The short answer
Six travel eSIMs get most of the traffic for this search, and all six sell something that works in Tonga. I priced them on the same day, for a week on Tongatapu, two weeks with a hop to Vava'u or Ha'apai, and a month, and I read the fine print on unlimited. In Tonga Ringo Light is cheapest for two weeks and a month of unlimited, by a few dollars, and I say plainly who wins the short trips and the data buckets.
Unlimited data at full speed for 2 weeks at $45.99 or 30 days at $68.99, nothing renews. That is $3.01 less than Airalo's Oceania plan for 15 days ($49) and $4.51 less for 30 days ($73.50).
Its Oceania plan, which covers Tonga: 3 days of unlimited at $11.50, 15 days at $49, 30 days at $73.50, with 3 GB a day at full speed, then 1 Mbps. 10 GB for 30 days at $25.50 and 20 GB at $49. Its Tonga plan on Digicel costs more.
Its Best World plan, which covers Tonga: 60 GB at full speed for 30 days at $108, then 2 Mbps. 30 GB for 15 days at $77. Its own Tonga plan is 3 GB for 15 days at $34.
Days, not gigabytes, on Digicel: $28.50 for 3 days, $54.90 for a week, $104.50 for 15 days. Sharing limited to 1 GB a day; the longest plan is 20 days.

US dollars, read 31 October 2026 (Ubigi and the Airalo buckets as last read, 28 September). Ringo Light sells 2 weeks, the others 15 days. Airalo's Oceania plan gives 3 GB a day at full speed; Ubigi's Best World gives 30 GB, then 2 Mbps.
The 30-day plan at each brand that sells one. Ringo Light is unlimited data at full speed. Ubigi's month is 60 GB at full speed, then 2 Mbps. Holafly stops at 20 days.
Holafly sells no buckets and Saily's largest Tonga size is 5 GB. Ringo Light sells no bucket either: its 2 weeks is unlimited and lasts 2 weeks, not 30 days.

What to do in Tonga, and what your phone needs for it
Eight places most first trips include, from Nuku'alofa and the coast of Tongatapu to 'Eua, Ha'apai and Vava'u, with the one thing your data does for you at each. Tongatapu has good 4G; the outer islands have less, so plan the offline maps before you fly or sail.
If you want unlimited: Ringo Light, and where Airalo wins
Most people give Tonga one to two weeks: Tongatapu first, then a flight or a ferry to Vava'u, Ha'apai or 'Eua. For about two weeks of unlimited, Airalo's Oceania plan asks $49 for 15 days, Ubigi's Best World $77 for 30 GB, Airalo's Tonga plan $95 and Holafly $104.50. Ringo Light charges $45.99 for 2 weeks, $3.01 less than Airalo's Oceania plan. For a month, Airalo's Oceania plan is $73.50 and Ubigi's Best World $108 for 60 GB; Ringo Light is $68.99, $4.51 less than Airalo. For a short trip or a data bucket, Airalo is the cheaper one, and that is where I would buy from Airalo.
Read what unlimited means before you pick. Airalo gives 3 GB a day at full speed on both its plans, then 1 Mbps, which is more than most visitors use in a day on islands where you spend it on boats and beaches. Ubigi gives 30 GB for 15 days or 60 GB for the month, then 2 Mbps. Holafly states no daily cap for your own phone and limits sharing to 1 GB a day. Ringo Light is unlimited data at full speed for 7 days, 2 weeks or 30 days. For two weeks or a month in Tonga, my pick is Ringo Light.
For a short trip, Ringo Light sells no 3-day plan; its 7 days is $27.99. Airalo's Oceania plan sells 3 days of unlimited at $11.50 and a week at $27, which is $0.99 less than Ringo Light's 7 days.
Digicel, the outer islands, and one cable
Tonga has two mobile networks, Digicel and TCC, which sells as U-Call. Every travel eSIM here that names its network names Digicel. Nuku'alofa, the rest of Tongatapu and the main towns of Neiafu on Vava'u and Pangai on Ha'apai have 4G. Holafly itself warns that coverage gets weaker on the small Ha'apai islands, around the outer Vava'u islands, on the trails of 'Eua and on the boats between them. Save offline maps before you leave Tongatapu. I would not choose a plan by network here, since the named ones all use Digicel.
Almost all of Tonga's internet reaches the country through one undersea cable. When the Hunga Tonga eruption cut it in January 2022, the country was offline for weeks. That is rare, but it is why a local number for texts and a paper note of your bookings are worth having on the outer islands. I would take both.
Sunday is a day of rest by law in Tonga. Most shops, cafés and businesses close, so buy what you need on Saturday.
If you want a data bucket: Airalo's Oceania plan
- Airalo, $25.50 for 10 GB. Its Oceania plan for 30 days, and 20 GB at $49. Small sizes too: 1 GB for 3 days at $4.50, 5 GB for 30 days at $15.50. Its Tonga plan on Digicel sells 10 GB at $34. The cheapest data for Tonga at every size. The app is needed.
- Ubigi, $39 for 10 GB. Its Best World plan for 30 days. Its own Tonga plan is 3 GB for 15 days at $34, on Digicel Pacific.
- Nomad, $49 for 10 GB. A Tonga plan on Digicel for 30 days, with 1 GB for 7 days at $9, 3 GB at $19 and 5 GB at $29.
- Saily, $18.99 for 5 GB. Its largest Tonga size, for 30 days, with 1 GB for 7 days at $4.99. Its listing is from May; saily.com would not load when I tried.
- ✓Ringo Light, no buckets. Ringo Light's 2 weeks is unlimited for $45.99 and its 30 days unlimited for $68.99. For a fixed amount of data, Airalo, Ubigi and Saily are cheaper in Tonga, and Nomad's 10 GB at $49 costs $3.01 more than Ringo Light's 2 weeks of unlimited. I would buy Ringo Light for unlimited with no speed cap, not for a bucket.
What Ringo Light is
Ringo Light is Ringo's own data eSIM, sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Tonga it sells three trips, all unlimited data at full speed with no speed cap: 7 days at $27.99, 2 weeks at $45.99 and 30 days at $68.99. Nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
In Tonga Ringo Light's unlimited is the cheapest, by $3.01 for two weeks and $4.51 for a month against Airalo's Oceania plan. Airalo's Oceania plan is the better buy for a short trip or a data bucket, and Ubigi's Best World if you want a large amount at full speed. I would pick them for those trips. None of Ringo's regional trips covers Tonga, so there is no cheaper Ringo Light route in.
The card to buy it is further up this page, just after the side-by-side table.
