com)
Accept the final confirmation in Settings to download and install the eSIM profile. After installation, the device should connect to the carrier network.
For management tasks (billing, data top‑ups, plan changes), sign into the carrier account on the carrier website — that becomes the authoritative place for subscription control. (neowin.net)

Practical tips:

If your carrier lacks a Windows‑specific activation flow, ask support for a single‑use QR code or activation code as a fallback.
Test provisioning on a non‑production device before relying on it for travel or mission‑critical work.
Record account numbers, plan details, and activation timestamps in case you need to reconcile billing or provisioning issues later.

Guidance for IT administrators and OEMs

Update onboarding scripts and OOBE materials that previously referenced the Mobile Plans app; replace them with carrier portal links and step instructions for Settings‑based provisioning.
Validate corporate carrier agreements for eSIM provisioning APIs and confirm whether carriers support Settings‑triggered provisioning for corporate device fleets. If not, rely on MDM capabilities (Intune) to deploy activation codes or profiles. (learn.microsoft.com)
Train helpdesk staff on common carrier checkout patterns and the Windows Settings consent prompt; create a quick checklist to diagnose provisioning failures (network, carrier portal session, device identifiers).

What carriers must do to avoid friction

Publish a clear “Activate your Windows PC” support page with both automatic Settings‑triggered provisioning instructions and fallback QR/activation code options for desktop users.
Ensure desktop checkout flows are tested with Windows user agents and that account linking / verification flows work smoothly on desktop browsers.
Provide transparent privacy notices for device identifiers, including retention windows, purpose, and revocation mechanisms. (theregister.com)

Final analysis — pragmatic consolidation with real tradeoffs

Microsoft’s retirement of the Mobile Plans app is a pragmatic engineering decision that trades a curated in‑OS storefront for a leaner platform footprint and greater carrier flexibility. For Microsoft and many carriers, this is a sensible consolidation: it reduces duplicated engineering effort and aligns commerce with existing operator systems, while preserving native provisioning via Windows Settings.
But the move is not without costs. The predictable, uniform discovery and purchase funnel that Mobile Plans provided will be replaced by a more fragmented, carrier‑dependent landscape. That increases the importance of carrier readiness, clear Windows documentation, and proactive communication to users — especially enterprises that manage large fleets. Privacy questions about device identifier handling and carrier data retention also deserve explicit answers from operators to maintain user trust. (theregister.com)
Until Microsoft publishes an explicit, centralized retirement bulletin with a detailed Partner and Enterprise transition plan, treat reported dates (including the February 27, 2026 operational end date widely quoted in the press) as the working public target and verify with Microsoft’s official Message Center posts or carrier notices when planning migrations at scale.

Actionable checklist — what to do now

Inventory devices that depend on Mobile Plans and note carrier and plan details.
Bookmark carrier eSIM activation pages and request Windows‑specific instructions where absent.
Test the Settings > Network & Internet > Cellular eSIM flow on spare hardware before the Mobile Plans app is removed. (support.microsoft.com)
For IT admins: update Intune/MDM playbooks and helpdesk runbooks to reflect carrier web flows and Settings provisioning prompts. (learn.microsoft.com)
Privacy‑minded users: ask carriers about retention and use of your device identifiers before consenting to share them.

Bringing these steps together will reduce friction and preserve always‑connected workflows as the ecosystem moves from an in‑OS storefront to a carrier‑driven web model with Windows Settings acting as the secure provisioning agent.

Microsoft’s retirement of the Mobile Plans app is an inflection point for how Windows integrates with mobile operators: the operating system keeps the secure, native provisioning surface while commerce returns to the web. The transition will be smooth for many, but the degree to which carriers and OEMs prepare desktop‑friendly activation paths and transparent privacy policies will determine whether this change is a win for convenience — or a source of avoidable support headaches.

Source: Windows Report Microsoft Retires Mobile Plans App in Favor of Web-Based Experience

ChatGPT · Aug 30, 2025

Microsoft is retiring the long-neglected Mobile Plans app and shifting eSIM purchase and management workflows to carrier websites and the built-in Windows Settings experience — a quiet but meaningful change that will take effect when the app stops functioning on February 27, 2026, and ushers a new, web-first model for cellular connectivity on Windows laptops and tablets.

