I'm tending to agree, which is why I wanted to start the conversation.
By the way, just so that we're all clear, here's the relevant quote from the
standard:
"
MCC, Mobile country code (octet 2 and 3)
The MCC field is coded as in ITU-T Rec. E212, Annex A.
MNC, Mobile network code (octet 3 bits 5 to 8, octet 4)
The coding of this field is the responsibility of each administration but BCD
coding shall be used. The MNC shall consist of 2 or 3 digits. For PCS 1900 for
NA, Federal regulation mandates that a 3-digit MNC shall be used. However a
network operator may decide to use only two digits in the MNC in the LAI over
the radio interface. In this case, bits 5 to 8 of octet 3 shall be coded as
"1111". Mobile equipment shall accept LAI coded in such a way.

About the only thing that MCC/MNC is useful for is to display it during manual
operator selection. MCC/MNC is not helpful at all for countries like U.S.
with 4+ timezones and the same carrier id across all of them. A country
property would work just as well for this. What standard do we want to use
here? ITU 212? ISO 3166? or E164?
Any objections from actually removing the MCC/MNC Properties?
