I don't mind adding more information like marking WAP APNs, per-APN
proxies, SMS center, MMS, etc.  We'll need to extend the schema but
that's easy enough.

WRT substituting provider names in COPS responses when the modem doesn't
have the name, the best I think we can do is back-map the MCC/MNC to a
list of providers, or query the SIM for more correct information.