Background

The Mobile Plans app was created as a convenience gateway for Windows devices with cellular radios. Its job was simple: detect a cellular-capable PC, present participating carriers or gateway pages, and shepherd a user from discovery to checkout and eSIM provisioning. The app traces its roots to the Windows 10 era and has continued as a niche storefront inside the OS for devices sold with LTE/5G modules.
Over the last year Microsoft has signalled a change in direction: rather than host a separate storefront inside Windows, the company will rely on carriers’ web portals for plan purchase and on Windows Settings for provisioning and identifier consent. The reported operational end date for the Mobile Plans app is February 27, 2026. Existing eSIM profiles already installed on devices will continue to function after the app is retired; however, management and future purchases will primarily be handled through carrier websites and the Settings eSIM flow.
Note: the February 27, 2026 date has been widely reported in industry coverage; readers should verify specific timelines with official Microsoft communications or their carrier because public messaging and partner notifications can vary.

Why Microsoft is retiring the Mobile Plans app

Microsoft’s rationale is pragmatic and mirrors broader platform trends: consolidate small, low-demand apps into OS settings or web experiences to reduce maintenance overhead and give partners more control over commerce.

Reduce engineering and maintenance surface. Mobile Plans served a very specific user segment (cellular-enabled PCs). Maintaining an in‑OS storefront involves update, testing, payment plumbing and regulatory compliance that carriers already manage on their own web portals.
Put commerce and support under carrier control. Carriers want direct control of checkout, price tiers, promos, refunds and identity verification. Carrier websites let them evolve their UX faster than a constrained in-app funnel.
Leverage built-in eSIM provisioning. Windows already supports eSIM activation via Settings, QR codes and activation codes. Windows will now mediate identifier consent (EID/IMEI) and let carrier websites trigger provisioning where supported.

This is consistent with a trend to move specialized functionality out of standalone UWP/Store apps and into either the OS Settings surface or the open web, where operators and vendors can iterate faster.

What changes for users and admins

Immediate effects for consumers

Existing eSIM profiles and active cellular connections will continue to work after Mobile Plans is retired.
To purchase or manage plans, users will need to visit the carrier’s website (or use the provider’s existing activation mechanisms such as QR codes or activation codes).
Windows Settings will become the canonical OS surface to accept device-identifier sharing prompts and to complete eSIM provisioning when carriers support that flow.
If a carrier implements Settings‑triggered provisioning, the checkout process on the carrier’s website can trigger a Windows prompt that — with the user’s explicit consent — shares device identifiers (EID, IMEI) to allow automatic eSIM installation without manual QR scans or typed codes.

Effects for enterprise and IT managers

Enterprises that deploy eSIM-capable devices via MDM (for example Microsoft Intune) should verify their processes for provisioning activation codes and commands remain functional and update deployment guides.
Admins should audit which devices in their fleet rely on Mobile Plans for discovery/activation and plan a migration to carrier or MDM-driven workflows before the retirement date.
Messaging and onboarding materials (OOBE scripts, enrollment documentation) must be updated to provide carrier links and instructions for cellular activation.

Effects for carriers and OEMs

Carriers need to publish Windows‑friendly activation pages and ensure their checkout systems can support desktop/Windows flows and the optional Settings-triggered provisioning model.
OEMs may want to include carrier activation links in quick-start guides, packaging, or OOBE to reduce friction for customers buying cellular SKUs.
MVNOs and international sellers must verify compatibility with Windows’ eSIM provisioning methods (QR, activation code, web-triggered provisioning) and provide explicit instructions for laptop and tablet buyers.

How eSIM provisioning on Windows works now (practical overview)

Windows supports multiple ways to add an eSIM profile. The Settings experience will be the primary OS-managed surface once Mobile Plans is retired.

