Prepaid data plans for French Saint Martin
esimbloom lists 21 prepaid eSIM plans for Saint Martin (French) from $1.37 (the smallest is 1GB for 7 days). Every plan is data-only — mobile internet for maps, messaging and bookings, but no local phone number or SMS — and prepaid: pay once, no contract, no roaming charges.
Plans connect to the local mobile network using the local mobile network at whatever speed it and your device support. You can browse, navigate, message over the internet, and share your connection with other devices via hotspot. Voice calls and SMS are not included, though you can use internet-based calling apps over your data allowance.
How to set up your eSIM for Saint Martin
Check that your phone supports eSIM technology before you buy. Most recent iPhones, Samsung Galaxy models, and Google Pixels are compatible. Once you complete your purchase, the QR code arrives by email. Install the eSIM profile while you still have WiFi, either at home or at the airport, but leave it turned off until you land.
When you arrive in French Saint Martin, enable the eSIM data line in your phone settings and turn on data roaming for that line only. The profile connects automatically. Your home SIM stays in the phone, so you can still receive verification codes or calls to your usual number while using the eSIM for data.
Staying connected around French Saint Martin
Marigot, Grand Case, and the main coastal towns have reliable mobile coverage. You will have connectivity along the coast road between Orient Bay and Friar's Bay, and most beaches on the French side are well covered. Navigation apps work throughout the developed areas, and rideshare or restaurant bookings will load without issue. Coverage thins in the interior hills near Pic Paradis, though the island is small enough that most travellers stay near the shore.
