What are the MCC and MNC codes in Slovakia?
Every mobile network in Slovakia shares Mobile Country Code (MCC) 231 — the three-digit prefix that opens every PLMN broadcast by a Slovakia SIM. The country's international dialling prefix is +421, which is distinct from the MCC: 231 identifies the country inside the network, while +421 routes voice calls. Under ISO 3166 Slovakia is coded SK / SVK / 703. This page lists 10 mobile networks across 12 PLMN codes operating in Slovakia, with each network's MNC, full PLMN, operator, status and market share.
