The best eSIM for Saint Barthélemy in 2026. Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Saint Barthélemy, priced on the same day: two weeks unlimited for $18.99, a month for $28.99.
Prices read on 28 September 2026. Six travel eSIMs sell data for Saint Barthélemy, St Barts to most visitors, and get most of the traffic for this search. We priced all six on the same day, for a long weekend in Gustavia, a week on the beaches, two weeks and a month, and read the fine print on unlimited. The island is French but outside the EU, so an EU phone plan does not cover it by law. Here is where each one wins.
Ringo Light: Cheapest unlimited for a week, two weeks or a month. Unlimited data at full speed for 2 weeks at $18.99 or 30 days at $28.99, one payment each, nothing renews. Airalo asks $65 for 15 days and $99 for the month.
Ubigi: Cheapest small plan, and the cheapest 10 GB that lasts a month. 3 GB for 15 days at $8 on its Saint Barthélemy plan, and 10 GB for 30 days at $19 on its Best Caribbean regional plan.
Nomad: Most data for the money over a month. 50 GB for 30 days at $39 and 20 GB at $33, on Digicel. Nomad sells no unlimited here.
Airalo: Cheapest 3 days of unlimited. $19.50 on Digicel, 3 GB a day at full speed, then 1 Mbps. Holafly is 40 cents more. Our 2 weeks costs 51 cents less than either, but it is not a 3-day plan.

Most people come to Saint Barthélemy for a week or two of beaches, boats and dinners in Gustavia. Some stay a season, for work in the villas, hotels and yards. Data here is dear: for 15 days of unlimited, Airalo asks $65 and Holafly $66.50. Ubigi's Caribbean regional plan, which covers the island, asks $75 for 30 GB at full speed, then 2 Mbps. Saily and Nomad sell no two weeks of unlimited. Ringo Light charges $18.99 for 2 weeks, one payment, nothing renews.
For a month the gap is wider. Saily's Global plan costs $59.99 for 30 GB at full speed, then slowed. Ubigi's Best Caribbean month is $69 for 60 GB, Airalo $99 and Holafly $133.50. Ringo Light charges $28.99 for 30 days.
Read what unlimited means before you pick. Airalo gives 3 GB a day at full speed, then 1 Mbps. Ubigi and Saily give a fixed amount, then slow you down. Holafly states no daily cap for your own phone and limits sharing to 1 GB a day. Ringo Light has no speed cap: the 2 weeks starts with 10 GB and the 30 days with 20 GB, and when you have used 80% we add 10 GB once and charge the $18.99 top-up. A heavy two weeks with us costs $37.98, still well under every rival's two weeks. A heavy month costs $47.98 for 30 GB, still under every rival's unlimited month, but Nomad sells 50 GB for 30 days at $39. If you know you will use more than 30 GB in a month, Nomad's 50 GB is the better buy.
For a short trip, Ringo Light sells no 3-day or 7-day plan. Airalo sells 3 days of unlimited at $19.50 and Holafly at $19.90, so on this island our 2 weeks at $18.99 costs less than either brand's 3 days. For a week, Airalo asks $36, Holafly $36.50 and Ubigi $27 for 20 GB at full speed on its Best Caribbean plan.
Saint Barthélemy is small and steep, and the travel eSIMs here name one network: Airalo, Holafly and Nomad all ride Digicel. Saily and Ubigi do not name theirs on their listings. Holafly's own page says coverage covers most populated areas and beaches, and may be weaker in secluded coves, on high ground, on some boat trips, and in parts of the Colombier, Gouverneur and Saline beaches. Download offline maps before you walk to Colombier or drive out to the south coast.
The island is French and uses the euro, but it left the European Union on 1 January 2012 and is now an overseas country and territory associated with it. The EU roaming rules, roam like at home, apply only inside the EU, so they do not cover Saint Barthélemy. Whether a French or other EU plan includes it is up to the operator, so read your plan's price list before you fly. A Europe travel eSIM does not cover it either; our Europe trip does not.
Ubigi, $8 for 3 GB. Its Saint Barthélemy plan, 3 GB for 15 days, the cheapest way to cover a short stay. Its Best Caribbean regional plan sells 10 GB for 30 days at $19 and 3 GB for 30 days at $9.
Nomad, $23 for 10 GB. 20 GB for 30 days at $33 and 50 GB for 30 days at $39, the most data for the money here, on Digicel. 3 GB for 30 days is $12. Nomad sells no unlimited for Saint Barthélemy.
Airalo, $39 for 10 GB. Its Barnet plan: 20 GB for 30 days at $49 and 5 GB at $27. The app is needed.
Saily, $45.99 for 10 GB. Its Saint Barthélemy plan; 5 GB is $33.99. Its listing is from July; saily.com would not load for us.
Ringo Light, no buckets. Our 2 weeks starts with 10 GB for $18.99, one dollar and one cent under Ubigi's 10 GB, but Ubigi's lasts 30 days and ours 2 weeks. Our 30 days starts with 20 GB for $28.99, under Nomad's 20 GB at $33, but Nomad's 50 GB at $39 gives far more data for a month. For 3 GB, Ubigi at $8 and Nomad at $12 cost less than anything we sell. We would rather you read that here than at checkout.
Ringo Light is our own data eSIM, sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Saint Barthélemy it sells two trips, both unlimited data at full speed with no speed cap: 2 weeks at $18.99, starting with 10 GB, and 30 days at $28.99, starting with 20 GB. Each adds 10 GB once at 80%, charged at $18.99. One payment, nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
Our Caribbean trip and our Europe trip do not cover Saint Barthélemy, so this is the Ringo Light to buy for it. It covers Saint Barthélemy only, not Saint Martin, Sint Maarten or Anguilla, where most flights and ferries connect.

