The surrounding smaller islands in Vava'u have 4G within 5-10 km of Neiafu but drop off further out. Ha'apai's Lifuka has some signal in Pangai town but is inconsistent. Remote Ha'apai islets are offline.
Our verdict on SIM cards in Tonga
Best for: Whale watchers in Vava'u, Nuku'alofa city visitors.
Tonga is comparable to Samoa in price and coverage quality. Both are a step up from Micronesia or Marshall Islands in tourist infrastructure but well below Fiji or New Zealand.
Activation & registration

Choose a plan before you buy

Insert and configure
Insert the nano-SIM using the ejector tool. Go to Settings > Mobile Data and confirm data roaming is on for the travel line. Run a speed test to confirm you are connected.
