ModemManager cant create a broadband connection. On Fedora 26-64Bit, kernel 4.11.11. It detect modem, but after initialising connection, it reset, and display no message.
We'll need *a bit more* information :) Could you please gather NetworkManager and ModemManager debug logs while testing it? See https://www.freedesktop.org/wiki/Software/ModemManager/Debugging/
