The short answer
Six travel eSIMs get most of the traffic for this search. Five of them sell something that works on Sint Maarten, the Dutch side of the island, some with a plan for Sint Maarten and some with a Caribbean or world plan; Holafly sells only the French side. I priced all five, with the date each figure was read, for a long weekend, two weeks on the beaches and a month. I read the fine print on unlimited and checked which plans also work across the border in French Saint Martin. Here is where each one wins.
Unlimited data at full speed for 2 weeks at $50.99 or 30 days at $95.99, nothing renews. Ubigi asks $75 for 15 days with 30 GB at full speed, and $99 for a month of 60 GB.
Its Caribbean plan lists Sint Maarten and French Saint Martin: 7 days with 20 GB at full speed for $44, then 2 Mbps, and 10 GB for 30 days at $34.
Its Island Hopper plan covers 26 Caribbean countries, both sides of the island included: 3 days at $19.50, 3 GB a day at full speed. Its own Sint Maarten plan sells buckets only, on Telcell.
10 GB for 30 days at $28 and 20 GB at $39 on its plan for Sint Maarten and Curacao, on FLOW. No unlimited plan.

What to do in Sint Maarten, and what your phone needs for it
Eight places most first trips to the Dutch side include, from Maho Beach at the end of the runway to Philipsburg and the border with French Saint Martin, with the one thing your data does for you at each. Signal is good almost everywhere; the tips are mostly about flights, cruise days, bridges and the border.
If you want unlimited for two weeks or a month: Ringo Light
Most trips to Sint Maarten are a week or two in Simpson Bay, Maho or Philipsburg, and data is what you use for maps, WhatsApp with taxis, boats and restaurants, and streaming in the evening. For about two weeks of unlimited, Ubigi asks $75 for 30 GB at full speed on its Caribbean plan, and Airalo $96 on its Discover global plan or $99 on Island Hopper. For a month, $99 at Ubigi and $159 at Airalo. Saily and Nomad sell no unlimited here. Ringo Light charges $50.99 for 2 weeks and $95.99 for 30 days, nothing renews, and for these trips I count it as the cheapest unlimited.
Read what unlimited means before you pick. Airalo gives 3 GB a day at full speed, then 1 Mbps. Ubigi gives 20 GB for 7 days, 30 GB for 15 days or 60 GB for the month, then 2 Mbps. Ringo Light is unlimited data at full speed for the whole 2 weeks or 30 days.
For a short trip, Ringo Light sells no 3-day or 7-day plan. Airalo sells 3 days of unlimited at $19.50, and Ubigi a week with 20 GB at full speed at $44, $6.99 less than the 2 weeks of Ringo Light. For a week I would buy the Ubigi plan.
One island, two countries: will your plan work on the French side?
The island is split between Sint Maarten, the Dutch south, and Saint Martin, the French north. The border is open, and most visitors cross it for lunch in Grand Case or the market in Marigot without noticing. Your phone notices: the two sides have their own networks, and travel eSIMs treat them as two countries.
Here is what each brand states. Airalo's Sint Maarten plan lists Sint Maarten only; its Island Hopper lists both. Saily's Sint Maarten plan lists Sint Maarten only; its Caribbean Islands plan lists both. Nomad's plans list Sint Maarten but not Saint Martin. Ubigi's Caribbean and world plans list both. Holafly's Saint Martin plan says it does not include Sint Maarten. Ringo Light's Sint Maarten trip works across Sint Maarten only, and its Caribbean trip covers Sint Maarten but not Saint Martin. I would not trust a one-side plan across the border: expect data to drop when your phone can only find the other side's networks.
If you are staying on the French side, read /blog/best-esim-for-saint-martin instead. If you will split your days between both, Ubigi's Caribbean plan or Airalo's Island Hopper is the simpler buy.
Networks, money and getting around
Sint Maarten is small and hilly, and the networks cover Philipsburg, Simpson Bay, Maho and the main beaches well. Airalo's plans for the island ride Telcell, Ubigi lists Telcell and UTS, and Nomad FLOW; Saily does not name its network.
US dollars are taken almost everywhere, and most restaurants and hotels take cards. Taxis are the usual way around, booked by phone or at the stands; agree the fare before you get in. I would do the same with the fare each time.
If you want a data bucket: Nomad or Ubigi
- Nomad, $28 for 10 GB. On its plan for Sint Maarten and Curacao, on FLOW, and the cheapest 20 GB for 30 days at $39 that does not renew. It does not list the French side.
- Ubigi, $34 for 10 GB. On its Caribbean plan, which also works on the French side. Its World plan sells 20 GB a month for $44, but it renews every month until you stop it.
- Saily, $46.99 for 10 GB. On its Caribbean Islands plan; its own Sint Maarten plan stops at 1 GB for 7 days at $7.99. Its listing is from May; saily.com would not load when I tried.
- Airalo, $48 for 10 GB. On its Island Hopper plan, or $49 on its Sint Maarten plan, which starts at 1 GB for 3 days at $8.
- ✓Ringo Light, no buckets. The 2 weeks is unlimited for $50.99 and the 30 days unlimited for $95.99. For a fixed amount of data, Nomad, Ubigi, Saily and Airalo are all cheaper in Sint Maarten. I would buy Ringo Light for unlimited, not for a bucket, and I would rather you read that here than at checkout.
What Ringo Light is
Ringo Light is the data eSIM from Ringo, the company I write for, sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Sint Maarten it sells two trips, both unlimited data at full speed with no speed cap: 2 weeks at $50.99 and 30 days at $95.99. Nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app. It works in Sint Maarten only, not on the French side.
The Caribbean trip from Ringo Light is cheaper for Sint Maarten than its Sint Maarten trip, and I checked both prices: $47.99 for 2 weeks against $50.99, and $90.99 for 30 days against $95.99. It covers Sint Maarten and six more countries, including Puerto Rico and the Dominican Republic, but not French Saint Martin. If Sint Maarten is on its list for you, I would buy that one; it is compared in /blog/best-esim-for-caribbean.
The card to buy it is further up this page, just after the side-by-side table.
Pick by trip
Airalo Island Hopper unlimited, 3 days, $19.50, and it works on both sides of the island. Ringo Light sells no 3 days.
Ubigi Caribbean, 7 days with 20 GB at full speed, $44, less than the 2 weeks of Ringo Light, and it works on the French side too.
Ringo Light unlimited, 2 weeks, $50.99, or its Caribbean trip at $47.99, less than any rival charges for two weeks.
Nomad, 10 GB for 30 days at $28, or Ubigi at $34.
Ringo Light unlimited, 30 days, $95.99, or its unlimited Caribbean trip at $90.99. I would take the Caribbean trip if you stay on the Dutch side.
None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
