Our take on the Samsung Galaxy S26 Ultra SM-S948U AT&T Locked

The Galaxy S26 Ultra is Samsung's top-tier flagship phone, built around a large 6.9-inch AMOLED display, a 200MP main camera with a 5x periscope telephoto, and the S Pen stylus. This SM-S948U version is AT&T locked, so it works only on AT&T's network and its MVNO partners. It suits people who want the biggest screen, the longest zoom and stylus input, and who stay on AT&T. Against the S25 Ultra the changes are iterative, so owners of the previous model have little reason to switch, while buyers coming from older Galaxies get a clear jump in camera reach and battery life.

What reviewers say

Owners of recent Galaxy Ultra phones describe the S26 Ultra as polished and capable but familiar, with the camera zoom and screen drawing the most praise. Criticism centers on its size and weight and on how little has changed since the S25 Ultra.

What people mention
  • Camera zoomPraisedOwners say the 5x periscope and 200MP main sensor keep distant subjects sharp.
  • Size and weightCriticisedReviewers call it tall and heavy, awkward to handle with one hand.
  • DisplayPraisedThe large AMOLED panel is described as bright and smooth outdoors.
  • Upgrade valueMixedMany say it is a modest step over the S25 Ultra rather than a reinvention.
  • ChargingCriticisedSome note charging is slower than competing flagships.
  • S PenPraisedUsers who take notes or sketch value the built-in stylus.

Questions and answers

Does the AT&T lock matter if I use another carrier?
Yes. An AT&T locked phone is tied to AT&T's network and will not accept another carrier's SIM until AT&T unlocks it, and only after its unlock requirements are met.
Is it worth upgrading from the Galaxy S25 Ultra?
For most S25 Ultra owners, no. The changes are incremental, and the camera, screen and S Pen experience are close. Upgrading makes more sense from an S22 or S23 Ultra.
How does it compare with the Galaxy S26+?
The Ultra adds the 200MP main camera, the 5x periscope zoom and the S Pen, plus a larger screen. The S26+ is smaller and lighter but gives up the long zoom and stylus.
Does it have a headphone jack or microSD slot?
No. Like recent Galaxy flagships it has neither, so you rely on USB-C audio and the built-in storage.
What comes in the box?
The phone itself, a USB-C cable and a SIM tool. Samsung does not include a charger or case.
How long will it get software updates?
Samsung promises seven years of Android version upgrades and security patches for its recent flagships, which covers this model.
