How to handle roaming correctly?

[safesky-app]

When connected to a national network, how should we handle crossing the border and switch to another GSM provider?

• the documentation does not indicate any particular roaming setting: is by default an authorised SIM able to connect to foreign network?
• is it handled automatically by SIM7600, like with a mobile phone is somehow doing?
• or instead, should we detect by code that we have no network any more, and re-establish a new connection?

Thanks a lot advance,

Tristan

The SIM7600 will automatically switch to the operator that can connect to it, which is the same as the mobile phone. For applications, you need to check the network connection status when accessing the network
