+creg: 0,0


#1

I am having big problems with the AT+CREG? command. I have a batch of 100 modules in the field that returns +CREG: 0,0 when quaried, even while it is working perfectly and connected to the internet. I have over a 500 of the exact same modems with the same firmware 663c0gg.Q2687H 1961896 122407 14:45.

PLEASE HELP!!!
