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.

1. (easyer way) When I got my Blackberry, I had to put it in a couple of times for it to work.

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.
