How to install your Saint-Barthélemy eSIM in 3 steps
Gustaf III Airport doesn't sell SIM cards, so anyone who waits until they land ends up making a special trip into Gustavia or Saint-Jean just to get connected. Installing an eSIM beforehand removes that errand entirely.
- Choose your plan and buy online. Match the data allowance to your stay, from a short 1GB/7-day pass for a long weekend around the yachts to a 20GB/30-day plan for an extended stint in Gustavia. Checkout takes a couple of minutes and a QR code arrives by email.
- Install the eSIM profile before you fly. With Wi-Fi connected, scan the QR code from your phone's settings menu to add the new eSIM. Leave your regular SIM in place for calls and texts, and set the new eSIM as the line used for mobile data.
- Land and switch on data roaming for the eSIM. As soon as your plane touches down at Gustaf III, turn on data roaming for the new profile and let your phone pick up Orange Caraïbe's 4G network. There's no shop to find and no passport to show; by the time you've collected your bags, you're already online.
Coverage in Saint-Barthélemy
Three operators keep the island connected: Orange Caraïbe (delivered locally through Dauphin Telecom), SFR Caraïbe, and Digicel. Orange is the strongest of the three, with reliable 4G reaching Gustavia's harbor, Saint-Jean's beach strip, and the main roads that link the island's compact 21 km² of terrain. Because Saint-Barthélemy is so small, populated areas enjoy near-complete signal, and resort and yachting anchorages in particular tend to get a solid connection.
5G has started rolling out, with Orange bringing it to Gustavia, Saint-Jean, and the busier beaches first, but the rollout is still incomplete across the island, so 4G LTE remains the network you can count on everywhere else. Dauphin Telecom and Orange both run physical shops, in Gustavia and Saint-Jean respectively, for travelers who prefer to sort out connectivity in person.
Signal thins out away from the main settlements. Steep hillside trails and narrow valleys, such as those leading down to Colombier Beach, can lose coverage in patches, and the island's mountainous interior isn't as consistently served as the coast. There's also a border quirk worth knowing about: phones near Colombier, in the island's north, sometimes latch onto Saint-Martin's cellular network instead of a local one. Because that's a different country's network, it counts as international roaming and can rack up charges fast unless you manually select a Saint-Barthélemy operator in your phone's network settings.
How much data do you need?
Data needs vary by traveler; here's how usage levels map to Saint-Barthélemy's real plan sizes.
| Usage level | Typical daily use | Suggested plan | Best for |
|---|---|---|---|
| Light | Around 300 MB/day | 1GB / 7 days | Checking maps and messages around Gustavia for a short stay |
| Moderate | Around 750 MB/day | 3GB / 30 days | Social media, browsing, and calls over a week or two on the island |
| Heavy | 1.5 GB/day or more | 10GB / 30 days or 20GB / 30 days | Streaming, video calls, and remote work from Gustavia's harbor or a longer stay |
eSIM vs. home roaming vs. a local SIM
| eSIM | Home carrier roaming | Local prepaid SIM | |
|---|---|---|---|
| Setup | Install the profile before you leave; no store visit or passport needed | Works automatically the moment you land, no setup at all | Requires an in-person visit to a shop in Gustavia or Saint-Jean, since Gustaf III Airport doesn't sell SIM cards |
| ID required | Not required for tourist eSIMs | Not applicable | Passport required at the point of sale to register the SIM |
| Typical cost | From £0.99, with 1GB plans from £0.99 | Highest-tier international rates apply, since Saint-Barthélemy's 2012 status as a French Overseas Country and Territory means EU "roam-like-home" rules don't apply here | Roughly £8-£13 for a prepaid SIM, plus the trip into town to buy it |
| Phone requirements | An eSIM-compatible, carrier-unlocked phone | Whatever your home plan requires | An unlocked phone supporting LTE bands 3 and 20 |
| Best for | Most visitors who want data ready on arrival without hunting for a shop | Very short visits where convenience matters more than cost | Longer stays where a local number is worth the trip and the passport paperwork |
Practical connectivity tips
Buy your eSIM before you travel: Gustaf III Airport has no SIM counter, so anyone arriving without a plan has to head into Gustavia or Saint-Jean first, where Dauphin Telecom and Orange run their shops. If you're settling in for a longer stay and want a local number, a prepaid SIM is worth the trip, just remember to bring your passport, since registration is required at the point of sale.
