Thank you, I guess I need to configure the modem.

@Uta

I don’t know. The modem is in Germany and I in the Netherland. why does it immediately connect to the dutch network?

@Florian-Duecker

No I have not. I set the registration to automatic not even to AT+COPS=1,2,“20416”. Do I have to set PLMN? even when connection is automatic

Hi,

With regular non-roaming connection the modems register almost instantly to the network. However when the connection is via roaming there is no connection to network. We Have SARA-N310 module that we have tested here in the Netherlands, everything was ok. The module is now in Germany with the same configuration and its not able to connect to the network? any idea why?
