Invalid sim


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

2. Buy a new sim card.
If this does not work, then check to see if it is unlocked.

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.

Sim Card Invalid


It sounds like the device is still locked to the original wireless carrier. What you need to do is have the device unlocked (if it is a GSM BlackBerry) so that it will work with other carriers. There are several vendors that provide cell phone unlocking services. I recommend checking out HorizonWirelessOnline.com.