Around Colombier, in the island's north, keep an eye on your phone's network indicator. It's an area where handsets can unintentionally latch onto Saint-Martin's network instead of a local one, turning a beach walk into an accidental international roaming session. If you notice an unfamiliar network name, switch to manual selection in your settings and pick a Saint-Barthélemy operator instead.
If you're working from a yacht moored off Gustavia, the harbor area has some of the island's strongest signal, useful for video calls or banking on the move. Away from the coast and on steep trails toward Colombier, expect patches of weaker service. For emergencies, the numbers used locally are 15 for medical (SAMU), 17 for police, and 18 for fire; confirm on arrival if you're relying on 112, since its coverage on local networks isn't well documented.

Local info for Saint Barthelemy
Frequently asked questions about eSIMs for Saint Barthelemy
Why are roaming charges so high in Saint-Barthélemy despite it being French?
Saint-Barthélemy became a French Overseas Country and Territory in 2012, which sets it apart from EU outermost regions like Guadeloupe or Martinique. That status means the EU's "roam-like-home" rules don't extend here, so European carriers can charge their highest international rates rather than standard EU roaming prices, and it catches many travelers by surprise.
What is the Colombier roaming risk everyone mentions?
Near Colombier Beach, in the island's north, phones can unintentionally connect to Saint-Martin's cellular network instead of a local Saint-Barthélemy operator. Because that's a different network, it gets billed as international roaming. Manually selecting a local operator in your phone's network settings before heading that way avoids the surprise charge.
Can I buy a SIM card at Gustaf III Airport when I land?
No. SIM cards aren't sold at the airport, so you'd need to travel into Gustavia or Saint-Jean, where Dauphin Telecom and Orange operate shops, before you could get connected. An eSIM installed ahead of time avoids that extra trip.
Do I need my passport to buy a local SIM in Saint-Barthélemy?
Yes. Passport identification is required at the point of sale for any local SIM card registration. Tourist eSIMs don't carry that same requirement, which is one reason many short-stay visitors choose an eSIM instead.
Is 5G available on Saint-Barthélemy yet?
It's still early days. Orange has begun rolling out 5G in Gustavia, Saint-Jean, and the main beach areas, but coverage isn't yet island-wide. 4G LTE remains the network that reliably covers the rest of Saint-Barthélemy, so it's worth not counting on 5G outside the main towns.
Will I get reliable signal for remote work from a yacht in Gustavia harbor?
Gustavia, with its harbor and superyacht anchorage, is one of the better-covered parts of the island for 4G and the emerging 5G service. It's a popular spot for visitors who need dependable data for video calls or banking while moored offshore.
Which network bands do local carriers in Saint-Barthélemy use?
Local operators run on LTE Bands 3 and 20, so any phone you bring needs to support those bands and be carrier-unlocked to get service, whether you're using a local SIM or an eSIM.
Which beaches or areas have the most dependable coverage?
Saint-Jean Beach, the island's most popular stretch of sand, has some of the best cellular coverage, and Grand Saline Beach reports consistent 4G too. Corossol, the fishing village on the western coast, also gets good 4G. Colombier Beach is more secluded and comes with the caveat of possible unintended roaming onto Saint-Martin's network.
How much data should I plan for during a stay?
It depends on how you use your phone. Light use, like maps and messaging, runs around 300MB a day and suits a 1GB/7-day plan; moderate use with social media and calls fits better with a 3GB/30-day plan; heavy use with streaming or frequent video calls calls for a 10GB or 20GB/30-day plan.
Is it worth getting a local SIM instead of an eSIM?
A local SIM makes more sense if you're staying long enough to want a Saint-Barthélemy phone number, and you don't mind the trip into Gustavia or Saint-Jean and bringing your passport for registration. For shorter visits, an eSIM sorted before you fly means you land ready to use the island's French networks without tracking down a Digicel or Orange outlet.
