The short answer
Six travel eSIMs sell data for Saint Barthélemy, St Barts to most visitors, and get most of the traffic for this search. I priced all six on the same day, for a long weekend in Gustavia, a week on the beaches, two weeks and a month, and I read the fine print on unlimited. The island is French but outside the EU, so an EU phone plan does not cover it by law. Here is where each one wins.
Unlimited data at full speed for 2 weeks at $18.99 or 30 days at $35.99, nothing renews. Airalo asks $65 for 15 days and $99 for the month.
3 GB for 15 days at $8 on its Saint Barthélemy plan, and 10 GB for 30 days at $19 on its Best Caribbean regional plan.
50 GB for 30 days at $39 and 20 GB at $33, on Digicel. Nomad sells no unlimited here.
$19.50 on Digicel, 3 GB a day at full speed, then 1 Mbps. Holafly is 40 cents more. Ringo Light's 2 weeks costs less than either, 51 cents under Airalo, though it is not a 3-day plan.
Prices read on 31 October 2026: Airalo, Holafly, Saily, Nomad, Ubigi on their own sites or listings, Ringo Light from its catalogue. All in US dollars unless stated. Treat every number as a snapshot.

The prices, charted
US dollars, 31 October 2026. The rivals sell 15 days, Ringo Light 2 weeks. Ubigi's bar is its Caribbean regional plan: 30 GB at full speed, then 2 Mbps. Saily and Nomad sell no two weeks of unlimited here.
The 30-day plan at each brand. Ringo Light is unlimited data at full speed. Saily's month is its Global plan, 30 GB at full speed, then slowed. Ubigi's is its Best Caribbean regional plan, 60 GB, then 2 Mbps. Nomad sells no unlimited.
Holafly sells no buckets. Ringo Light sells no bucket either: its 2 weeks is unlimited and lasts 2 weeks, not 30 days. Ubigi's 10 GB is its Best Caribbean regional plan.

What to do in Saint Barthélemy, and what your phone needs for it
Eight places most first trips include, from the harbour at Gustavia and the famous runway at Saint-Jean to the beaches at Colombier, Saline and Flamands, with the one thing your data does for you at each. The island is small enough to cross in a short drive, but the roads are steep and the signal thins in the far coves.
If you want unlimited for two weeks or a month: Ringo Light
Most people come to Saint Barthélemy for a week or two of beaches, boats and dinners in Gustavia. Some stay a season, for work in the villas, hotels and yards. Data here is dear, and I read every rival row with that in mind: for 15 days of unlimited, Airalo asks $65 and Holafly $67.90. Ubigi's Caribbean regional plan, which covers the island, asks $75 for 30 GB at full speed, then 2 Mbps. Saily and Nomad sell no two weeks of unlimited. Ringo Light charges $18.99 for 2 weeks, nothing renews.
For a month the gap is wider. Saily's Global plan costs $59.99 for 30 GB at full speed, then slowed. Ubigi's Best Caribbean month is $69 for 60 GB, Airalo $99 and Holafly $133.50. Ringo Light charges $35.99 for 30 days.
Read what unlimited means before you pick. Airalo gives 3 GB a day at full speed, then 1 Mbps. Ubigi and Saily give a fixed amount, then slow you down. Holafly states no daily cap for your own phone and limits sharing to 1 GB a day. Ringo Light is unlimited data at full speed for the whole 7 days, 2 weeks or 30 days.
For a short trip, Ringo Light sells no 3-day plan. Airalo sells 3 days of unlimited at $19.50 and Holafly at $19.90, so on this island Ringo Light's 7 days at $5.99 costs less than either brand's 3 days. For a week, Ringo Light's 7 days at $5.99 costs less than Airalo's $36, Holafly's $36.90 and Ubigi's $27 for 20 GB at full speed on its Best Caribbean plan.
Coverage on a small, hilly island, and EU roaming
Saint Barthélemy is small and steep, and the travel eSIMs here name one network: Airalo, Holafly, Nomad and Ubigi all ride Digicel. Saily does not name its network on its listing. Holafly's own page says coverage covers most populated areas and beaches, and may be weaker in secluded coves, on high ground, on some boat trips, and in parts of the Colombier, Gouverneur and Saline beaches. I would download offline maps before you walk to Colombier or drive out to the south coast.
The island is French and uses the euro, but it left the European Union on 1 January 2012 and is now an overseas country and territory associated with it. The EU roaming rules, roam like at home, apply only inside the EU, so they do not cover Saint Barthélemy. Whether a French or other EU plan includes it is up to the operator, so I would read your plan's price list before you fly. A Europe travel eSIM does not cover it either, and neither does Ringo's Europe trip.
If you want a data bucket: Ubigi or Nomad
- Ubigi, $8 for 3 GB. Its Saint Barthélemy plan, 3 GB for 15 days, the cheapest way to cover a short stay. Its Best Caribbean regional plan sells 10 GB for 30 days at $19 and 3 GB for 30 days at $9.
- Nomad, $23 for 10 GB. 20 GB for 30 days at $33 and 50 GB for 30 days at $39, the most data for the money here, on Digicel. 3 GB for 30 days is $12. Nomad sells no unlimited for Saint Barthélemy.
- Airalo, $39 for 10 GB. Its Barnet plan: 20 GB for 30 days at $49 and 5 GB at $27. The app is needed.
- Saily, $45.99 for 10 GB. Its Saint Barthélemy plan; 5 GB is $33.99. Its listing is from July; saily.com refused the fetch, so I did not re-read it.
- ✓Ringo Light, no buckets. Ringo Light's 2 weeks is unlimited for $18.99, one cent under Ubigi's 10 GB, but Ubigi's lasts 30 days and Ringo's 2 weeks. Its 30 days is unlimited for $35.99, $2.99 more than Nomad's 20 GB at $33. For 3 GB, Ubigi at $8 and Nomad at $12 cost less than anything Ringo sells. I would rather you read that here than at checkout.
What Ringo Light is
I write for Ringo, so weigh that. Ringo Light is the data eSIM sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Saint Barthélemy it sells three trips, all unlimited data at full speed with no speed cap: 7 days at $5.99, 2 weeks at $18.99 and 30 days at $35.99. Nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
Ringo's Caribbean trip and Europe trip do not cover Saint Barthélemy, so this is the Ringo Light to buy for it. It covers Saint Barthélemy only, not Saint Martin, Sint Maarten or Anguilla, where most flights and ferries connect.
The card to buy it is further up this page, just after the side-by-side table.

None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
