Where to buy a SIM card in Cook Islands
The best place to buy is Bluesky Cook Islands or Vodafone store in Avarua, Rarotonga. Here is what each channel offers and what to expect.
Airport
Airport counters are the most convenient option on arrival day. Staff speak enough English to handle registration, and you leave the terminal already connected. Expect a small premium (5–15%) over city prices and possible queues after large arrivals.

Official carrier stores carry every plan, can troubleshoot activation on the spot, and have English-speaking staff in tourist-heavy areas. Prices match the carrier website.
Buying experience
The Bluesky counter in Rarotonga International Airport arrivals hall is open on international flights. No passport registration required. Pay in NZD. Activation immediate. Vodafone has a store on the main road through Avarua, about 10 minutes from the airport. Both brands have top-up cards at supermarkets and fuel stations around Rarotonga.

Bluesky Cook Islands leads on overall coverage with a rating of 3/5 for reach and 3/5 for speed. In cities, all providers perform similarly. Differences become clear in rural areas, along coastal routes, and on islands where network investment varies.
Real-world connectivity
Rarotonga has excellent 4G from both Bluesky and Vodafone. The ring road around the island has full coverage. Inland highland areas lose signal in the dense forest. The cross-island track drops signal in the valley. Aitutaki atoll has 4G in Arutanga village and most of the main island. The motu (small outer islets) in the lagoon have patchy signal. Atiu, Mauke, and Mangaia in the Southern Group have basic coverage in their main villages. Northern Group atolls: Penrhyn, Rakahanga, Manihiki, and Pukapuka have either satellite-only or minimal mobile coverage.
