eSIM Tonga: Tonga costs $3.15 a gigabyte at best, and unlimited data costs up to $95

What does eSIM Tonga cost on Airalo?

All the figures for eSIM Tonga here come from Airalo, and only from Airalo. We hold fourteen Tonga plans, each read off airalo.com on 8 October 2026. We have priced only Airalo for Tonga; we have not priced Saily, Holafly, Nomad, eSIMCard or eSIM Go here, so this eSIM Tonga list is one company's price list, not a survey of the market, and it cannot tell you the best eSIM for Tonga across sellers.

The cheapest gigabyte is $3.15, from the 10 GB plan over 7 days at $31.50. The dearest is $4.50, from the 1 GB plan over 3 days at $4.50. That is a 1.4-fold spread inside one seller's list. For other countries and sellers see the cheapest eSIM plans and how the providers compare.

The whole Tonga price list

Verified 8 October 2026. Every row is Airalo.

Unlimited plans exist: $27.50 for 3 days, $41.50 for 5 days, $53 for 7 days, $69 for 10 days, $95 for 15 days. The largest metered plan is 10 GB.

Which size should you buy?

The 10 GB plan is $31.50 for 7 days, $32.50 for 15 and $34 for 30, so the month costs $2.50 more than the week. Unlimited plans run from $27.50 for 3 days to $95 for 15 days; 15 days of unlimited costs $62.50 more than 10 GB over the same fortnight.

For a short trip with light use, the 1 GB plan at $4.50 over 3 days is the entry point, but at $4.50 a gigabyte it is among the worst rates here. If you will use real data for maps, messages and photos, the 10 GB range starts at $31.50 (7 days).

What to know before you buy a Tonga data plan

An eSIM Tonga purchase is only part of the picture. Travel guides say Airalo's Tonga eSIM (sold as Tofua Mobile) runs on the Digicel network, and that TCC, the Tonga Communications Corporation, also sells SIMs. One guide says ID is required to register a SIM by law. All of this is from travel sellers, and we could not confirm it on Digicel's or TCC's own sites. Airalo itself publishes no host network.

We have not tested these plans on a phone; this is desk research from public sources, and the data tells you what Airalo charges, not how fast or reliable a Tonga travel SIM will be in practice.

Is a cheap eSIM for Tonga worth it versus roaming or a local SIM?

We have not priced roaming from any home carrier, and we have not priced local SIMs for Tonga, so we cannot give you a verified saving. What the data supports is narrower: an eSIM can be installed before you leave and avoids a counter queue on arrival, and the price you will pay is on this page. Check your own carrier's daily roaming charge against the plan you are considering; whether a Tonga travel SIM from Airalo beats it depends on that figure, and we do not have it.
