I need help I hav a t-mobile sim card but a AT&T BlackBerry. Now it wants a code but the person I got it from doesn't remember the code. So what do I do?

I'm sorry you're having problems getting your device unlocked. Unfortunately, T-Mobile will only have unlock codes for T-Mobile devices. You'll want to contact AT&T for the unlock code to AT&T devices.

If it is a password just keep entering incorrect.
Over 10 attempts on a password will reset the phone.
If it is a MEP code that would be the code to unlock use with another provider. Then your friend will need to get that from AT&T or you can pay a online service to get it.
Since it is not a T-Mobile phone, they can not help in that regards.
