What are the MCC and MNC codes in Singapore?
Every mobile network in Singapore shares Mobile Country Code (MCC) 525 — the three-digit prefix that opens every PLMN broadcast by a Singapore SIM. The country's international dialling prefix is +65, which is distinct from the MCC: 525 identifies the country inside the network, while +65 routes voice calls. Under ISO 3166 Singapore is coded SG / SGP / 702.
