Current MM in Ubuntu fully ignores WWAN ports handled using the QMI protocol; which means the modem is stuck to use PPP over a serial port. That method seems to be enough for slower connections like GSM/HSPA, but definitely not for LTE.
The fix for this is to use QMI and the WWAN port, as done in current git master of MM :-/
