Planning a trip to Tonga and wondering what is the best way to stay connected? There are a couple different options when traveling to Tonga and I will explain them all in this Tonga sim card guide. Find out where to buy a sim card in Tonga, up to date prices as per June 2024, the best 4G/5G network in Tonga, my recommendation and info about international and e-sim cards for Tonga.

When traveling abroad the first thing I do is buying a prepaid sim card on arrival. It is the best best way to stay connected. E-sim cards are a great option too, but more expensive. If you use a lot of data, a local prepaid sim card is the cheapest way to stay connected.

My recommendation

Traveltomtom recommends a UCall sim card for Tonga. Prices for data sim cards are similar to Digicel, but UCall has the better mobile data network coverage across the country.

Another great option for travelers is an international sim card that includes Tonga. Also handy when you travel to several countries on your trip in the Pacific. Check out my comparison of the best international sim cards with data in 2024.

Best e-sim cards for Tonga

The easiest way to stay connected when traveling to Tonga in 2024 is an e-sim card. No more swapping physical sim cards or visiting a phone shop. You arrange everything online within just a couple minutes.

Why buying a sim card for Tonga

buying sim card in tonga

Life simply gets much easier when you are connected to the internet and that also counts for traveling in Tonga. Getting directions from Google Maps, finding nearby restaurants or tourist attractions, keeping in touch with friends and many more reasons to stay connected when traveling.

And of course to avoid high roaming costs or slow overseas data plans that promise you unlimited data for a couple dollars a day, but the data speed is reduced to the bare minimum and hardly works.

Where to buy a sim card for Tonga

where to buy sim card for tonga

The easiest place to buy a prepaid sim card is of course on arrival at the International Airport of Fua'Amotu on the main island of Tongatapu where you can also find the capital of Nuku'Alofa.

This is also where I landed on my trip to Tonga and where I bought my sim card for Tonga. As soon as you walk out of the airport you will see on your right hand side a store of UCall and Digicell, they can't be missed as these are basically the only two shops besides a car rental and money exchange.

Unfortunately the sim card stores do not accept international credit cards, it is cash only. Luckily there is an ATM at Fua'Amotu Airport. The sim card shops are open for all arriving international flights.

You can also buy a sim card for Tonga in the city of Nuku'Alofa at a UCall or Digicel store. They are located in the city center not far from the popular Friends Cafe, which is one of my travel tips for Tonga.

Registration process

For buying a sim card in Tonga you will need your passport for registration. In the phone shop they will take a copy of your passport and your new Tonga sim card will be registered on your name and passport number.

Best 4G/5G network in Tonga in 2024

Normally I compare the network coverage maps of all the mobile internet operators, but in the case of Tonga that is not possible as there are no network coverage maps available. To determine the best mobile internet network in Tonga I can use my own experiences and the advices from locals.

When we traveled to Tonga we were with 4 people and to find the best sim card for Tonga we decided that 2 people would buy a UCall prepaid sim card and the others a Digicel prepaid sim card, so we could compare. 

Unfortunately we only traveled on the main island of Tongatapu as we just had 3 days. We rented a car and drove around the island visiting all the tourist attractions. All 4 of us were constantly connected and enjoyed a 4G signal. Most of the times the data speed was good and there were no major issues for both Digicel and UCall.

So when traveling to Tonga and only exploring the main island of Tongatapu it does not matter which sim card you use.

That said when traveling to Vava’u for the famous whale watching/swimming in the North of Tonga local people all recommend buying a sim card from UCall. As UCall is the prepaid sim card of the state owned TCC (Tonga Communications Corporation) they have the most extensive network across the country. So when traveling to Vava’u a UCall sim card is recommended.

Is there 5G in Tonga?

No, as of June 2024 there is no 5G in Tonga. The data speed on the 4G network in Tonga is reliable and fast enough for streaming and uploading large files. Based on my own experience, everything worked pretty smooth.

Best sim card for Tonga in 2024

As there are no international sim cards available for Tonga, travelers can only choose between a local prepaid sim card for Tonga or an e-sim card. The cheapest e-sim card cost $9.50 USD and only gives you 1 GB data for 7 days. For 6 GB data you already pay $39.90 USD. 

A local prepaid sim card for Tonga is much cheaper and for $10 USD you can already 7 GB data for 30 days with a local prepaid sim card.

Comparing the Digicel and UCall prepaid sim card deals we come to the conclusion that there is not much difference in price, however Digicel is a little cheaper or gives you more GB's for the same price.

Based on my own experience there is also not much difference when it comes to the 3G/4G network strength, at least on the main island in Tongatapu.

However, TCC, the mother company of UCall owns the 3G/4G network in Tonga, UCall has better network coverage than Digicel around the country and is therefore the best sim card for Tonga in 2024.
