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

[Marcel]

Do you think it could help if I provide you another log of an execution 
of my script with specific parameters? Or should I go through my logs 
searching for specific parts? I'm not really sure what I should look for.

Is there anything I could do to stabilize the network switching? Maybe 
do some stuff between the connects? Or quickly restart the mm? Would it 
help to quickly stop the mm and then start again? Or is it even the 
modem which is busy, so the mm doesn't have to do anything with the error?
