Forget the mm, I think in this case only nm is involved. Or do just a simple dhclient to the interface.

ModemManager 1.4.8-1
NetworkManager 1.0.2-3

On OpenSUSE the device does throw up a new Network Interface but on RPi-2 it
doesn't that's the problem. 

Maybe I should look for another Dongle which uses CDW

Been on a few times between this list and the ModemManager. I was hoping to 
setup a system where I could build some intelligence behind two USB 4G Dongles 
and jump between connections depending on signal strength. 

My second Dongle has stopped that, as it don't report as a Modem device and 
instead uses Ethernet over USB. This all works out of the box on my OpenSUSE 
Laptop but the RPi-2 doesn't work. 

On the laptop "usb-devices" is giving me: 

What's the 'lsusb -v -d 19d2:1403' output?

In both cases the output is more or less identical except for this diff:
