The best eSIM for Saint Martin in 2026. Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Saint Martin, 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 Martin, the French side of the island, and get most of the traffic for this search. We priced all six on the same day, for a long weekend, a week between Grand Case and Orient Bay, two weeks and a month, and read the fine print on unlimited and on the Dutch side. Saint Martin is part of France and the EU, so an EU phone plan may already cover you. Here is where each one wins.
Ringo Light: Cheapest unlimited for 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 $49 for 15 days and $73 for the month.
Airalo: Cheapest 3 days, tied with Holafly. 3 days of unlimited at $12.50 on Digicel, 3 GB a day at full speed, then 1 Mbps. Holafly asks the same $12.50.
Ubigi: Cheapest 10 GB that lasts a month. 10 GB for 30 days at $19 on its Best Caribbean regional plan, on Digicel and Orange Caraïbe, and 3 GB for 15 days at $8 on its Saint Martin plan.
Nomad: Most data for a heavy month. 50 GB for 30 days at $39 and 20 GB at $33 on its Saint Martin plan. Nomad sells no unlimited here.

Most people stay on Saint Martin for a week or two: a villa or a hotel on Orient Bay or in Grand Case, dinners on the boulevard, a boat to Pinel, a day on the Dutch side. For 15 days of unlimited, Airalo asks $49 and Holafly $50.50. Ubigi's Caribbean regional plan 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 1 Mbps. Ubigi's Best Caribbean month is $69 for 60 GB, Airalo $73 and Holafly $73.90. 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 under every rival's two weeks. A heavy month costs $47.98, under every rival's unlimited month. If you already know you will use more than 20 GB in a month, Nomad's 50 GB for 30 days at $39 costs less than that heavy month with us.
For a short trip, Ringo Light sells no 3-day or 7-day plan. Airalo and Holafly both sell 3 days of unlimited at $12.50. For a week, our 2 weeks at $18.99 costs less than any rival's 7 days: Airalo and Holafly ask $27.50, and Ubigi $27 for 20 GB at full speed on its Best Caribbean plan.
Saint Martin is the northern, French half of an island it shares with Sint Maarten, a country of the Kingdom of the Netherlands. There is no border control between them, and most visitors land at Princess Juliana airport, which is on the Dutch side. The French side has its own networks, Orange Caraïbe, SFR Caraïbe and Digicel among them. Airalo and Holafly ride Digicel and Ubigi lists Digicel and Orange Caraïbe. Saily and Nomad do not name a network for their Saint Martin plans.
A Saint Martin plan is a French side plan. Holafly says so on its own page: its plan does not cover Sint Maarten. Saily and Ubigi name their plans French part, and Nomad names its plan Saint Martin (French). The brands that list both sides do it on regional plans: Airalo's Island Hopper, Saily's Caribbean Islands and Ubigi's Caribbean. Our own Saint Martin trip is sold for the French side too. If you are staying in Philipsburg, Simpson Bay or Maho, read our post on the best eSIM for Sint Maarten instead, at /blog/best-esim-for-sint-maarten.
Saint Martin is part of France and of the European Union, so EU roaming rules apply on the French side. A phone plan from an EU country roams there at home prices, within the usual fair use limit. Sint Maarten is not in the EU, so the same plan may charge you as soon as your phone picks up a Dutch side network, which can happen near the border, in Simpson Bay or at the airport. Pick a French network by hand if you want to stay on EU prices.
Ubigi, $19 for 10 GB. On its Best Caribbean regional plan, which also covers Guadeloupe, Martinique, Saint Barthélemy and French Guiana, on Digicel and Orange Caraïbe. Its own Saint Martin plans are small: 1 GB for 7 days at $4 and 3 GB for 15 days at $8.
Nomad, $23 for 10 GB. 20 GB for 30 days at $33 and 50 GB at $39, the most data for the money here, and 3 GB at $12. Nomad sells no unlimited for Saint Martin.
Airalo, $31 for 10 GB. Its Marnet plan on Digicel: 20 GB for $49, 5 GB for 30 days at $19. The app is needed.
Saily, $44.99 for 10 GB. 5 GB at $33.99 and 3 GB at $20.99. 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 cent under Ubigi's 10 GB, but it lasts 2 weeks, not 30 days. Our 30 days starts with 20 GB for $28.99, under Nomad's 20 GB at $33. For 10 GB that has to last a month, Ubigi is the better buy; for a few gigabytes, Ubigi's 3 GB at $8 costs far less than anything we sell; and for a heavy month, Nomad's 50 GB at $39 beats our month with a top-up. 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 Martin 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 Europe trip and our Caribbean trip do not cover the French side, so this is the Ringo Light to buy for it. It is sold for Saint Martin only, not for Sint Maarten, Anguilla or Saint Barthélemy.
