How do phone upgrades work for AT&T?

Does an ATT phone have to be unlocked to work for a different ATT account?

  • I know that in order for an ATT phone to work for T-Mobile or another GSM carrier that it needs to be unlocked. But, does an ATT phone have to be unlocked to work for an ATT account?

    It should work unless you bought a used phone which was reported stolen.

No…. Locked means the phone will work with only the SIM card branded on the phone… ATT phone with ATT sim cards…. Tmobile phone with Tmobile Sim Cards…. Etc et cet cetc unlocked means the carrier lock on the SIM card is removed… the phone will work with any sim card on earth since you have an locked att phone… it will work with only an att sim card… doesn’t matter who’s account is programmed on the att sim card... just as long as the phone branded logo matches the sim branded logo… then youre good… ATT 2 ATT… Tmobile to Tmobile….. o2 to o2…… Rogers to Rogers… etc et c unlock only if you want to mix branded phones with other branded sim cards… ATT on tmobile… Tmobile on ATT… ATT on Rogers….
