I'm almost done with checking the connection state using a proto_run_command with a simple script running uqmi --get-data-status periodically. If the check fails, the script dies and netifd should restart the connection. Then we hopefully don't need autoconnect anymore.

That's an interesting talk, thanks for the note!
