Good to know
Saint-Barthélemy is a French overseas territory outside the EU roaming zone, so even French and EU mobile plans can bill it as pricey international roaming. A travel eSIM keeps your data costs fixed and predictable.
Unlimited, honestly.

Unlimited plans run at full speed up to a daily fair-use allowance, then at reduced speed until the allowance resets the next day — you're never cut off. Every plan is prepaid: the checkout total is the whole bill, and we never add overage charges.

Hotspot support varies by plan and destination — where it's available for your plan in Saint Barthélemy, it's shown in the plan details before you pay.

The Saint Barthélemy eSIM guide.

Saint-Barthélemy folds Swedish heritage, French style and Caribbean blue into an island of barely eight square miles. Between Gustavia's boutiques and quayside yachts, the Gustaf III runway's famously low landing and beaches like Gouverneur and Saline, an eSIM carries the practical details — villa check-ins, dinner bookings, ferry times and photos straight home.

How it works on the day

Install before you fly and your data goes live the moment you land at Gustaf III (SBH) in Saint-Jean — or step off the St Martin ferry in Gustavia. It runs on local networks like Orange Caraïbe and Digicel, with no physical SIM to swap.

Choosing your days

Most stays run four nights to a week, though peak-season villa lets stretch longer. Match the plan to the trip — a light data pack for a quick escape, or a daily unlimited rate for boat days, remote work and video calls home.

The short version.

A travel eSIM is data only. It sits next to your home SIM, so your number, texts and WhatsApp carry on as normal. Pick unlimited, priced per day, or a fixed bundle of GB if it's mostly maps and messages. Install it on Wi-Fi before you fly — the days only start once it first connects in Saint Barthélemy, and it finds a partner network on its own.

Made for your kind of trip.
