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.

Frequently Asked Questions
WestESIM is compatible with most flagship smartphones released since 2018-2019, reflecting the widespread adoption of eSIM technology. This includes popular models like the iPhone XS and all subsequent models, Google Pixel 3 and newer, and the Samsung Galaxy S20 series and its successors. Beyond smartphones, an increasing number of tablets, smartwatches, and even laptops now support eSIM. The quickest way to verify compatibility is to check your device's settings for an 'Add eSIM' or 'Add Cellular Plan' option.
Almost every premium smartphone released since 2019 is equipped with eSIM functionality, making them perfectly suited for WestESIM's international travel solutions. This includes a broad range of devices such as the iPhone XS and newer generations, Google Pixel 3 and subsequent models, and the Samsung Galaxy S20 series and its latest iterations. Additionally, many newer mid-range devices also feature eSIM support. If your phone's settings show an option to 'Add eSIM' or 'Add Cellular Plan,' it's likely ready for seamless global connectivity with WestESIM.
It is important to note that while St. Barths maintains a special relationship with France, it falls outside the European Union's 'Roam Like at Home' zone. Consequently, your standard French or EU mobile plan will likely incur significant roaming charges for data usage. Many European carriers, including major ones like Orange France, apply premium rates. To avoid unexpected costs and ensure seamless, high-speed connectivity, WestESIM offers dedicated plans for St. Barths that provide transparent and cost-effective data.
The WestESIM plan tailored for St. Barths is specifically optimized for use within that island's geographical boundaries. As most visitors arrive via Sint Maarten (SXM) before transferring, it's crucial to understand that Sint Maarten is a distinct territory with its own network infrastructure. Your St. Barths eSIM will not provide connectivity there. For uninterrupted service from the moment you land at SXM, we advise considering a regional plan or a separate eSIM that includes Sint Maarten.
For exceptional coverage and speed on St. Barths, WestESIM partners with the island's premier network operators. Our eSIMs typically connect to robust networks such as Digicel and Dauphin Telecom (Orange Caraïbe).

You can rely on a consistent and strong signal for all your digital needs.
For unparalleled mobility and security, WestESIM's mobile data offers a distinct advantage over hotel or villa Wi-Fi, even at prestigious establishments like Eden Rock or Cheval Blanc. While property Wi-Fi is excellent within its confines, our eSIM provides a private, secure, and consistently fast connection that extends across the entire island. Enjoy reliable speeds for work or leisure whether you're dining in Gustavia, exploring Saline Beach, or navigating to your next destination. This ensures your connectivity remains uninterrupted and protected.