Add an eSIM profile via Settings
Open Settings > Network & Internet > Cellular > eSIM profiles.
Choose to add a profile by searching for available profiles or by entering an activation code.
If using a QR code, the camera on the PC can scan it (or you can use a mobile device and manual code entry).
Provide any confirmation codes your carrier requires and accept the prompt to download and install the profile.
Add via carrier website + Settings-triggered provisioning
Purchase the plan on your carrier’s desktop checkout.
When the carrier requests it, Windows Settings may prompt to share device identifiers (for example EID and IMEI). You must approve this explicit consent.
After consent, Windows securely passes the identifiers to the carrier and the eSIM profile is automatically provisioned without scanning a QR code or manually entering codes.
Add via QR code or activation code
Many carriers still issue QR codes or single-use activation codes; these remain supported fallback mechanisms.

These flows let Windows both remain the point of installation and let carriers retain commerce and billing control through their web portals.

Security, privacy and legal considerations

Moving plan purchases to carrier websites and enabling identifier sharing raises important considerations.

Explicit consent matters. Windows will present a prompt before sharing device identifiers; that consent step is crucial and should describe precisely what identifiers will be shared (for example EID/eUICC ID and IMEI).
Carrier data handling and retention. Once identifiers are shared, operators become the custodians of those device identifiers. Users should review carrier privacy policies and request clarity about how long identifiers are retained, how they’re used for account linking, and whether they’re shared with third parties.
Payment and refund policies. Purchasing through carrier websites places payment processing under operator control, which may mean different refund/chargeback rules compared with in‑app purchases overseen by platform storefronts.
Enterprise privacy controls. Organizations should assess whether automatic web-triggered provisioning fits their device enrollment policies, especially for devices with corporate identity or strict telemetry requirements.
Attack surface changes. Shifting to web checkout means the usual web threats (phishing, fake pages, supply-chain compromise) become the primary concerns. Carriers must implement strong anti-fraud and anti-phishing mechanisms and verify referral flows.

Organizations and privacy-conscious users should document which identifiers are shared and insist carriers publish retention and usage policies for those identifiers.

Potential pitfalls and practical risks

While the technical migration is straightforward for many users, several risks and pain points deserve attention.

Fragmented carrier support. Not all carriers will adopt the Settings-triggered provisioning flow right away. Users may encounter inconsistent activation instructions across providers.
Broken deep links and notifications. Removing the Mobile Plans app will break any deep links, in-app operator notifications, or promotional flows that previously funneled users into the app.
Loss of a unified Microsoft-managed storefront. The convenience of a single, familiar in‑OS shopping experience goes away. Less tech-savvy users may get confused navigating disparate carrier pages.
International and MVNO compatibility. Some MVNOs or overseas carriers might not support Windows-specific activation flows or might rely on mobile-only onboarding that’s not optimized for desktop checkouts.
Timing and rollout gaps. If Microsoft’s Settings feature and carrier implementations are not synchronized, users could hit interim states where web checkout does not trigger automatic provisioning and manual QR/codes are necessary.
Enterprise deployment complexities. Organizations that previously relied on Mobile Plans for standardized onboarding will need to update provisioning SOPs and possibly integrate activation codes into MDM workflows.

These are survivable issues, but they will create friction during the transition window and require good coordination between Microsoft, carriers, OEMs and IT organizations.

Migration checklist — what every user should do now

Inventory devices: identify laptops and tablets that currently use Mobile Plans or have cellular radios.
Record carrier details: note active plans, account IDs, phone numbers and any one-time activation codes.
Bookmark carrier activation pages: save direct links to carrier eSIM / BYOD activation instructions for Windows devices.
Test flows early: if cellular connectivity is critical (for travel or mobile workflows), attempt a carrier checkout and a Settings-driven provisioning test well before the retirement date.
Back up account information: capture screenshots of plan pages, support contact info, and any subscription numbers.
Request Windows-specific guides: ask carriers and MVNOs whether they have Windows desktop activation instructions or direct “Activate on Windows” flows.
Update OOBE materials: if you sell or manage devices, add explicit steps and carrier links to your out-of-box and setup guides.

Following these steps reduces the likelihood of last-minute interruptions to always-connected workflows.

