I was thinking of doing that, creating profiles
modem12345.nmconnection
modem22334.nmconnection
modem556677.nmconnection
etc...

But grabbing
IMSI=$(mmcli -m XX| awk /operator id/ ...)
and calling
nmcli c do-stuff modem$IMSI
seems to be the wrong way to use NetworkManager.

That might work. If I can put my own apns and passwords in the
mobile-broadband-provider-info file I'd get the same result.
I guess I could just play around with the patches a bit.
