Saint Martin is a small Caribbean island shared between France and the Netherlands: the French north has Marigot and Grand Case, while the south, Sint Maarten, has Princess Juliana airport and Philipsburg. The border is barely noticeable on the road, so it is easy to visit both sides in a single day. The eSIM is installed at home, and on the island you only need to switch mobile data on.
This page is the quickest way to buy a travel eSIM for Saint Martin from 6 500 ₸. Pick a plan, pay online and install the digital SIM card at home before the flight — no passport and no queue at an airport kiosk.
The eSIM connects to local mobile networks, so you have data wherever they have coverage — Marigot and the rest of the country.
Compared with roaming in Saint Martin, an eSIM is usually much cheaper for mobile data: the price of the package is fixed and known in advance. Your home number stays active on the main SIM for calls and SMS.
If your phone does not support eSIM, you can buy a regular physical SIM card with data for Saint Martin at a Funsim point of sale: at Almaty and Shymkent airports, or at our offices in Almaty — 130/1 Abay St and 1 Pozharsky St. Handy if you remember about the internet right before departure.
The island is small, but a trip rarely stays on one beach: you start the morning on the French side, head to Maho for the planes at lunch and have dinner in Grand Case. Your phone may jump between the networks of the two sides on its own, especially near the border and around the lagoon. Before buying, open the plan page and make sure it works across the whole island, not just one part. If your route includes neighbouring islands, look at the regional plans too.
Keep your main SIM in the phone for calls and bank SMS codes, while mobile data goes through the eSIM. Most plans have no voice or SMS, so calling restaurants, villa owners and transfer drivers is easier through messengers.
| Criterion | Funsim eSIM | Roaming | Local SIM |
|---|---|---|---|
| When to set up | At home, before the flight | Usually on arrival | After landing, in a shop |
| Both sides of the island | Check the plan: it should cover both | Depends on your operator's terms | Usually tied to one side |
| Cost of data | Fixed package, see plans above | Usually much more expensive | Depends on the tariff |
| Home number | Stays for calls and banking | Stays | Usually a second SIM or a swap |
| Short trip | Convenient, nothing to find | Depends on your operator's terms | A shop visit eats holiday time |
Coverage in resort areas is usually good, but on hills, in coves and on boats the signal can be patchy. These are the places where you will want internet most.
The capital of the French side sits on the bay, with a harbour, Fort Louis and a waterfront market. It is handy to check the map, ferry timetables and opening hours here, and to read reviews before choosing a cafe. Mobile data also helps with banking apps when you pay by card.
A small village in the north known for restaurants along its main street. Tables for the evening are often booked in advance through messengers or maps, and you then drive back to your villa along dark roads. Working internet helps you find the right turn and message your hosts if you are running late.
A long beach on the east coast with cafes, sunbeds and water sports. Small boats run to Pinel from a nearby jetty, and the signal on the water can be weaker. Check the boat times and any booking in advance, and keep your phone in a waterproof case on the beach.
Quiet coves in the north of the French side. The roads go over hills and the signal can drop for a while. If you have a rental car, save the spot on an offline map. It is worth checking where to park beforehand and messaging a beach bar if its opening hours change.
The famous beach on the Dutch side where planes pass just above the water. Many visitors check flight schedules in the airport app or on airline sites so they arrive at the right moment. Internet also helps with taxis and with reaching your airline if a flight is delayed.
The capital of the Dutch side, along a long waterfront where cruise ships call. On cruise days the town is crowded and public Wi-Fi gets overloaded. Your own data is better for maps, translation and taxis, and on the Dutch side prices are often quoted in US dollars.
The lagoon area and western beaches on the Dutch side, with restaurants, nightlife and yachts. Many cafes take bookings through apps, and around the lagoon your phone may pick up the network of one side or the other. Check that mobile data runs through the right line.
Many visitors make a day trip to neighbouring islands. Ferries leave from Marigot and other ports, and coverage on each island differs. Check on the plan page whether it covers the island you want, and keep tickets and travel documents on your phone and offline.
You will not need special local services: the usual apps work the same on both sides of the island.
Shows roads, beaches, restaurants and opening hours on both sides. Download an offline map of the island so you do not depend on the signal on hills and in coves.
Usually how you reach hosts, car rental offices, drivers and restaurants. Calling over the internet is handy when your plan has no voice minutes.
Useful on the French side, where menus, signs and shops often use French. Download French for offline use and translate signs with the camera.
Help you find and confirm a place to stay and keep the address and host contacts at hand. Save confirmations on your phone in case the signal drops in a cove.
Flight updates, boarding passes and bank notifications are handy to have close. Keep your main SIM on for SMS codes and switch data on for the eSIM.
Check that your phone supports eSIM and is not locked to a carrier. You can find this in settings or from the manufacturer.
Find the plan for Saint Martin on the page, or a regional plan that includes the island, and make sure it covers both sides. Pay by card on the site; no passport is needed.
Install the eSIM at home by QR code, the quick install button or manually while you still have Wi-Fi. That way data is ready as soon as you land.
After arrival, choose the eSIM as the line for mobile data and switch on data roaming for that line.
Keep your main SIM for calls and bank SMS, but turn off data on it so you do not pay roaming charges.
If the package runs out, buy extra data on the site. Hotspot can be used where the plan allows it; see the terms on the plan page.
If your phone keeps switching between the networks of the two sides near the border or lagoon, turn off automatic network selection for the eSIM line and pick an operator manually in settings.
