What are the MCC and MNC codes in Thailand?
Every mobile network in Thailand shares Mobile Country Code (MCC) 520 — the three-digit prefix that opens every PLMN broadcast by a Thailand SIM. The country's international dialling prefix is +66, which is distinct from the MCC: 520 identifies the country inside the network, while +66 routes voice calls. Under ISO 3166 Thailand is coded TH / THA / 764. This page lists 14 mobile networks across 15 PLMN codes operating in Thailand, with each network's MNC, full PLMN, operator, status and market share.
By reported market reach, the largest networks in Thailand are AIS (46.7%), AIS (46.7%), TrueMove H / my by NT (2.9%).
