If you're switching carriers or want to use your device internationally, unlocking your AT&T phone is a key step. Here's how it works.
Log into myAT&T > Devices & usage > Request device unlock
Follow the on-screen prompts, enter device IMEI (dial *#06#)
You'll receive confirmation and an unlock code or instructions (mostly automatic for modern devices)
Insert a non-AT&T SIM and complete setup or enter the unlock code if required
AT&T requires certain minimum usage—unlock eligibility varies by account type.
No—unlocking a device legally does not void manufacturer warranty.
Check if your AT&T device is eligible for unlocking.
