Saint Barthélemy, or St Barths, is a small French island in the Caribbean, where people usually go for a beach holiday, a yacht trip or a quiet stay in a villa. The island is small but hilly, and a trip almost always involves transfers, taxis, restaurant bookings and messages to hosts. It is better to set up the eSIM at home in advance, so that after arrival you only need to switch data on.
This page is the quickest way to buy a travel eSIM for Saint Barthelemy 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 — Gustavia and the rest of the country.
Compared with roaming in Saint Barthelemy, 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 Barthelemy 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.
Saint Barthélemy is an overseas territory of France rather than a separate country on the usual list of destinations. So plans for it may be listed separately or be part of regional plans: Caribbean or French ones. Before buying, open the plan page above and make sure the island is in the coverage list.
Your main SIM stays in the phone for calls and bank SMS, while mobile data goes through the eSIM. Most plans have no voice calls or SMS, so messengers are the easiest way to agree things with villa hosts, drivers, boat captains and restaurants. On a small island this is especially noticeable: many services are booked in advance and confirmed by message rather than in person.

The island is small, but signal can differ from bay to bay because of the hills, and at sea it weakens as you move away from the shore. These are the places where you will use the internet most.
The capital and main port of the island, with a waterfront, shops and restaurants. Yachts and ferries come in here, so you need internet for checking schedules, booking dinner and contacting the crew or driver. In the evening the harbour is busy and venue Wi-Fi can be overloaded, while mobile data is more reliable.
The area around the airport with a beach, shops and restaurants. The planes here are small and the runway is short, so weather and flight schedules matter, and it is convenient to check them online. After landing you need internet to call a transfer, write to the villa host and find your way on narrow roads with steep climbs.
A lagoon in the north-east with shallow water, hotels and beaches that are calmer than the open shores. People like kitesurfing and family holidays here. Internet helps to book lessons, check the wind and arrange rentals, and in small coves signal can differ slightly from the centre of the island.
Beaches on the south side of the island next to the salt ponds, where many people come for the whole day with food and an umbrella. The area is open, the roads are narrow and parking is limited. Internet is needed for navigation, checking the weather and contacting your driver if you came by taxi and want them to come back for you.
A secluded bay in the north-west reached by boat or on foot along a trail. There is no usual infrastructure here, and signal on the trail and in the bay can be weak. Download an offline map, take water and agree on a return time in advance, especially if you go with a boat company.
Two popular shores: Flamands in the north with a wide sandy beach, and Shell Beach near Gustavia, known for its shells and a bar. These are places where people spend a lot of time during the day. Mobile data is needed for booking tables, ordering an evening taxi and chatting with friends when you are spread across different beaches.
Quiet villages in the north-west and north of the island with houses, fishing boats and small restaurants. People come for the atmosphere and lunch, usually for a few hours. Internet helps to find an open cafe and call a car, and the road runs over hills where signal can briefly drop.
Many people reach the island not by plane but by sea from neighbouring Saint-Martin. During the crossing, signal depends on the weather and distance from the shore, and the crossing itself depends a lot on the swell. Buy tickets and save the schedule before you fly, and use internet on board only as a backup.
Most familiar services work as in Europe, but a few apps are especially useful on the island.
Needed on narrow, hilly roads and for finding beaches, shops and restaurants. Download an offline map of the island in advance so you do not depend on signal in remote bays.
The main way to agree things with villa hosts, drivers, restaurants and boat companies. If your plan has no voice calls, it is the easiest way to call or send your location.
The main platforms for booking hotels and villas. Save confirmations, the address and check-in instructions on your phone in advance so they are available without internet.
The main language of the island is French, although in tourist places English is understood more often than in other French regions. Download French for offline use to translate menus and signs with the camera.
Forecasts of wind and waves, handy for boat trips, kitesurfing and the hurricane season. Check the weather in the morning before going out to sea and do not rely on signal far from the shore.
Check that your phone supports eSIM and is not locked to a carrier. You can find this in the settings or on the manufacturer's website.
Open the plan page for Saint Barthélemy or a suitable regional plan and make sure the island is in the coverage. 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 you will not need to look for internet at the airport or the port.
After landing or arriving by ferry, choose the eSIM as your mobile data line and switch data roaming on for that line.
Keep your main SIM on for calls and bank SMS, but turn off mobile data on it so traffic does not go through roaming.
If you travel via Saint-Martin, switch the eSIM on only after you reach the island, and save tickets and your accommodation address on the phone in advance.
