The ITU-T Recommendation E.212 defines mobile country codes as well as mobile network codes. The mobile country code consists of 3 decimal digits and the mobile network code consists of 2 or 3 decimal digits (for example: MNC of 001 is not the same as MNC of 01). The first digit of the mobile country code identifies the geographic region as follows (the digits 1 and 8 are not used): * 0 - Test networks * 2 - Europe * 3 - North America and the Caribbean * 4 - Asia and the Middle East * 5 - Oceania * 6 - Africa * 7 - South and Central America * 9 - World-wide (Satellite, Air - aboard aircraft, Maritime - aboard ships, Antarctica) A mobile country code (MCC) is used in combination with a mobile network code (MNC) (also known as a "MCC / MNC tuple") to uniquely identify a mobile network operator (carrier) using the GSM (including GSM-R), UMTS, and LTE public land mobile networks. Some but not all CDMA, iDEN, and satellite mobile networks are identified with an MCC/MNC tuple as well. For WiMAX networks, a globally unique Broadband Operator ID can be derived from the MCC/MNC tuple.〔(【引用サイトリンク】url=https://standards.ieee.org/develop/regauth/tut/bopid.pdf )〕 TETRA networks use the mobile country code from ITU-T Recommendation E.212 together with a 10-bit binary mobile network code. However, a TETRA network may be assigned an E.212 network code as well. Some network operators do not have their own radio access network at all. These are called mobile virtual network operators (MVNO) and are marked in the tables as such. Note that MVNOs without their own MCC/MNC (that is, they share the MCC/MNC of their host network) are not listed here. The following tables attempt to provide a complete list of mobile network operators. Country information, including ISO 3166-1 country codes is provided for completeness. Mostly for historical reasons, one E.212 MCC may correspond to multiple ISO country codes (e.g. MCC 362 corresponds to BQ, CW, and SX). Some operators also choose to use an MCC outside the geographic area that it was assigned to (e.g. Digicel uses the Jamaica MCC throughout the Caribbean). ITU-T publishes an official list of mobile network codes from time to time in the Operational Bulletin.〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔 Unfortunately, the official list is often incomplete as national MNC Authorities do not forward changes to the ITU in a timely manner. The official list does not provide additional details such as bands and technologies and may not list disputed territories such as Abkhazia or Kosovo. == Test networks == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「mobile country code」の詳細全文を読む スポンサード リンク
