You can get one on ebay, just type your phone model and they'll sell you a code for it once you email them your phone specs. Otherwise when cancelling your service, sometimes your provider will give you a code to unlock it if you request it.

try the last 4 digits of your number.

Ex. 123-4567

Punch in 4567

Your mobile is locked with at&t network.By using the code, you can remove your network lock.I found an unlocking service at Prounlocking.com .With the help of this you can unlock your mobile easily.
