Product FAQ

Why does it take so long to log in to a 2G network?

The default settings for CNMP and CMNB may not be optimal for 2G. With other settings for CNMP (13, preferred for GSM) and CMNB (3, CAT-M + NB-IoT) it will probably be a lot faster. You can use the following AT commands during the initialization of the GSM module:
  • AT+CMNB=3
  • AT+CNMP=13
Please note that the setting AT+CNMP=13 ensures that the SIM7000G can only connect to GSM networks.
