The short answer
Six travel eSIMs sell data for Saint Martin, the French side of the island, and get most of the traffic for this search. I 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 I 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.
Unlimited data at full speed for 2 weeks at $18.99 or 30 days at $35.99, nothing renews. Airalo asks $49 for 15 days and $73 for the month.
3 days of unlimited at $12.50 on Digicel, 3 GB a day at full speed, then 1 Mbps. Holafly asks $13.50.
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.
50 GB for 30 days at $39 and 20 GB at $33 on its Saint Martin plan. Nomad sells no unlimited here.
Prices read on 31 October 2026: Airalo, Holafly, Saily, Nomad, Ubigi on their own sites or listings, Ringo Light from its catalogue. All in US dollars unless stated. Treat every number as a snapshot.

The prices, charted
US dollars, Holafly read 31 October 2026, the others 28 September 2026. The rivals sell 15 days, Ringo Light 2 weeks. Ubigi's bar is its Caribbean regional plan: 30 GB at full speed, then 2 Mbps. Saily and Nomad sell no two weeks of unlimited here.
The 30-day plan at each brand. Ringo Light is unlimited data at full speed. Saily's month is its Global plan, 30 GB at full speed, then 1 Mbps. Ubigi's is its Best Caribbean regional plan, 60 GB, then 2 Mbps. Nomad sells no unlimited.
Holafly sells no buckets. Ringo Light sells no bucket either: its 2 weeks is unlimited and lasts 2 weeks, not 30 days. Ubigi's 10 GB is its Best Caribbean regional plan.

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.
If you want unlimited for two weeks or a month: Ringo Light
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, I read Airalo at $49 and Holafly at $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, 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 $35.99 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 is unlimited data at full speed for the whole 7 days, 2 weeks or 30 days.
For a short trip, Ringo Light sells no 3-day plan. Airalo sells 3 days of unlimited at $12.50 and Holafly at $13.50, so Ringo Light's 7 days at $5.99 costs less than either brand's 3 days. For a week, Ringo Light's 7 days at $5.99 costs less than any rival's 7 days, and I would buy it: Airalo asks $27.50, Holafly $27.90, and Ubigi $27 for 20 GB at full speed on its Best Caribbean plan.
One island, two sides, two sets of networks
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. Ringo's Saint Martin trip is sold for the French side too. If you are staying in Philipsburg, Simpson Bay or Maho, I would read the 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.
If you want a data bucket: Ubigi or Nomad
- 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 refused the fetch, so I did not re-read it.
- ✓Ringo Light, no buckets. Ringo Light's 2 weeks is unlimited for $18.99, one cent under Ubigi's 10 GB, but it lasts 2 weeks, not 30 days. Its 30 days is unlimited for $35.99, $2.99 more than 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 Ringo sells. I would rather you read that here than at checkout.
What Ringo Light is
I write for Ringo, so weigh that. Ringo Light is the 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 three trips, all unlimited data at full speed with no speed cap: 7 days at $5.99, 2 weeks at $18.99 and 30 days at $35.99. Nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
Ringo's Europe trip and Caribbean trip do not cover the French side, so this is the Ringo Light I would buy for it. It is sold for Saint Martin only, not for Sint Maarten, Anguilla or Saint Barthélemy.
The card to buy it is further up this page, just after the side-by-side table.
Pick by trip
Airalo unlimited, 3 days, $12.50, or Holafly at $13.50. Ringo Light sells no 3 days; its 2 weeks is $6.49 more.
Ringo Light unlimited, 7 days, $5.99, less than any rival charges for 7 days of unlimited.
Ringo Light unlimited, 2 weeks, $18.99, against $49 to $75 for two weeks at the rivals.
Ubigi 3 GB for 15 days at $8, or 10 GB for 30 days at $19 on its Best Caribbean plan.
Ringo Light unlimited, 30 days, $35.99.
A regional plan that lists both, such as Ubigi's Caribbean or Saily's Caribbean Islands, or read the Sint Maarten post.
Check your roaming first. The French side is in the EU, so you may already be covered at home prices.
None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