Guidance for carriers and OEMs

Publish a clear “Activate on Windows” page that supports:
Desktop-first checkout and explicit device selection.
Settings-triggered provisioning support (if you plan to implement it).
QR code fallback and activation-code fallback methods.
Test with Windows user agents and flows: ensure your checkout detects Windows devices and exposes a clear activation path.
Document identifier usage: make privacy and retention policies for device identifiers explicit on activation pages.
Provide support channels: route Windows device activation queries to specialist support or provide a Windows-specific FAQ.
OEMs should update packaging and quick-start guides with activation links, and work with carriers to embed Windows-ready provisioning links in OOBE.

A cooperative approach will minimize user frustration and protect the carrier’s revenue path for laptop and tablet data plans.

The impact on 5G Windows laptops and always-connected PCs

The retirement of Mobile Plans will not remove cellular capability from Windows devices. 5G and LTE laptops — from Surface to Lenovo ThinkPad X1 Carbon and other vendors offering integrated cellular modules — will continue to function normally.

Connectivity remains the same. Cellular drivers, modem firmware and Windows’ networking stack are unaffected. eSIM and physical SIM support are preserved.
Activation and management change only. Users will use carrier sites, QR codes or Settings rather than the Mobile Plans app for purchasing plans and provisioning.
5G remains a valuable option. For users who rely on consistent mobile bandwidth (high-mobility professionals, remote workers, journalists), integrated 5G or LTE continues to be a smoother alternative to tethering a phone, offering lower latency and full-time connectivity.

In short, the hardware and protocol benefits of 5G Windows laptops remain intact. What changes is the route to buying and managing the data plan.

What to expect during the transition window (timeline and rollout)

Microsoft has been testing a Settings-mediated identifier-sharing flow with selected carrier partners; these tests are intended to let the carrier’s web checkout trigger eSIM provisioning on approval.
The feature is expected to be available in Windows Insider channels prior to broad rollout. Microsoft indicated the Settings flow would be generally available before the end of 2025, and carriers were expected to add support during 2026.
The Mobile Plans app will reportedly stop functioning on February 27, 2026; until then the app remains available for users who prefer it.

Because some specifics are managed through partner channels and Message Center notices for enterprises, users and admins should confirm the schedule with Microsoft support pages, their device OEM and carrier contacts.

Step-by-step: set up eSIM on Windows (concise walkthrough)

Verify your device supports eSIM: Settings > Network & Internet > Cellular and look for eSIM profile options.
Choose a path:
Carrier website purchase: complete checkout then accept the Windows Settings prompt to share device identifiers if the carrier supports it.
QR code: scan the QR from the carrier using your device’s camera when prompted in Settings.
Activation code: enter the provided activation code in Settings > Network & Internet > Cellular > eSIM profiles.
Confirm the profile download and accept any carrier confirmation codes.
Manage profiles in Settings: you can switch between installed eSIM profiles, delete profiles, and rename them for convenience.
For enterprise deployments, use your MDM to push activation codes or pre-provision profiles where supported.

These steps will cover most scenarios once Mobile Plans is gone.

Bottom line: pragmatic consolidation, not a connectivity endgame

The retirement of the Mobile Plans app is not a removal of cellular support from Windows; it is a consolidation of where commerce and provisioning are handled. Microsoft is streamlining the user journey by letting carriers own the purchase experience while the OS remains the secure provisioning surface.
This shift reduces Microsoft’s maintenance burden and gives carriers control over commerce, but it requires coordinated work from carriers, OEMs and enterprise IT teams to avoid a fragmented user experience. Users who rely on always-connected PCs should prepare now: inventory devices, test carrier flows, and ensure carriers provide clear Windows-specific activation instructions.
For most Windows owners the change will be transparent. For others — especially those who rely heavily on in-app convenience or who use smaller MVNOs — the transition may require more hands-on preparation. The safest course is to test activation and provisioning well before February 27, 2026, document your carrier credentials, and keep a plan for manual QR or activation-code provisioning if automatic Settings-triggered flows are not yet supported by your carrier.

Microsoft’s move is modest in scope but emblematic of a broader trend: operating systems will increasingly act as the secure device surface for critical operations while leaving commerce and customer relationship management to service providers’ web platforms. For Windows users who need uninterrupted mobile broadband, the hardware, protocols and eSIM support remain; the control panel for acquiring and managing those plans is simply moving to the web.

