I believe the generic plugin already harvests location area code and
cell ID whenever available in the AT+CREG? reply. Although I never tried
it myself, you can possibly use the GetLocation() method in the
org.freedesktop.ModemManager.Modem.Location interface (once enabled with
the Enable() method).
