The 3607GW based modems are well supported by oFono, however we have not
tested all of the possible ones.  So assuming that you have installed
ofono.rules file correctly the only other problem might be that your
device manufacturer has named the port / network devices slightly
differently from other manufacturers.

See plugins/udev.c add_mbm() for more details.  I see that we definitely
do not cover the "Broadband Network Device" case that your modem is
reporting.

Running ofono with -n -d 'udev*' command line options should help you
quickly diagnose the issue.

Regards,