Source: Windows Central Another Microsoft app bites the dust — Mobile Plans app gone in 2026

ChatGPT · Sep 1, 2025

Microsoft is retiring the long‑standing Mobile Plans app in Windows and moving plan discovery and purchase to carrier websites while keeping eSIM provisioning inside Windows Settings — a transition Microsoft says will take effect when the Mobile Plans app is removed and support ends in late February 2026.
The change is less about cutting cellular support from Windows and more about consolidating where commerce happens: carriers will own checkout and subscription management, while Windows will act as the secure provisioning surface that installs eSIM profiles and mediates device‑identifier consent (EID/IMEI) during activation. Insiders already have early access to the Settings‑mediated flow today, and Microsoft has signalled the public rollout of the new integration ahead of the Mobile Plans retirement window.
This feature‑level rewrite is small in scope but high in operational impact for a subset of users: always‑connected laptops and tablets that rely on in‑OS plan discovery and one‑click provisioning. The practical result is that existing cellular profiles and drivers remain untouched, but the storefront and management UI you may have relied on will change — and carriers will need to update their web portals to support the new Windows activation flow.

Background / Overview

Mobile Plans arrived as a convenience layer inside Windows to make it easier for devices with LTE/5G radios to discover participating operators, purchase short‑term data bundles, and receive eSIM profiles without leaving the operating system. The app provided a consistent discovery→checkout→provisioning funnel that reduced friction for users buying cellular access for a laptop or tablet.
Over time Microsoft reassessed the engineering cost and partner dynamics for an in‑OS storefront. Carriers generally prefer to control commerce — SKUs, refunds, identity verification and billing — and web portals let them iterate faster than a constrained in‑app funnel. At the same time, Windows already contains the plumbing to install eSIMs; preserving that provisioning surface while delegating checkout to carriers is a natural consolidation.
Microsoft’s public messaging frames the change as a simplification: stop maintaining an extra app and rely on carrier websites plus a secure OS prompt that shares device identifiers when the carrier supports automatic provisioning. Multiple independent press accounts report the Mobile Plans app will stop functioning on February 27, 2026, and Microsoft will remove it from the Microsoft Store; users and admins are advised to verify timelines via Microsoft’s official documentation and Message Center notices.

What Microsoft is changing — the essentials

The Mobile Plans app will be retired and removed from the Microsoft Store around February 27, 2026.
Purchases and subscription management will move to mobile operator websites (desktop browser) rather than an in‑OS storefront.
Windows Settings will remain the provisioning surface: after purchase, the OS can mediate secure sharing of device identifiers (for example EID and IMEI) to allow carriers to push eSIM profiles automatically, with no QR codes or manual codes required where carriers support the flow.
Existing installed cellular profiles and drivers continue to work; only the discovery/purchase UI changes.

These are the most load‑bearing facts for readers planning their migration or support strategies; treat the public retirement date as the working timeline reported across industry outlets while verifying with official Microsoft notices if you manage devices at scale.

Technical deep dive: eSIM, EID/IMEI and the Settings‑mediated flow

How eSIM provisioning works today

An eSIM (embedded SIM, technically an eUICC) stores carrier subscription profiles that can be installed by a carrier’s provisioning server. Traditional activation methods include scanning a QR code supplied by the operator or typing an activation code into a device; carriers can also push eSIM profiles to devices that support remote provisioning using the eUICC’s EID (the eUICC identifier) and the device IMEI for device verification. Windows has supported eSIM profile installation through Settings for several releases.

What the new Settings integration adds

The Windows Settings integration changes the trigger point: instead of arriving via an in‑app storefront, a user completes checkout on a carrier website and then is presented with a secure Windows Settings prompt asking permission to share the device’s identifiers (EID/IMEI) with the carrier. With consent, the carrier can remotely provision the eSIM into the device’s eUICC without QR scanning or manual entry — a near‑seamless server‑to‑device push. Microsoft has been testing this Settings‑mediated identifier sharing with carrier partners and is making the flow available to Windows Insiders ahead of general availability.

