I have a BG95 module that is having problems connecting to the cell network (ATT).
We have moved the SIM card to another modem and it works fine.
The return from CREG? changes between 3 (Registration denied) and 2 (trying to attach or searching).
I thought about the antenna but it seems to be getting signal, when no antenna is attached we just get NO SERVICE.
Any thoughts on what I can try next?
Here are some diagnostic commands I have run trying to figure out what is going on:
AT+CFUN?
+CFUN: 1
OKAT+CREG?;+CEREG?;+CGREG?
+CREG: 0,3
+CEREG: 0,3
+CGREG: 0,4
