    Hi Friend

    I have a Nokia 640 Go phone with ATT and would like to unlock it

    Can you tell me if the unlock procedure at for Nokia 640

    Steps that I followed

    1. Put in a non ATT sim
    It directly asked for the unlock code - no choice but to exit

    Next,tried using a ATT sim

    1. Keyed in ##7820#
    2. Prompted to enter the unlock code.
    Where do I get the code from? Can you please explain the process clearly.

    Arun
