Quetel EG25-G Network connection restoring issue

We are working in a project with Ubuntu Machines and for IOT connectivity we are using the Quetel EG25-G module. Our M2M SIM has been procured from Mobily operator and we are able to connect the network from our edge computer with IOT. Some time we are facing issue with network disconnect automatically and it doesn’t connect back with the operator network even signal is return back after minor signal issue/ network operators Access point change over.

Module : EG25-G can anyone help me to overcome this issue?

When the system is not connected to the network, you can use the “busybox microcom /dev/ttyUSB2” command in Ubuntu to enter AT mode, then type AT+QENG=“SERVINGCELL” to check whether the module is connected to the network.
