Telecommunications in the Cook Islands is limited by the country's low population and isolation, like most countries and territories in Oceania. There is only one major television broadcasting station and six radio stations. However, most residents have a main line or mobile phone.
There is only one major television broadcasting station and six radio stations. However, most residents have a main line or mobile phone. Its telecommunications are mainly provided by Telecom Cook Islands, who is currently working with O3b Networks, Ltd. for faster Internet connection.
Radio Cook Islands was set up in the 1970s by the Government of the Cook Islands broadcasting on AM 630kHz. It uses a 5kW transmitter but this has had to be cut in half due to power costs. The station is heard all over Rarotonga, the Southern Group islands and in the Northern Group only by car radio's with wires strung between coconut trees.
However, most residents have a main line or mobile phone. Its telecommunications are mainly provided by Telecom Cook Islands, who is currently working with O3b Networks, Ltd. for faster Internet connection. Telecom Cook Islands was majority owned by Spark New Zealand until 2015, when it sold its interest to Teleraro Limited.
