Re: locked my sim card on phone

The default code is 1111 however if you set a custom code you'll need to get a PUK code. 


Go to the My Phone/Device page in myAT&T and select the Unblock SIM Card link under Manage my phone/device to get the PUK code for your phone. The Unblock SIM screen will display your PUK code and will give you instructions for unblocking your SIM Card.


Here's an article with more information:
