I updated my HS2350 (rebranded h5321gw) to MBIM-enabled firmware R3C11
and tested it out.

The MBIM protocol does not give ModemManager the LAC/CI at all, so MM
can't actually tell you any of that.  And it's a bug in ModemManager
that it says MBIM devices actually have 3gpp-lac-ci capability; that
should be removed.

In the case of the Ericsson devices though, they still present an AT
port, so it's possible we could get that information via the AT port
while still controlling the modem with MBIM.  Unfortunately though,
that's not implemented.

If you can manage to flash it back to R1D08 or whatever is the pre-MBIM 
firmware, it'll get used as a normal "MBM" modem and that would allow
LAC/CI presentation.
