I am using the EC200 LTE module for network and SMS functionalities in our project. We are using an eSIM that supports both Airtel and BSNL profiles. Currently, the Airtel profile is working properly for internet data posting and SMS functionalities.
However, we haven’t yet tested the BSNL profile. I would like to configure it so that Airtel is the primary network. If the Airtel network is unavailable, I want the module to switch to the BSNL profile. Later, if Airtel becomes available again, I want the module to switch back to Airtel.
I have tried using AT commands but haven’t found a working solution. Kindly assist me with how to implement network switching using the EC200U module.
