    Unlocking siemens c56

    I have an old siemens c56 I would like to use, as the screen on my current phone is broken. My current AT&T sim does not work in the phone, and it says network lock.

    I got the unlock code from AT&T, but they couldnt tell me how to use it. I tried looking online, but couldnt find instructions on how to use the code.

    I verified that it's locked by using *#0606# and the second line says multiple lock.

    How do I unlock this phone? I dont have a cable.

    Thanks

    Unfortunately you'll need a cable. Please check the A56>C56 thread. The first few pages will have instructions for you.
