S21 updated UI

[badpigg]

My S21 Ultra is still running UI 5.0? Why can't I update?

I have the at&t s21+ unlocked and using android 14 one ui 6. In order for me to update the operating system I have to use a at&t sim either regular or prepaid to update.

I'm having that same problem with my AT&T Tab 9. It won't update. Do i need to be actively connected to an AT&T sim card to do that?

[ohio_mike]

I believe so. See if u have a friend on at&t and try their sim card.

[CaryS21UltraS24Ultra]

I will, but prepaid AT&T sim will work also?

[ohio_mike]

It should
