609 of these 933 plans were checked against the seller's own shop on 17 October 2026. The rest come from the seller's own feed or plan pages and are not yet independently checked.
The Watchdog Pick is chosen automatically: the lowest real price per GB of the 933 plans in this view. Bulk data pools above 50 GB cannot win it, because their per GB rate only exists if you use data no traveller uses. Providers cannot pay for it, and a commission never changes the ranking. Prices are shown in USD and can change at checkout.
Price per GB counts only data you can use inside the validity, at most 3 GB a day, so a big pool on a short validity cannot buy the top spot. Every provider's best two plans come first, then the rest. A plan marked Unverified price undercuts every other provider here by more than half and waits at the end until we have checked it on the seller's site. How we rank
Unlimited rows show the daily amount at full speed. Some rows also show the speed after that amount. A row with no speed does not mean the plan stays fast, so check the plan on the seller's site.
Some links here earn us a commission. It never changes the order. How we make money The row marked Sponsored is a paid placement shown above the ranking, not part of it. Advertise here.

Cheapest eSIM for St Martin: the numbers
As of 17 October 2026, 06:01 GMT, the cheapest eSIM for St Martin is Yatelo with 10 GB for 30 Days at $3.99. That is $0.40 per GB, the best rate of the 933 plans we compare from 46 providers. 548 plans include 5G. 463 support top ups. That timestamp is the exact moment of our latest price check, and the table above always shows the live order.
Which is the best eSIM for St Martin?
There is no single best eSIM for St Martin, because the right plan depends on how long you stay and how much data you use. What we can do is rank the 933 plans on the numbers, as they stand on 17 October 2026:
- Best value overall Yatelo, 10 GB for 30 Days at $3.99. That is $0.40 per GB, the lowest real rate of every St Martin plan we track.
- Best for a short trip AlpineSIM, 1 GB for 7 Days at $0.81. The cheapest ticket that still gives you at least 1 GB for a week or less.
- Highest daily cap on an unlimited plan SimSmash, 1 Day at $4.99, full speed up to 10 GB a day. Set that daily cap against the fixed plan above before you pay for the word unlimited.
None of these picks is chosen by a person. Each one is the first row of a sort on live prices, so it changes whenever a provider moves a price, and Yatelo did not pay to be named here.
Which mobile networks does St Martin have?
The island is split between France and the Netherlands and networks from both sides overlap, so phones often latch onto whichever signal is stronger near the border.
- Orange Caraibe: Orange serves the French side and its SIMs roam on the Dutch side through Telcell at no surcharge.
- Dauphin Telecom: Dauphin Telecom is the local operator of the French Caribbean islands and covers Saint Martin with prepaid offers.
- Digicel: Digicel covers the island, but its local SIMs charge roaming fees when you cross to the Dutch side.
- UTS Caraibe: UTS Caraibe, linked to the Chippie brand, holds a licence for the French side that runs from May 2025.
The eSIM plans we compare on this page connect to:
The list above is St Martin's operator market. The badges are the networks our tracked plans actually roam onto, which can be a subset of it, and the same network is sometimes sold to roaming partners under a different brand name. So a guide praising an operator you do not see badged here is describing a local SIM, not the travel eSIMs compared above.
Is 5G available in St Martin?
The Arcep licences that took effect in May 2025 cover the 900 MHz, 1800 MHz and 2.1 GHz bands, which serve 2G to 4G. No 3.5 GHz 5G band has been assigned on the island.
How much data do you need in St Martin?
Light use is about 500 MB a day. That covers maps, messages, and some browsing. Normal use with photos, social apps, and short videos runs 1 to 1.5 GB a day. Streaming and hotspot use can eat 2 to 3 GB a day. Here is what each size costs in St Martin right now:
Are unlimited eSIMs for St Martin really unlimited?
Not always. 362 of the 933 plans above are sold as unlimited, and most of them carry a daily fair use cap. A further 9 plans are unlimited in a different way: one capped speed for the whole plan, shown next to the word Unlimited in the table. For St Martin the caps we can see published are 0.5 to 10 GB a day: past that the speed drops, often to 1 Mbps or less, until the clock resets. That is fine for messages and maps, slow for video. At $0.40 per GB from Yatelo, a fixed plan often works out cheaper than unlimited unless you genuinely burn several GB a day. That is why we rank by price per GB and not by the word on the label.
Here is what each seller on this page actually allows per day before it slows you down. No seller publishes this next to its rivals, which is exactly why it is worth showing.
Every seller that publishes a daily allowance is listed on our daily data caps page, with the cheapest plan at each one. The gap between the top and bottom of that table is the whole point. Two plans both sold as unlimited can differ several times over in what you actually get at full speed, and the cheaper one is not always the smaller allowance.
eSIM or a local SIM card at the airport in St Martin?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter for a tourist SIM card. Data for St Martin starts at $0.54 on this page, which is hard for airport kiosks to beat. A local SIM still makes sense if you need a local phone number or plan to stay for months. For a normal trip, the eSIM wins on price and effort.
