    Once upon a time, I bought an unlocked, unbranded S10+ phone from Samsung direct. It had issues on AT&T and I had to return the device and buy an AT&T branded device to get all features working properly. When I bought my S20 Ultra, I just bought the AT&T branded one from Samsung direct. I had an AT&T rep say that I should be able to bring an unbranded/unlocked device to AT&T and have it work out, just fine.

    Can anyone confirm that unbranded/unlocked devices now fully function on AT&T's network??

    Unlocked N20U on AT&T... Everything works as advertised. I did lose wifi calling when I went from beta 11 to stable but got an OTA update that fixed it.

    S20U Unlocked on ATT here, works perfect. Ordered my 2nd unlocked phone (S21U). I will probably only buy unlocked phones from here on out.

    I've been using my unlocked s21 ultra for the last 3 days with AT&T without any problems. Calls, texts, cellular data, wifi calling, etc... All of it works.

    Popped my sim out of my S20 (unlocked on AT&T) into my unlocked S21 and it just worked.... I did do smartswitch before removing the sim from the old phone and putting it in the new one though.

    I moved the SIM from S20 beforehand. With SIM in S21 it updated it immediately, then did a restart before starting sync. Also Unlocked with AT&T SIM.

    Are you using the visual voicemail that came with the phone or did you have to download the Att one from the app store
