Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Status changed to 'Confirmed' because the bug affects multiple users.

I've backported usb-modeswitch 2.4 and usb-modeswich-data 2017-01 from Ubuntu 17.04 (Zesty) to 16.04 LTS (Xenial), you can update packages from ppa:baltix-members , see
https://launchpad.net/~baltix-members/+archive

Please reboot after installing usb-modeswitch 2.4 and usb-modeswich-data 2017-01 from ppa:baltix-members , test if your USB modem works correctly with updated packages and write a comment here in any case (works or not).

Thanks,
