I need PUK code for Blackberry Curve


You can get the puk code by calling your phone service provider, the phone doesn't have a puk code, if you change the sim card it wont ask for the puk.

When I put my sim card in the phone is says invalid sim card. What do i do to fix this?


Unfortunately you will need to go the AT&T store or call AT&T customer service, your SIM card got corrupt and you will need to have it replaced, good news at least it wont cost you anything.

Invalid SIM card


Go to your provider and ask for a new sims card. They should give you one free of charge. This corrected the same problem for me.