Your phone plan is from France or another EU country. Check your price list first. Saint Barthélemy is outside the EU, so roam like at home does not apply by law.
You need your own number to keep ringing. None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
What to do in Saint Barthélemy, and what your phone needs for it. Eight places most first trips include, from the harbour at Gustavia and the famous runway at Saint-Jean to the beaches at Colombier, Saline and Flamands, with the one thing your data does for you at each. The island is small enough to cross in a short drive, but the roads are steep and the signal thins in the far coves.
Gustavia, The harbour town. The capital, a harbour of red roofs and yachts, named after a Swedish king: the island was Swedish for almost a century before France took it back in 1878. Walk the quays and the streets behind them in the morning, before the heat. There is no ride-hailing app on the island to count on. Save a taxi number in your phone, or book a hire car before you land.
Fort Gustave and the harbour view, Above Gustavia. The remains of a Swedish fort on the hill over the harbour, next to the lighthouse, with the whole of Gustavia below. Go late in the afternoon for the light. Ferries to Saint Martin leave from the harbour below. Keep your ticket and the departure time on your phone, and remember a Saint Barthélemy plan may stop working when you land there.
Saint-Jean Bay, Saint-Jean. The island's busiest beach, a curve of sand with the Eden Rock on its rock and shops and cafés along the road behind. The water is calm and shallow for swimming. Prices are in euros and cards work as in France. Your bank app shows the conversion if you pay from a dollar or pound account.
The runway at La Tourmente, Saint-Jean. Small planes drop over the hill at La Tourmente and land on a short runway that ends at the beach. The roadside on the hill is the classic place to watch. Flights are small and depend on the weather. A flight tracker shows the next landing, and your airline's app any change to your own.
Anse de Colombier, The north-west tip. A beach with no road to it: you walk a coastal path from the end of the road at Colombier, or come by boat. Holafly names Colombier as a place where signal may be weak. Download the offline map before you set off on the path.
Anse de Grande Saline, The south coast. A long, wild beach behind a dune near the old salt ponds, with no hotels on the sand. Bring water and shade: there is little there. Signal may be weaker on this beach too. Check the weather and the wind in a forecast app before you drive out.
Anse des Flamands, The north coast. A wide beach of white sand on the north coast, quieter than Saint-Jean, with a few hotels set back behind it. The sea here can have waves when the wind is from the north. A forecast app with wave height tells you whether to swim here or cross to the calmer south side that day.
Corossol, West of Gustavia. A small fishing village on the bay west of Gustavia, where boats lie at anchor below the houses and the island's older ways hold on. Stop on the way between Gustavia and Colombier. The roads out here are narrow and steep. A live map keeps you on the right one and shows where you can park.
We priced Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Saint Barthélemy on 28 September 2026, all on the same day, in US dollars. Each rival's price comes from its own website where it showed dollars, otherwise from an esimdb.com listing, and every source and its date is listed below. Ringo Light's prices come from the catalogue our checkout charges.
We compare the trips people actually book: a week, two weeks and a month of unlimited data, and a 10 GB bucket. We read each brand's fair use and speed rules and quote them as the brands state them. We did not run speed tests, so this page makes no speed claims for any brand.
Ringo Light is our own product. We put it in the table on the same terms as everyone else, and where a rival is the better buy the page says so.
Left out: Maya Mobile, we could not read its own prices for this country on the day, so it stays out rather than being guessed.

For a week, two weeks or a month of unlimited data, Ringo Light: $18.99 for 2 weeks and $28.99 for 30 days on 28 September 2026, against $65 for 15 days and $99 for 30 days at Airalo. For 3 days of unlimited, Airalo at $19.50. For a small plan, Ubigi at $8 for 3 GB. For 10 GB that lasts 30 days, Ubigi at $19; for the most data in a month, Nomad at $39 for 50 GB.
Airalo, Holafly and Nomad all name Digicel. Saily and Ubigi do not name their network on their listings. Holafly says coverage may be weaker in secluded coves, on high ground and in parts of the Colombier, Gouverneur and Saline beaches.
Every brand has a limit somewhere. Airalo slows you after 3 GB a day, Ubigi and Saily after a fixed full-speed amount. Holafly states no daily cap for your own phone. Nomad sells no unlimited here. Ringo Light has no speed cap: it starts with 10 or 20 GB and adds 10 GB once at 80%, charged.
Not by law. Saint Barthélemy is French and uses the euro, but it left the European Union on 1 January 2012 and became an overseas country and territory, so the EU roam like at home rules do not apply there. Some operators may still include it in a plan, so read your price list before you fly. Guadeloupe and Martinique, by contrast, are in the EU. A Europe travel eSIM does not cover Saint Barthélemy either; our Europe trip does not.
