Prepaid Data SIM Card Wiki



The Australian external territories are small island territories in the Indian and Pacific Oceans attached to Australia, but not served by Australian operators:

  • Christmas Island
  • Cocos (Keeling) Islands
  • Norfolk Island

This is added with information about:

  • Macquarie Island in Antarctica
  • Lord Howe Island in the Tasman Sea

These islands used to be without major internet connections. This has changed since the Australian Government installed nbn Sky Muster satellite services to cover remote areas in 2015-8. Sky Muster has improved connectivity to these islands a lot as 4G/LTE networks are being deployed.

The availability of SIM cards to travellers is still quite new on some islands and 4G coverage typically only cover certain parts of the Islands. That's why these territories were moved from our Blacklist to our Greylist. You still might think of using a satellite phone to be sure of connection.

Christmas Island[]

Christmas Island is located in the Indian Ocean, around 350 km south of Java and Sumatra and around 1,550 km north-west of the closest point on the Australian mainland. It has an area of 135 sq km and a population of 1,800 residents.


CiFi is a locally based & supported telecommunications company and is the primary provider of internet & mobile services in Christmas Island since 2020. CiFi is also the only provider to exclusively use the Vocus ASC subsea cable for backhaul, providing to the community & tourists high speed, low latency internet services which are available in many locations throughout the island.

CiFi's 4G/5G mobile network is the only one in operation on the island, and is also the largest, servicing areas both in the township & well out into the jungle areas.

Speedcast withdrew all services from the Christmas Island market in 2021.

Telstra 2G[]

Telstra also provides limited cellular coverage on Christmas Island, restricted only to the developed (small town/residential/airport) areas of the island. There is zero coverage within the national park itself, on the hiking trails and at the beaches. This is a 2G 900 MHz mobile network operated by Telstra that can only be used for voice and SMS with no mobile data coverage. Free wifi on the island is limited to the airport (only on flight days) although most hotels have included WiFi that runs over NBN satellite connections.

This situation was expected to improve in 2019 when the branch off to the INDIGO-West submarine cable was completed linking the Christmas Islands to Perth however due to the high transfer rates only a handful of government connections use the new link with no residential services offered.
