Or another thought:

1) rmmod cdc_mbim
2) plug the modem in

then MM will detect it as a regular Ericsson MBM modem using AT
commands and you should be able to get LAC/CI and location info.  You
probably won't be able to start a data connection though, since these
devices do not provide the psuedo-ethernet port which ModemManager
requires for Ericsson MBM modems.
