Most cellphones accept a unique unlock code to release the lock set by the carrier. The code is specific to the phone's IMEI number, which is on the sticker located on the back of the device. Users can also access the number by dialling *#06# on the phone.
To start the unlock process, owners can request a free code from AT&T. Once the company receives the request information, it generates a unique code and sends it to the user, who enters it into the device to release the lock. The code only works on a single device. The company also sends detailed code input instructions specific to the user's phone model. Once unlocked, the phone accepts SIM cards from all compatible networks in the world.
Free AT&T unlocking provides users the flexibility to change providers and the ability to save on roaming charges by purchasing local SIM cards. Unlocking also increases the phone's resell value, since it makes the phone available to more carriers.Learn more about Mobile
