Can I expect free roaming in St. Barths using my French or other European Union (EU) SIM card?

It's crucial to understand that while St. Barths is a French overseas collectivity, it operates outside the European Union's 'Roam Like at Home' regulations. This means your standard EU or French mobile plan will not provide free roaming here. Most European carriers, including those from France, will levy significant international roaming charges for data, calls, and texts. To avoid unexpected bills, eSIMAdventures highly recommends a dedicated eSIM for St. Barths, offering transparent and affordable data.
