trying to connect to different operators using --3gpp-register-in-operator

Yes, I'm using the simple-connect function with a 15 sec timeout.
The first operator 26201 connects without any problems at all, then when 
disconnecting and connecting to 26202, the first, maybe also the second 
try to simple-connect fails. But then when I disconnect again from 26202 
and try to connect to 26203 again it just won't connect.
It seems like the mm is still busy doing some other stuff in the 
background.
At the end of my script, I disconnect again and disable the modem. 
Disconnecting works fine, but the modem doesn't disable, but seems to 
hang on state 'disabling'. Around 1 minute after my script finished the 
mm seems to be done with its background stuff and disables the modem.

Well I just tried a script setup with 8 tries to connect each with a 50 
seconds timeout, same result, operators 26201 and 26202 worked 
perfectly, 26203 didn't succeed at any of the 8 connect attempts.
I also tried a setup with a 15 seconds timeout and a 60 second sleep 
between each operator with the same result.
And right now I tried a setup where I also used the 
3gpp-register-in-operator function, but that didn't work either.
Weell about the reproduction with AT commands: I'm don't really know 
which commands I would have to use, I already thought about just doing 
the whole script with AT commands, but then I recognized that it's a lot 
more complicated than I thought and so I just used mmcli which already 
is very simple and efficient.
So about that, I'm sorry, but no, I unfortunately can't reproduce the 
issues, sorry.
