Automatic APN selection based on registered network

Hi Team,

I am facing one APN change related issue in our devices. the mcu sets the apn in modem using AT+CGDCONT command. Some days back, The network provider has changed the APN. it affected some of the devices having modem with serial no. (EC200U-CNAAA7XXX and EC200U-CNAAA9XXX). While other devices with the modems serial no. EC200U-CNAAC09701 were still communicating. How can I make the modem autocorrect the apn set by the provider. This issue has impacts thousands of devices. Requesting your prompt response.

Regards,

Hi @Kamlesh_Bharodiya1
Sorry, this depends on the carrier side, the module cannot complete the apn automatic update, the module is only the executor, the apn update needs to be entered before it can be updated.

I’ve seen that even if the operator has changed the apn, some of Device were working with the new apn - registering - sending data to server etc. While some devices were not able to establish PPP connection although they were able to register to the network. I got to know the working devices - network was able to correct the apn. But in non-working devices network was not able to correct the devices. Any insights into this behaviour? How can i make the devices consistent in communication?
