Samsung’s unannounced Galaxy Tab S12+ 5G appears to be headed for the U.S., with model SM-X848U turning up in Federal Communications Commission filings. Notebookcheck first reported the listing, which points to a cellular-equipped U.S. variant rather than a Wi‑Fi-only tablet.
The FCC materials indicate support for 5G, LTE, Wi‑Fi 6, Bluetooth and GNSS positioning. They also reference S Pen compatibility and microSD expansion—two features that remain especially relevant for Windows users treating a Galaxy Tab as a secondary mobile workstation or using Samsung DeX alongside a PC.

The “U” model suffix has historically been associated with Samsung hardware intended for the U.S. market. Earlier Galaxy Tab S12+ sightings used model numbers SM-X840 and SM-X846B for Wi‑Fi and international 5G configurations, respectively, according to reporting from 91mobiles and Android Authority. The newly listed SM-X848U fills in the more consequential domestic cellular version.
That matters because U.S. buyers have often faced limited choices for flagship Android tablets with native mobile data. A 5G Tab S12+ could provide always-connected DeX access, VPN connectivity, Remote Desktop sessions, and cloud-file access without depending on phone tethering or public Wi‑Fi.

Certification Is Not a Full Spec Sheet​

FCC approval confirms radio hardware, not final retail specifications, pricing, carrier availability, or release timing. Samsung has not announced the Galaxy Tab S12 line or confirmed that SM-X848U will ship under the Tab S12+ name.
Notebookcheck says prior leaks have suggested a MediaTek Dimensity 9500-series processor, but that remains unverified. A Geekbench-related report from SammyGuru has also associated the SM-X848U identifier with the upcoming tablet, offering further support for the device’s identity but not a complete picture of its configuration.

The S12+ May Restore Samsung’s Middle Flagship Size​

Reports around the emerging lineup point to a Galaxy Tab S12+ and Galaxy Tab S12 Ultra. If accurate, that would put a Plus model back at the center of Samsung’s flagship tablet strategy after the Galaxy Tab S11 generation reportedly consisted of standard and Ultra models.
For Windows-centric users, the key unanswered questions are less about benchmark scores than the practical details: which U.S. carriers will support the device, whether it will be sold unlocked, whether Samsung bundles an S Pen, and how aggressively the tablet supports multi-device features with Galaxy Book PCs and Windows 11.
The FCC appearance suggests Samsung’s U.S. launch preparations are underway, but a formal announcement later in 2026 is still the next milestone to watch.
