eSIM St. Barts: High-Speed Internet for the Jewel of the Caribbean

Welcome to Saint Barthélemy (St. Barts), the epitome of Caribbean luxury. Whether you're docking your yacht in Gustavia, relaxing on the white sands of St. Jean Beach, or hiking to the secluded Colombier Beach, staying connected is part of the lifestyle.

Enjoy seamless connectivity on this exclusive island with Cellesim's St. Barts eSIM plans, starting at just $6.44. Choose from 7 limited and 14 unlimited plans.

CRITICAL WARNING: St. Barts is NOT in the EU Roaming Zone!

This is the most common (and expensive) mistake travelers make:

Saint Barthélemy is a French Overseas Collectivity, but unlike Martinique or Guadeloupe, it is NOT part of the European Union (EU).
This means your "Roam Like at Home" (EU roaming) plan DOES NOT APPLY HERE.
Most carriers (from the US, UK, and Europe) classify St. Barts as a "Rest of World" zone, charging astronomical fees.

A St. Barts eSIM is the only smart way to get affordable data. Get connected the moment you land at Gustaf III Airport (SBH) or arrive by ferry.

Why a Cellesim eSIM is Essential for St. Barts

Avoid the Luxury Trap: Don't let roaming fees ruin your luxury holiday. Our plans are a fraction of the cost.
Instant Connection: Be online as soon as you arrive. Perfect for arranging VIP transfers or restaurant reservations.
Keep Your Home Number: Your eSIM handles the data, so your primary SIM (and your WhatsApp number) remains active for important calls.
Reliable Island Coverage: We partner with top local operators (like Orange Caraïbe or Dauphin Telecom) to ensure excellent 4G/LTE coverage in Gustavia and across the island.

Stay Connected at St. Barts' Exclusive Locations

1. Gustavia

The capital and heart of the island. An eSIM for Gustavia is essential for navigating the luxury boutiques, finding the best restaurants, and sharing photos of the harbor.

2. St. Jean

The island's most popular beach and home to the famous Eden Rock. Stay connected while watching planes land just meters from the sand.

3. Colombier & Toiny

Whether hiking to the remote Colombier beach or surfing at Toiny, stay online to share your adventures in real-time.

Frequently Asked Questions

Got some questions before your Journey? Well here's everything you need to know before you go

Coverage is reliable on the main roads near Toiny and Grand Fond, but expect the connection to be spotty on the rocky hiking trails along the cliffs.

Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing.

Absolutely. Road signs are minimal and streets are winding; reliable data for Google Maps or Waze is vital to navigate your rental Mini Moke to hidden villas safely.

Yes. You will generally have strong signal to share photos of the turtles and yachts, even though Colombier is remote and only accessible by a 20-minute hike or boat.

Yes. Coverage is excellent at St. Jean, allowing you to live-stream or upload videos of the famous low-altitude landings at Gustaf III Airport instantly.

No! This is the #1 roaming trap in the Caribbean. Although St. Barths is a French collectivity, it is NOT part of the European Union. Your EU/French "Roam Like at Home" plan does not apply. Most carriers (including Orange FR) will charge you extremely high international roaming fees, often the most expensive rates they have. A Cellesim eSIM is the only way to get a fixed, prepaid data price and avoid a bill shock.

To give you the best speed and coverage on the island, our eSIM connects to the premium local providers, typically Digicel or Dauphin Telecom (Orange Caraïbe). This ensures you get the fastest available 4G/LTE speeds, whether you are in the capital Gustavia, at Nikki Beach, or at your villa.

Yes, for mobility and security. While luxury villas and 5-star hotels (like Eden Rock or Cheval Blanc) have good Wi-Fi, it is fixed to the property. A personal eSIM gives you a private, secure connection that works everywhere—on St. Jean Beach, at Saline Beach, or when driving around the island. It is essential for using Google Maps on the island's steep, narrow roads.

Yes. The local networks (Digicel/Dauphin) have strong towers that provide excellent 4G/LTE coverage to the main harbors (Gustavia, Anse du Corossol) and the most popular coves and beaches (like St. Jean). You will be able to stay connected from your boat as long as you are close to shore.

This specific plan is valid only for St. Barths. This is a critical point. 99% of visitors land at Sint Maarten (SXM) first and then take a ferry or small plane. Sint Maarten is a separate, dual-country territory. We strongly recommend our Caribbean Regional eSIM, which covers both Sint Maarten and St. Barths, to ensure you are connected from the moment you land.
