Hi Teltonika Support,
Our RUTM20 is showing “Data connection: Disconnected” and will not establish a cellular connection. We’ve verified the SIM is active with Verizon and power cycled the device multiple times, but the issue persists. It show Sim 1 is inserted but no Data Connection.
Also we cant seems to click the edit of the mob1s1a1, it says sim block
Could you please advise on the next troubleshooting steps?
Thank you.
