The Maori and English-speaking islands are part of New Zealand but locals also have Cook Islands national status. BlueSky is the only phone operator available on the islands.

Rarotonga is the largest island and the main retail spot for purchasing prepaid SIM cards. There are 2G, 3G and 4G plans available, but you can only use their SIM cards in unlocked GSM phones. You can buy SIM cards without registering them, but some retailers will ask to see your passport and hotel address. Your telephone number will already be active when you purchase it. Few foreign operators offer roaming on the islands, so it’s best to purchase a local SIM card to avoid astronomical roaming rates.
