St. Martin eSIM: what to know before you travel
Which St. Martin eSIM plan should you choose?
Budget around 1 GB per week if you stick to maps, messaging and bookings. For a typical one- to two-week trip with social media, photos uploaded each evening and the odd video call, 5 to 10 GB is the right size. Beyond that — remote work, streaming, sharing your connection with the family — go for 20 GB or an unlimited plan. Picked the wrong one? It doesn't matter: the eSIM is rechargeable, so you add data mid-trip without reinstalling anything.
How much does a St. Martin eSIM cost?
Plans for St. Martin start at $1.49, and the price table above lists every option with its data, validity and exact price — no surprise charges when you land. The comparison that matters isn't with a local SIM card, it's with your operator's roaming: a few dollars for the whole trip instead of a bill calculated per megabyte. What you see is what you pay, once, and the eSIM never auto-renews.
Do you need a QR code to install your St. Martin eSIM?
No — and this is exactly the part travellers dread for no reason. Your confirmation email contains a Quick Install link: open it on the phone you're taking with you, tap once, and iOS (17.4 and later) opens the eSIM installer with every setting already filled in. No second screen, no camera, no typing an SM-DP+ address. The QR code and manual setup are still in the same email if you prefer the classic method or you're on Android.
Can you top up your eSIM once you are there?
Yes, and that is the real difference from an airport SIM card. If your data runs out halfway through your trip, you open the top-up page with your order number, pick a new package, and the data lands on the eSIM you already installed within seconds. Nothing to reinstall, no shop to find, no ID to show. Your usual number also stays active on your physical SIM throughout the trip: calls, texts and banking verification codes keep arriving as normal.
St. Martin: detailed coverage
St Martin fills a small island of beaches and green hills, and almost every visitor crosses between its two sides during a stay. Marigot's market and the sands at Grand Case, Orient Bay and Friar's Bay sit on one side; Philipsburg, the cruise berths and the aircraft coming in low over Maho Beach are on the other. Distances are tiny, the roads are busy, and the drive between the two is short enough to do twice in a day.
A St Martin eSIM gives you a fixed price agreed before you travel, rather than a roaming total worked out afterwards.
How much data. A week of beach-hopping, restaurant bookings and photographs generally fits in 3 GB. A fortnight, or two phones sharing one connection, is nearer 5 to 10 GB. Anyone posting video from the water each day should take more.
- Marigot, Grand Case and the main coastal roads are well covered, as are the developed bays.
- The island is shared between two sides, so phones near the boundary can switch networks without warning, and the hill roads between them have gaps.
- Boat trips to Anguilla, Pinel or Tintamarre lose signal offshore, so download your booking before you board.
Weather runs the calendar. The island has a distinct quiet season when some restaurants and boat operators close, and checking what is running that week is worth doing before you set out rather than on arrival.
Data only, so nothing changes for calls. Your own number stays active for SMS and the verification codes a bank sends during a card payment abroad.
Choose a plan below to match your stay, from a few beach days to a fortnight. It is delivered at once and starts only when you arrive.

FAQ
St. Martin eSIM — frequently asked questions
How do I install my St. Martin eSIM?
Your St. Martin eSIM arrives by email right after payment, as a QR code. Scan it from your phone settings (Add eSIM), turn on data roaming for the new line, and you’re connected. No QR handy? Use the quick-install link included in the same email.
Follow the visual walkthrough: iPhone guide · Samsung / Android guide.
When should I install it before my trip?
Ideally at home, before you fly — the plan only starts on arrival, once data roaming is on. You have up to 180 days after purchase to activate it, so buying early costs you nothing.
What coverage does the St. Martin eSIM offer?
Your eSIM connects automatically to the best local partner networks available. The full coverage details are listed in the Description tab above.
How long do the St. Martin plans last?
The plans on this page are valid for: 7 DAYS, 30 DAYS, 15 DAYS. The clock starts at activation on arrival, not at checkout — with a 180-day window to activate after purchase.
Can I add more data later?
Yes — this eSIM is rechargeable. Head to the recharge page with your order number, choose a package, and the data lands on your existing eSIM in seconds. No new installation needed.
How can I see how much data is left?
Enter your order number on the recharge & usage page to view your remaining balance and every plan linked to your eSIM.
Does hotspot / tethering work?
It does — turn your phone into a Wi-Fi hotspot and share your data with a laptop, tablet or travel buddy.
What if I run out of data?
Your eSIM simply goes offline — never a surprise bill. Recharge it in a few seconds from the recharge page and you’re back online on the same eSIM.
Will WhatsApp and my usual number keep working?
Absolutely. Your home SIM stays in place for calls, SMS and your WhatsApp account, while the eSIM quietly carries your internet. Remember to switch off data on your home line to dodge roaming fees.
How does unlimited data work here?
Unlimited plans are built for normal travel use — maps, socials, streaming in moderation. Very heavy usage (large downloads, constant background streaming) may be slowed under the fair-use policy. Read the full policy.
