I also meant:

GetRegistrationInfo() -> (uss)

The returned arguments mean:
u - Registration status: Idle:Home:Searching:Denied:Unknown:Roaming
s - Registered operator code
s - Registered operator long name

Which would be the union of a lot of commands you proposed.

We're talking about the interfaces starting with
org.freedesktop.ModemManager.Gsm.* so CDMA can be ignored here.
