!!! Overview[1]
[{$pagename}] ([MNC]) is specified in [ITU-T] [E.212] is a three digit code (North America) or two digit code (Everyone else) that is used in combination with a [Mobile Country Code] ([MCC]) to identify a [Mobile Network Operator] uniquely

[{$pagename}] is used within:
* [Integrated Circuit Card Identifier] ([ICCID])
* [Home Network Identity] ([HNI])
* [International Mobile Subscriber Identity] ([IMSI])
* [Mobile Global Title] ([MGT])

!! North America
North America nominally uses three-digit [{$pagename}]s whereas the rest of the world uses two-digit [{$pagename}]. Due to this uniqueness, and a lack of support in international networks, carriers which are only uniquely identified via a three-digit [{$pagename}] are __NOT__ compatible with international roaming. As a result, in practice, most major [United States] carriers have MNCs ending in 0, so that they are uniquely identified by the first two digits, thereby providing their subscribers with compatibility on international networks.
