Let's find if there is a problem in KDE's editor/applet or in Networkmanager/ModemManager itself. What editor do you use for creating the connection profile, KDE one? Can you try with nm-connection-editor binary? Could you attach 'journalctl -b -u NetworkManager' logs?

Looks like this is an issue with KDE's connection editor. I was able to create a Mobile Broadband connection with nm-connection-editor. > Could you attach 'journalctl -b -u NetworkManager' logs? I have attached the logs since the point device was plugged in to the point where the status changes to registered.
