I can't make any outoing calls and I have a solid LS light. I just receive a NO CARRIER response.- Make sure the antenna is connected and the SIM is inserted correctly.
- Check the signal and registration with these commands:
AT+CSQ (a response of 10-31 is good)
AT+CREG? (0,1 is registered&0,5 is roaming).
- Check the reason for NO CARRIER with the command AT+CEER. Look up the error code in the Reference Guide.
