I can see the access tech changing a lot umts->gprs->unknown->umts... is
there good coverage? if there is an antenna, is it connected?

If you test this same exact setup with MM 0.6.x it ends up registered?

Wait, you didn't compile ModemManager with MBIM support, did you? MM is
explicitly ignoring the MBIM ports, and that can only happen if it
wasn't compiled with libmbim-glib support. You can get libmbim here:

Sigh... I wonder if we should just fully skip PH_SIM always.
