After I changed remotely the cellular service from LTE to 3G I cannot anylonger reach the router through SMS. I was dumb and changed the cellular service before I checked that 3G is not anylonger available in the area.
Is there any other way I can reach the router? I read somewhere that the router should automatically go to auto if it cannot connect to a service i.e., 3G.
Hello,
Unfortunately, if the auto fallback is not triggered (as seems to be the case), restoring connectivity without physical intervention can be challenging. The available options would include:
- Physical Intervention: Performing a factory reset on-site to revert the router to its default settings and allow it to reconnect automatically to the available network.
- Connection to CLI (if accessible): If it’s possible to connect to the router’s CLI via another interface (e.g., LAN), you can execute the following command to enable automatic network mode selection:
gsmctl -A 'AT+QCFG="nwscanmode",0,1'
This command sets the device to automatically search for and connect to the available network mode.
Best regards,
