Network Usage Tips
remote island regions
Outer islands (such as Niuafo'ou) may only have 2G coverage, so it is recommended to download offline maps in advance.
During marine activities
Signal interruption occurs when diving or sailing offshore, and it automatically resumes upon returning to land.
Rainy season impact
From November to April, the rainy season may affect signal stability, so it is advisable to prepare alternative communication methods.
Price Evaluation
Tonga's mobile network coverage is available on major islands and towns, but signal is limited in outer islands and remote areas. Data plans are relatively expensive, so it's advisable to choose a suitable package based on trip duration and data needs, with multi-day plans offering better value for money.
