The telco provider in Kiribati

There is only one main operator in Kiribati: ATH Kiribati. The network has gone through a strict approval process before being allowed to operate on the islands, and tries to offer the best deals available. Services have been tried and tested by both locals and travelers, and can be trusted. It is pretty safe to say that purchasing a local SIM card will most probably work out to be cheaper than using your home phone there.

Some top tips from staff:

  • Gilbertese is spoken on the islands. If you don’t know the language then you may want to download Google Translate onto your phone before you travel. English is also widely spoken.
  • Locals call a SIM card a “SIM” or “Card” or “Chip”.
  • Ask the SIM sellers to set up the SIM for you, because they will know how to do it. If not, follow the instructions we have highlighted above or go to the official operator website to seek advice.
  • Get to the stores early to beat the crowds.

TripAdvisor tips for the best SIM cards and where to buy them

While it’s well known for reviews, booking hotels, flights and holidays, TripAdvisor also has many user comments that can help guide you through which SIM cards have been tried and tested in Kiribati.

Here are some top tips from TripAdvisor users:

Most overseas companies don’t cover Kiribati in international roaming. What we have done in the past is just buy a TSKL SIM card over there and use it in an Australian phone as long as the phone is unlocked.

“Most hotels have Wi-Fi, so if you don’t want to use a local SIM card you can take advantage of free connectivity in most places on the islands.”