Setting up your St Martin eSIM
Pick the plan, not the brandThe cheapest rate in St Martin today is $0.40 per GB from Yatelo, against a median of $1.50. The QR code arrives by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Installation needs a connection, and the one thing you will not have when you land in St Martin is a working connection.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to attach to Digicel, Orange, Orange Caraibe, Telcell N.V.. Expect 5G where the network reaches, 4G everywhere else.
Know what happens when it runs out463 of the 933 plans here can be topped up, so running out is not the end of the trip. If you would rather over buy than top up, the cheapest plan with at least 5 GB is Yatelo at $2.31.
Good to know before you land in St Martin
The French side is an EU outermost region, so EU roam like at home applies there. The Dutch side, Sint Maarten, is outside the EU zone and can trigger extra roaming charges.
Most visitors land at Princess Juliana airport on the Dutch side, where only Flow Chippie SIMs are sold. Grand Case Esperance airport on the French side sells no SIMs at all.
Watch which network your phone picks up. A French side SIM from Orange or Dauphin roams free on the Dutch half through Telcell, but a Digicel local SIM does not, and an EU plan can bill Dutch side use at non EU rates.
St Martin Travel eSIM FAQ
Everything you need to know about using an eSIM in St Martin
What is the cheapest eSIM for St Martin?
Right now the cheapest option ranked by price per GB is Yatelo with 10 GB for 30 Days at $3.99. That works out to $0.40 per GB. Prices change often, so the table above is re-sorted at every price check.
Which is the best eSIM for St Martin?
It depends on the trip, so we rank rather than pick a favourite. On today's prices the best value for St Martin is Yatelo at $0.40 per GB, the lowest real rate of the 933 plans we compare. For heavy daily use there are 362 unlimited plans, most with a daily fair use cap, and they only win if you genuinely burn several GB a day. Every pick on this page is the first row of a sort on live prices. No provider can pay to be named best.
Is eSIM available in St Martin?
Yes. We track 933 prepaid travel eSIM plans from 46 providers that work in St Martin, roaming onto Digicel, Orange, Orange Caraibe, Telcell N.V.. You need a phone that supports eSIM and is not locked to a carrier; most iPhones from the XS onward and most flagship Android phones from 2019 on qualify.
Which networks will my eSIM connect to in St Martin?
The plans we compare connect to Digicel, Orange, Orange Caraibe, Telcell N.V.. The exact network depends on the plan you pick. Check the plan details before you buy if one network matters to you.
Do St Martin eSIMs support 5G?
548 of the 933 plans we track for St Martin include 5G where the local network offers it. The rest run on 4G, which is still fine for maps, calls over apps, and video.
Can I buy a St Martin eSIM online before I travel?
Yes, and you should. Every plan on this page is sold online and delivered by email as a QR code within minutes. Install it on wifi at home, leave the line switched off, and turn on data roaming for it when you land in St Martin. The validity clock on most plans only starts when the eSIM first connects.
Can I top up my St Martin eSIM if I run out?
Yes. 463 of the 933 plans here support top ups, so you can add data without buying a new eSIM. The rest need a fresh plan once the data ends.
Is an eSIM cheaper than a local SIM card in St Martin?
For a trip of days or weeks, usually yes. Data for St Martin starts at $0.54 for 200 MB on this page, with no queue, no shop and no passport handed over at a counter. A local SIM card can still win if you stay for months or need a local phone number.
Will I still receive bank SMS and OTP codes?
Yes, if you keep your home SIM active. Travel eSIMs are data only. Your phone can hold both at once, so leave your normal SIM on for SMS and use the eSIM for data. Turn off roaming data on the home SIM to avoid charges.
Do these eSIMs include a phone number or calls?
The plans we compare are data only, so there is no local number. Calls work fine over WhatsApp, FaceTime, or any app that uses data. If you need a real local number, a local SIM is the better tool.
Does a St Martin eSIM work on iPhone and Android?
Yes, on any carrier unlocked phone with eSIM support: iPhone XS or newer, Google Pixel 3 or newer, Samsung Galaxy S20 or newer and most recent flagships. The plans are identical on both; only the install steps differ, and both take about a minute on wifi.
How many GB do I need for a week in St Martin?
Around 3 to 5 GB covers a week of maps, messaging, and normal browsing. Heavy video or hotspot use needs 1 to 2 GB per day. Today the cheapest plan with at least 5 GB is Yatelo at $2.31.
Which St Martin eSIM gives the most data per day?
Of the plans sold as unlimited here, SimSmash allows the most at full speed, 10 GB a day from $4.99. The smallest allowance on this page is 500 MB a day, from 2 sellers. Every one of them is advertised as unlimited, and past the daily allowance the speed drops, often to 1 Mbps or less, until the next day. Check the allowance, not the word.
