サンマルタン eSIM

eSIM for San Martín: internet without roaming

The island of San Martín is divided into two: the French side (Saint-Martin, with its capital in Marigot) and the Dutch side (Sint Maarten, with its capital in Philipsburg). With an eSIM for San Martín, you have mobile data as soon as you land, without having to look for stores or change your physical SIM card. The eSIM connects to the local networks operating on the island, such as Orange Caraïbe and Dauphin Telecom on the French side, or Flow and TelCell (Chippie) on the Dutch side, so you can browse with good coverage throughout the island.

Roaming in San Martín: why an eSIM is convenient for you

Although the French side depends on France, San Martín is not part of the European Union's roaming zone. That means using your home plan by activating roaming in San Martín can cost you between 10 and 15 € per day, with surcharges for calls and per megabyte. A data eSIM avoids that surprise bill: you pay a fixed plan before traveling and control your spending from the first minute.

How much does an eSIM for San Martín cost?

Plans start from 3.95 € and you choose based on the days and usage. For a short beach trip with light browsing, 1 or 2 GB is usually enough; if you plan to share photos, use maps daily, and make video calls, calculate about 1 GB for every two or three days. This price of an eSIM for San Martín is much lower than traditional roaming, and you know in advance what you will pay.

eSIM or physical SIM card in San Martín

Buying a physical SIM card in San Martín forces you to find a point of sale, present an ID, and wait for activation, and often they sell you separate ones for the French side and the Dutch side. The eSIM is completely digital: it is installed via a QR code, does not occupy your phone's physical slot, and you can keep your usual number active for WhatsApp and SMS while using the local plan's data.

Does the eSIM work in Marigot, Philipsburg, and Grand Case?

Yes. Coverage covers the main hubs on both sides: Marigot and Grand Case in the French area, and Philipsburg, Simpson Bay, and the Princess Juliana airport area in the Dutch area. The eSIM relies on the antennas of real operators on the island, so you will have internet in San Martín both on the beaches of Orient Bay and in the shopping center on Front Street, or when crossing from one side to the other without changing your card.

How is the San Martín eSIM activated?

After purchase, you receive a QR code and instructions by email. You scan it from your phone's settings, ideally before leaving home with Wi-Fi, and the plan is ready to activate upon arrival.
