TC63I Network registration fails | Thales IoT Developer Community

August 14, 2018 - 2:15pm, 2687 views

Hello Forum,

We use thousands of these modules that works fine but som hundreds of the modules fails during network registration.  We can monitor the trafic for each modem from our SIM card providers home page. Here we can see that the modem´s that are failing registration to the network have shiftet to a roaming profile that is not supported by our provider.

Modem is allways set to factory default "AT&F" before initiating a new transmision of data, so the operator is automaticly selected.

Do you have any suggestion how to prevent the modem from selecting a roaming profile that is not supported by our SIM card provider?

Thanks in advance Michael

FYI:

We use Telia SIM cards (Denmark)
Modems are locate in Germany
Telia have agreements with Telekom, E-Plus and TeleFonica
We can see that modems have selected O2 or Vodafone - these are not supported by Telia!
