      Hello,
      My system version on VOXLCAM is 3.8.0. I am facing issue where my modem is not able to connect to my country's LTE network. We have V2 LTE Modem installed on VOXLCAM which was working perfectly from past few months and all of a sudden it stopped working.

      I am attaching logs of voxl-modem service for your reference. I have also verified my APN for this Sim card and properly configured it via voxl-configure-modem service. Also I am using voxl-modem system startup service for starting modem on bootup and connecting to LTE network.

      voxl:/$ journalctl -u voxl-modem.service -f

          What band is your cellular network? What bands does your modem support? Do they match?

            @Chad-Sweet My region operating bands in India are 4,30 and 1. All these bands match with modem since I was using the modem since past few months successfully. All of sudden it has stopped working.
            What inference can we derive from above logs? My region code are getting fetched correctly but registration isn't happening for Sim cards. I have tried multiple sim cards as well but no success.
            Can it be hardware issue?
            Is there any way to factory reset modem?
            How to debug this further?
