What are the MCC and MNC codes in South Korea?
Every mobile network in South Korea shares Mobile Country Code (MCC) 450 — the three-digit prefix that opens every PLMN broadcast by a South Korea SIM. The country's international dialling prefix is +82, which is distinct from the MCC: 450 identifies the country inside the network, while +82 routes voice calls.
