600 of these 938 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 938 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 Barthelemy: the numbers
As of 17 October 2026, 06:01 GMT, the cheapest eSIM for St Barthelemy is Yatelo with 10 GB for 30 Days at $3.99. That is $0.40 per GB, the best rate of the 938 plans we compare from 46 providers. 548 plans include 5G. 458 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 Barthelemy?
There is no single best eSIM for St Barthelemy, because the right plan depends on how long you stay and how much data you use. What we can do is rank the 938 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 Barthelemy 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 $5.19, 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 Barthelemy have?
4G covers the main areas of this small island, with brief signal drops reported in narrow valleys and on steep hillside trails.
- Orange Caraibe: Orange serves Saint Barthelemy with a shop at the Neptune centre in Saint Jean and tourist SIMs for about 15 EUR.
- Dauphin Telecom: Dauphin Telecom is the local Caribbean operator, with a shop on Rue Oscar II in Gustavia and SIMs from about 14.90 EUR.
- Digicel: Digicel covers the island and sells the cheapest tourist SIM at about 10 EUR.
- Free Caraibe: Free Caraibe won spectrum on the island in the Arcep licensing round and its licence runs from May 2025.
The eSIM plans we compare on this page connect to:
The list above is St Barthelemy'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 Barthelemy?
The spectrum Arcep assigned to the four operators from May 2025 sits in the 900 MHz, 1800 MHz and 2.1 GHz bands, which are used for 2G to 4G service. No 3.5 GHz 5G band has been assigned on the island.
How much data do you need in St Barthelemy?
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 Barthelemy right now:
Are unlimited eSIMs for St Barthelemy really unlimited?
Not always. 371 of the 938 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 Barthelemy 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 Barthelemy?
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 Barthelemy 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 Barthelemy eSIM
Pick the plan, not the brandThe cheapest rate in St Barthelemy today is $0.40 per GB from Yatelo, against a median of $1.63. 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 Barthelemy 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. Expect 5G where the network reaches, 4G everywhere else.
Know what happens when it runs out458 of the 938 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 Barthelemy
Saint Barthelemy left the EU in 2012 and became an overseas territory, so the EU roam like at home rule does not apply. Many European plans bill it at rest of world rates.
Gustaf III airport is tiny and has no SIM shops. Buy in Gustavia or Saint Jean, or load an eSIM before you fly.
Do not assume your EU plan covers this island just because it is French. Some French operators include it in their overseas zone and others do not, so check your tariff sheet or buy a local SIM.
