Samsung One UI 4.0 Beta Reveals Support for eSIM in the U.S.

Samsung Galaxy S21 Ultra AH 11

The latest Samsung One UI 4.0 Beta has uncovered support for eSIM capabilities in the U.S. Although eSIM capabilities arrived with the Galaxy S21, S21+, and the S21 Ultra earlier this year, U.S. variants were left out of the compatibility list (via).

After a few months of waiting, it now seems like the Android 12-based One UI 4.0 has finally enabled eSIM support in the region. Samsung recently enabled eSIM capabilities on the T-Mobile Galaxy Note 20 and Note 20 Ultra earlier this year.

For most users, support for eSIM will be enabled when the company pushes the final version of Android 12 and One UI 4.0. With the Beta only going live a couple of days ago, the stable version is still a couple of months away. However, this revelation gives a hint of what’s to come for Samsung’s 2021 flagships and beyond.

If you’re eager to try out the new eSIM capabilities on the Galaxy S21, S21+, or the S21 Ultra, you can sign up for the One UI 4.0 beta. The beta program is open for customers of T-Mobile, Sprint, or unlocked Galaxy S21 phones. Users should try out beta versions on a spare device as such releases are generally unstable and buggy.

Samsung has talked about One UI 4.0 beta since July, although the beta release faced delays. According to industry reports, the stable version of One UI 4.0 would only roll out by early November.

As for compatibility with One UI 4.0, Samsung could send the update to over 70 Galaxy devices. This includes mid-range smartphones as well as tablets. The company will reportedly send the update to phones in the Galaxy A, Galaxy F, and the Galaxy M series. Though these phones and tablets will get the update, the timeline is currently unclear. The company usually updates its flagship lineup first, followed by mid-range and budget devices.


While we don’t have all the details yet, One UI 4.0 will likely include a handful of new features. Early information from the beta build indicates that the company brings camera zoom and other new animations. Users can also expect minor improvements to the Always-On Display and Samsung Keyboard.