Windows UI surface

The relevant controls are available in Settings > Network & Internet > Cellular, where eSIM profiles are added, named, removed and switched. That management surface will remain the place to accept provisioning requests and to manage installed profiles after the Mobile Plans storefront is retired.

Timeline and rollout: what we know and what’s still unclear

Windows Insiders: the identifier‑sharing/provisioning flow is already in Insider channels for testing.
Public rollout: Microsoft expects the Settings‑mediated provisioning feature to be available broadly before the end of 2025, with carrier enablement continuing into 2026.
App removal: multiple outlets report the Mobile Plans app will stop functioning on February 27, 2026; Microsoft will remove the app from the Store and update documentation accordingly. Treat this as the widely reported operational target and verify via official Microsoft channels for enterprise planning.

A critical caveat: because carrier participation and partner enablement are partly out of Microsoft’s hands, real‑world readiness will vary by operator and market. Microsoft has acknowledged that carriers must adapt their web checkout flows and implement a Windows activation trigger; the company has been working with “select partners” in trials, but public partner lists and per‑carrier schedules remain sparse. Administrators should assume staggered rollouts and plan for fallback activation methods.

Impact analysis — who wins and who shoulders friction

Strengths and benefits

Less maintenance for Microsoft and clearer responsibility boundaries: By moving commerce to operator sites, Microsoft reduces the surface area of code it must maintain and leaves billing, refunds, and SKU management to operators who already do that at scale.
Potentially richer carrier experiences: Carriers can implement full account linking, identity verification and cross‑product bundles in their web portals without working around an in‑app constraint. That may deliver better bundled offers and faster iterations for promotions.
Native provisioning retained: Windows remains the secure sandbox that installs eSIM profiles; visually the changes are mainly where commerce happens, not in the networking stack. eSIM and physical SIM support, drivers and modem firmware are unaffected.

Risks and downsides

Fragmented user experience: Carrier portals vary wildly in quality, accessibility, and desktop checkout flows. Users accustomed to a single Windows UI will be bounced to idiosyncratic websites, which can increase confusion and support volume.
Carrier readiness uncertainty: Smaller carriers and many MVNOs may not prioritize implementing the Windows activation trigger; users of those providers could face slower or manual onboarding that requires QR codes or code entry.
Inconsistent privacy/consent surfaces: If some carriers implement the Settings‑triggered provisioning while others rely on manual codes, the consent experience will differ and could create legal or UX concerns that need careful documentation and communication.
Enterprise operational friction: IT teams that built helpdesk scripts around the Mobile Plans UI will need to update training materials and MDM workflows; some corporate provisioning scenarios may require vendor coordination or different MDM strategies.

Practical checklist — what readers should do now

For individual consumers and road warriors

Inventory devices with cellular radios and list the active plans, carrier names, and renewal/expiry dates.
While the Mobile Plans app is still functioning, test any plan purchases you rely on and capture the carrier’s activation instructions. Keep screenshots or saved QR codes for fallback purposes.
Visit your carrier’s website today and search for an eSIM activation page. Bookmark it and save any support articles about Windows‑specific activation.
If you have a spare device, run a dry‑run: purchase a small plan, complete activation, and confirm the eSIM installs via Settings > Network & Internet > Cellular. Make note of each carrier’s flow (direct provisioning, QR, code required).
If your carrier doesn’t publicly document a Windows‑specific flow, open a support ticket and ask whether they plan to support Windows Settings‑triggered provisioning and when. Save the response.

For IT administrators and helpdesk managers

Audit corporate devices for Mobile Plans dependencies and list users who rely on the app.
Update helpdesk scripts and knowledge base articles to include carrier web activation steps, QR fallback procedures, and the Settings UI path for eSIM installation.
Test carrier flows on enterprise hardware (including corporate‑branded images) to catch driver or OEM UI issues before the app’s retirement.
If you use Intune or another MDM, check whether your enrollment or provisioning profiles reference the Mobile Plans app and update any automation that targets that UI. Consider pre‑provisioning or bulk activation paths if carriers support them.
Communicate timelines to users and arrange a migration window for high‑priority employees (sales, field staff, journalists) who cannot afford connectivity disruptions.

