nextSIM eSIM Data Plans for Tonga

nextSIM does not provide truly unlimited data eSIMs for Tonga. The plans that carry the word “Unlimited” in their names actually include a fixed data allowance that is capped at 1 GB or 2 GB per day; once that limit is reached, the speed is reduced to 512 kbps or 2000 kbps, respectively. For travelers who need a high‑speed connection without such throttling, nextSIM offers fixed‑data options such as a 10 GB plan for 30 days or a 5 GB plan for 30 days, both delivered over 3G. These plans provide a set amount of high‑speed data and may be more cost–effective for most users.

nextSIM does not provide a Tonga eSIM that includes a phone number or SMS capability. Only data‑only plans are available from the provider for Tonga.

Travelers who need voice or messaging can use popular VoIP applications such as WhatsApp, Telegram, or iMessage, which work over the data connection offered by the eSIM.

nextSIM offers 12 single‑country plans for Tonga, with no multi‑country options available. The plans are split into 4 daily data cap offerings and 8 fixed data cap offerings, providing different usage structures for short‑term travelers versus those who prefer a set data allowance. Prices start around $37.20 and can rise to about $925.55, while data caps range from 1 GB to 10 GB, giving users a wide range to choose from depending on their travel needs.
