How to Buy a SIM Card in Tonga in 2026
Is there a good eSIM for Tonga? Honestly, not from us: none of our data bundles includes Tonga at a sensible price. The best way to get online is a local SIM from Digicel or TCC's U-Call, and both have booths at Fua'amotu International Airport, so you can sort it out within minutes of landing. A starter costs a few pa'anga. This guide explains which network to choose for which islands, what the cards and top-ups cost, and how to keep your home number reachable. Our plans are on the Tonga eSIM page.
Digicel or U-Call?
Tonga has two mobile networks. The choice depends on where you are going:
- Digicel has 4G on the main islands and, according to one guide, now has more subscribers than U-Call. But it is active only on the main islands, so the same guide advises against it if you plan to visit the smaller inhabited islands.
- U-Call, run by TCC, is the one usually recommended for remote areas. It has no 4G: its network is 2G and 3G only.
Staying on Tongatapu, around Nuku'alofa? Digicel's 4G is the faster option. Heading to Vava'u, Ha'apai or 'Eua, or further out? U-Call is the safer bet for signal, at slower speeds.
Buying at Fua'amotu Airport
Both U-Call and Digicel have booths at the airport, where buying a SIM takes a few minutes. Bring your passport: unlike most of Oceania, Tonga requires it when you buy a SIM card. One tourist guide warns that airport prices can be higher than at other outlets. U-Call cards are also sold in TCC stores and by vendors, and Digicel cards in Digicel stores.
Prices and top-ups
The figures come from travel guides and a trip report, not from the operators, so check them at the booth:
- Digicel SIM: free at the airport, or 5 TOP at a Digicel store, in one guide; a trip report gives 5 TOP for both networks.
- U-Call starter: 5 TOP, with 500 MB, 500 minutes and 500 texts.
- U-Call 5GB for two weeks: 15 TOP, in the trip report.
Once the starter runs out, top up at a TCC or Digicel store or a vendor, and ask for the data plans on offer at the time: they change often.
What we can offer
Two of our plans have a place on a Tonga trip, and one does not:
- O2 SMS Only, $8 a month: a private UK number that receives texts worldwide, so bank and booking codes keep arriving while your local SIM handles data. No data, no calls.
- Vodafone Travel VIP costs $32 and works in Tonga, but Tonga is one of its daily-fee countries: each day you use it there costs a further $7.50. It makes sense only if Tonga is a short stop on a longer trip through countries it covers without the fee.
- Global PAYG also appears on the country page, but its data in Tonga is very expensive, so we do not suggest it there.
Before you fly
Check that your phone is unlocked, or neither network's card will work in it, and keep your passport in your hand luggage for the airport booth. If you are flying on to the outer islands, buy your SIM on arrival at Fua'amotu, where both networks are in one place.
The options side by side
| Option | Price | Network and data | Where to get it |
|---|
| Digicel SIM | Free at the airport or 5 TOP (guides) | 4G on the main islands | Fua'amotu Airport booth, Digicel stores |
| U-Call starter | 5 TOP | 2G and 3G, wider reach; 500 MB included | Fua'amotu Airport booth, TCC stores, vendors |
| U-Call 5GB | 15 TOP | 5 GB for two weeks | TCC stores and vendors |
| Vodafone Travel VIP | $32 plus $7.50 a day in Tonga | Daily-fee country | Online, before you fly |
| O2 SMS Only | $8 a month | UK number for texts, no data | Online, before you fly |
Our recommendation
Buy a local SIM at Fua'amotu Airport with your passport: Digicel if you are staying on Tongatapu and want 4G, U-Call if you are visiting the outer islands. Add O2 SMS Only before you fly if you need your home codes. Our eSIM installation guide explains the set-up, and our plans are on the Tonga eSIM page.