Troubleshooting & fallback options

QR codes and manual activation codes remain a reliable fallback where carriers have not enabled server‑side provisioning. Keep any saved QR images and activation codes in a secure password manager for quick reuse.
If an operator’s web checkout is unusable, temporary tethering via a phone hotspot or using a local prepaid physical SIM can provide immediate connectivity while you sort activation.
For enterprise devices, consider temporary mobile hotspots or corporate‑issued SIM-based failover for critical roles until carrier support is verified.

Carrier readiness: what carriers must do and why they might delay

Carriers need to adapt their web portals to initiate the Windows activation flow and to accept device identifiers when the user consents. That requires:

Adding a Windows‑specific checkout trigger that invokes the Settings prompt, and
Backend support to map the checkout session to the device EID/IMEI and to push the eSIM provisioning request to Microsoft’s provisioning endpoints.

Microsoft has published partner guidance and run early trials with select partners, but public partner lists and per‑carrier timelines are limited — meaning real‑world support will be staggered across operators and markets. Expect the large Tier 1 carriers to prioritize enterprise and premium consumer experiences; smaller carriers and MVNOs may implement changes slowly or rely on manual QR flows longer.

Security, privacy, and compliance — what to watch

Consent mechanics: Windows will prompt users before sharing EID/IMEI with a carrier; documenting the exact consent language and audit trail will be important for enterprises and privacy teams. Ask carriers how they log and retain identifier exchange records.
Data minimization: Confirm that carriers request only the identifiers necessary to provision the eSIM and that they inherit appropriate retention and access controls. Verify that provisioning traffic uses secure channels and that carrier endpoints adhere to your organization’s compliance posture.
Regulatory fit: In jurisdictions with strict device or subscriber‑data rules, carriers and enterprises should verify that the Settings flow aligns with local telephony regulations and data protection laws. If in doubt, escalate to legal/compliance.

Strengths, weaknesses and the bottom line

Microsoft’s decision to retire Mobile Plans is pragmatic: it reduces duplicated engineering effort, pushes commerce to the parties that manage billing, and preserves the OS’s role as the secure provisioning surface. For the majority of users who buy cellular‑equipped PCs only occasionally, the transition will be transparent once carriers implement the Settings trigger.
However, the transition risks a fragmented and inconsistent experience during the rollout. Smaller carriers and MVNOs may lag, helpdesk volumes can rise, and privacy consent surfaces may vary across operators. Enterprise admins should treat February 27, 2026 as a working deadline for planning, but validate per‑carrier schedules and test the Settings provisioning flow well in advance.

Quick list: what to ask your carrier today

Do you support Windows Settings‑triggered eSIM provisioning (server push) for eUICC devices? If yes, when will it be available for consumer and enterprise accounts?
If you do not support server push, what are your recommended Windows activation options (QR, activation code, manual enrollment)?
Do you provide Windows‑specific documentation for eSIM activation and troubleshooting? Please provide links or KB articles.
For enterprise accounts, can you support bulk provisioning or MDM‑driven activations? What information is required from IT?

Final recommendations

Act now to inventory devices and test carrier flows while the Mobile Plans app is still available.
Prioritise testing on spare hardware and update helpdesk and MDM scripts to reflect carrier web flows and the Settings UI path.
Confirm timelines with your carrier and maintain QR/code fallbacks until you can prove carrier server‑side provisioning works reliably for your devices.
For enterprise environments, run staged pilots and require carriers to provide written activation instructions and SLAs for provisioning issues.

Microsoft’s move marks a modest but meaningful shift in how Windows handles mobile connectivity: the operating system keeps control over secure provisioning, while carriers regain the commerce lane. For most users this will be an operational change rather than a connectivity loss — provided carriers, OEMs and IT teams plan and test before the app’s scheduled retirement.

Conclusion: treat the Mobile Plans retirement as a planned migration, not a catastrophe. Start the simple work now — inventory, test, document and update support materials — and the transition to carrier‑hosted checkout plus Settings‑driven provisioning should be manageable.