The card to buy it is just below this article.
A long weekend. Airalo or Holafly unlimited, 3 days, $12.50. Ringo Light sells no 3 days; our 2 weeks is $6.49 more.
A week in Grand Case and Orient Bay. Ringo Light unlimited, 2 weeks, $18.99, less than any rival charges for 7 days of unlimited.
Two weeks, heavy use. Ringo Light unlimited, 2 weeks, $18.99, against $49 to $75 for two weeks at the rivals. Even with one top-up it is $37.98.
Light use, maps and messages. Ubigi 3 GB for 15 days at $8, or 10 GB for 30 days at $19 on its Best Caribbean plan.
A month or more. Ringo Light unlimited, 30 days, $28.99, starting with 20 GB and adding 10 GB once for $18.99. Nomad 50 GB for 30 days at $39 if you know you will use more than 20 GB.
You will spend days on both sides of the island. A regional plan that lists both, such as Ubigi's Caribbean or Saily's Caribbean Islands, or read our Sint Maarten post.
Your phone plan is from an EU country. Check your roaming first. The French side is in the EU, so you may already be covered at home prices.
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 Martin, and what your phone needs for it. Eight places most first trips to the French side include, from Marigot and Fort Louis to Grand Case, Orient Bay, the islet of Pinel and the monument on the border, with the one thing your data does for you at each. The whole French side is a short drive across, and the Dutch side is always close.
The Marigot waterfront, Marigot. The capital of the French side, with its market by the bay, the marina and the streets of shops behind it. Mornings are the liveliest, when the market stalls are full. Prices are in euros and US dollars are widely taken. Your bank app shows which rate you actually paid.
Fort Louis, Above Marigot. The ruins of an eighteenth century French fort on the hill over Marigot, reached by a short, steep walk from town. From the walls you see the bay, the lagoon and Anguilla across the channel. Go in the late afternoon for the light. Check the sunset time on your phone and start the climb half an hour before.
Grand Case, North coast. A small beach town known for its restaurants along one long street by the sea, and for the lolos, open-air grills serving ribs and fish. In the winter season, Tuesday evenings turn the street into a party. The best tables book up. Reserve on your phone a day ahead, and keep some cash for the lolos.
Orient Bay, East coast. The longest beach on the French side, pale sand with beach clubs and water sports, and the islet of Caye Verte just offshore. The trade winds make it a kitesurfing spot. Sargassum seaweed washes up on this coast in some seasons. Check a local sargassum report or beach webcam before you drive over.
Pinel Island, Off French Cul-de-Sac. A small, car-free islet a few minutes by boat from Cul-de-Sac, with two beach restaurants and calm water for snorkelling. The photo looks down over Cul-de-Sac bay, with Pinel on the right. The boats back stop in the late afternoon. Set an alarm for the last one.
Anse Marcel, North coast. A sheltered cove between green hills at the northern tip, with calm, shallow water and a marina. A coastal trail leads on from here toward Petites Cayes. Holafly warns that coverage can be weaker on the less developed northern beaches. Download an offline map before you walk the trail.
Baie Rouge, West end, Terres Basses. A long beach on the quiet west end of the island, with rocks to snorkel around at one end and Anguilla on the horizon. It is at its calmest on days without a north swell. This close to Anguilla your phone can pick up its networks. Pick a Saint Martin network by hand so your plan keeps working.
The border monument, On the road from Marigot to Philipsburg. A white obelisk marks the line agreed in 1648, when France and the Netherlands split the island. There is no checkpoint; you drive straight through. Past the monument you are in Sint Maarten, outside the EU. A French side plan may stop working and EU roaming may start to charge.
We priced Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Saint Martin 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 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 $49 for 15 days and $73 for 30 days at Airalo. For 3 days, Airalo and Holafly at $12.50. For a 10 GB bucket that lasts 30 days, Ubigi at $19.
Airalo and Holafly ride Digicel. Ubigi lists Digicel and Orange Caraïbe. Saily and Nomad do not name a network for their Saint Martin plans. All of these are French side networks.
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 for Saint Martin. Ringo Light has no speed cap: it starts with 10 or 20 GB and adds 10 GB once at 80%, charged.
Not as the brands sell them. Holafly states that its Saint Martin plan does not cover Sint Maarten, and Saily, Nomad and Ubigi name their plans for the French part. Ringo Light's Saint Martin trip is sold for the French side too. Regional plans such as Ubigi's Caribbean and Saily's Caribbean Islands list both sides. EU roaming from a European phone plan covers the French side only, since Sint Maarten is not in the EU.
