Our Airtel M2M IoT sims are not connecting to internet when placed with Quectel module EC200UCNAA. It randomly connects a few times and doesn’t sometimes and has been a common issue for us.
Kindly suggest us the best possible solution.

The below is what I’m getting on Quectel AT command window:

Hi @soulman
When the command reports an error, can you use the AT+QENG=“SERVINGCELL” command to check the network status?
AT+CGACT?
AT+QIACT?
