    This expert is helping you out because there weren't many active AT&T Wireless experts.

    SIM cards are blocked following three successive incorrect PIN entries. In order to unblock your phone's SIM card, you'll need to get its PUK code. You can do this online by following these steps:
    Log in to myAT&T and go to the My Phone/Device page.
    From the My Phone/Device screen, select the Unblock SIM Card link under Manage my phone/device.
    The Unblock SIM screen will display your PUK code and will give you instructions for unblocking your SIM Card.
    You also may use our Technical Support Chat or call Customer Service at 1-800-331-0500 to get help unblocking your SIM card.

    You can obtain PUK code 1 of 2 ways....

    Log into the your myWireless account section of for free if not already registered)
    go to My Services.
    go to My Device.
    go to Unblock SIM Card.
    OR call customer service from an another phone at 1-800-331-0500 and ask for the PUK code for you SIM card.
    You only have 10 attempts before the sim is permanently disabled and you will have to replace. This is a security feature specific to your sim and protects any information stored on your sim in case of theft or something.
