CC864/Verizon not registered. Why?

  1. I have several CC864 modules for evaluation. One will not register with the cell network (+CREG: 0,0) all the time. I don’t think it is an antenna problem (it can get a GPS fix using the shared antenna) and this module isn’t yet provisioned with the carrier.

     

    In addition at+csq returns +CSQ: 17,99 so the signal is strong. AT#CAI looks ok:

    #CAI: 28,4,4627,2,425,260,6,6,6,-79,-10,0,2,0,0,0,2,0,0,0

    OK

    What could be wrong?  Is there a way to debug this or force it to register?

     

    Thanks,
