Device Unlock
Advanced: com.att.deviceunlock Advanced Vendor documentation
AT&T's app for requesting a network unlock on some AT&T Prepaid phones; keep it until your phone is unlocked. You can disable it, with a caveat: read what stops working first.
What it does
AT&T Device Unlock lets you ask AT&T to unlock a prepaid phone from its network so it accepts other carriers' SIM cards. AT&T preloads it on some AT&T Prepaid devices, and AT&T's license for the app covers prepaid phones only. When AT&T approves the request, the unlock is applied to the phone. Newer Samsung phones show their lock status under Settings instead.
Also shown as AT&T Device Unlock.
If you disable it
On an AT&T Prepaid phone that is still locked, you lose the on-phone way to request and apply the unlock. Once the phone is unlocked, nothing you will notice.
How to disable it
On most phones Settings greys out Disable for this package, so ADB is the way to turn it off. The commands below work without root and can be undone.
Disable it (reversible)
adb shell pm disable-user --user 0 com.att.deviceunlockTurn it back on
adb shell pm enable com.att.deviceunlockThe stronger option removes it for your user only; the original copy stays on the phone and a factory reset brings it back. Prefer disabling: it is easier to undo.
Uninstall for the main user
adb shell pm uninstall -k --user 0 com.att.deviceunlockRestore after an uninstall
adb shell cmd package install-existing com.att.deviceunlockNew to ADB? Set it up in about ten minutes.
