I meanwhile had issues again and I'm now running on ppp. It behaves ok
until it doesn't, so somehow the issues are back here as well. I am
currently logging quite a lot so let's see what I figure out.

ppp seems nice, I especially like pppctl to see status of the line.

What I can't seem to figure out is how to send AT commands like
AT!GSTATUS? on "demand" to the modem with pppctl, any ideas of how this
would look like?

Can't seem to find much on the topic, I think ppp & AT is a bit out of
fashion for most.

I see the GSTATUS in the log on startup but I would like to check
frequency bands from time to time to see if it stays on the same or not.
