it is a known issue, you will notice in dmesg that the usb hub also restarts, my opinion is that is a power surge of the modem, though you can restore it either restarting eg25-manager or giving `ofonoctl online` and entering the PIN with the qdbus command, still Plasma dialer won't be able to make calls and the best way is to restart the phone. The problem could be temporarily fixed by writing some script that regularly checks the modem and restores it if it's down.
