ModemManager already supports this for generic GSM/UMTS devices.  If
your modem isn't handled correctly by the generic plugin then we should
fix up the generic plugin for quirks, or make a new plugin for your
modem.  But if all you need is AT+CREG then that's already covered.  I
assume you're just looking for LAC/CI, which I'll reply about in the
other mail in the "Modem initialization" thread.
