Password for blackberry phone?

Question

I have a blackberry phone (AT&T) from my friend and i switched the SIM cards and now the phone is asking for a password to unlock it.

Has this situation happened to anyone else?

Does anyone know of any way to obtain a password, unlock the phone or do anything just so i can use my phone?

Thanks.

Answer 1

If your forgot your password,contact your costumer service dealer. They will reset your password.

Answer 2

Ask your friend.  It's probably the password they set when they had the SIM card.
