More accurately:

* Public Land Mobile Network (PLMN) name; or
* Mobile Network name (shortened form of the above); or
* Service provider name (SPN) (as stored on the SIM).

Rules for display:

1. If Mobile Country Code (MCC) and Mobile Network Code (MNC) broadcast on
the network match the MCC and MNC on the SIM, the Service Provider Name (SPN)
on the SIM is displayed.

2. If the MCC-MNC combination does not match, the phone checks a table in its
firmware for an entry corresponding to the MCC and MNC received. If found,
that entry is displayed.

3. If no table entry is found, the country abbreviation (or the MCC if no
country name entry is found in firmware) and the MNC are displayed.
