It's an AT&T branded card that I've always used in other BB devices, including my 8700c and have never encountered this problem.
Any ideas??

If you have an original Blue AT&T card, it needs to be changed to either a 64 or 3G Orange. Since the merger, the older AT&T cards are not compatable with the newer equipment. They will sometimes work but AT&T does not recommend their use in the newer phones. Rather, call Cingular/At&T and order a replacement Sim.
Good luck...
