esimbloom lists 22 prepaid eSIM plans for Saint Martin 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.
esimbloom does not currently offer a single-country plan for Saint Martin. Instead, travellers are covered by regional Caribbean plans and global multi-country plans. Both give you prepaid mobile data across the island without a physical SIM card or roaming fees.
Each plan is data-only. You will have mobile internet for maps, messaging apps, and travel bookings, but no local phone number for voice calls or SMS. The plans run on the local mobile network at whatever speed it and your device support.
How to set up your eSIM for Saint Martin
Check that your phone supports eSIM technology before you buy. Most iPhones from XS onward and recent Samsung, Google Pixel, and other flagship Android models are compatible. Choose a regional or global plan that covers Saint Martin, complete payment, and you will receive a QR code by email within minutes.
Install the eSIM before you travel by scanning the QR code in your phone's settings. Keep your home SIM active until you leave, then switch to the eSIM data plan on arrival. The eSIM activates when it first connects to a mobile network in a covered destination, so you can install it days in advance without starting the validity clock.
Staying connected across Saint Martin
Saint Martin is a small island, and mobile coverage reaches the main towns of Marigot and Grand Case on the French side, as well as the beaches along Baie Orientale and the coastal roads. The Dutch side, Sint Maarten, shares the same island and your regional or global plan covers both territories without additional cost. Connectivity is generally reliable in populated areas and around Princess Juliana Airport.
Travellers typically use data for navigation between beaches, booking restaurant tables, and staying in touch via WhatsApp or similar apps. Coverage can be lighter in the interior hills and along remote coastal stretches, but most visitors stay close to the shoreline where signal is consistent. If you are island-hopping to Anguilla or Saint Barthélemy, confirm that your chosen plan covers those destinations as well.

Do I need an eSIM for Saint Martin?

Does esimbloom offer a dedicated eSIM plan for Saint Martin?
No single-country plan is available for Saint Martin at present. The island is covered by esimbloom's regional Caribbean plans and global plans, both of which include Saint Martin in their coverage footprint.
Will my eSIM work on both the French and Dutch sides of the island?
Yes. Saint Martin and Sint Maarten share the same island, and regional and global plans cover both territories. You do not need separate plans or manual switching when you cross the border.
Can I make phone calls or send SMS with an esimbloom eSIM in Saint Martin?
No. esimbloom plans are data-only and do not include a local phone number. You can use internet-based services like WhatsApp, FaceTime, or Skype for calls and messages over your mobile data connection.
