MobiMatter eSIM Data Plans for Saint Barthélemy

MobiMatter does not provide an unlimited‑data eSIM for Saint Barthélemy. All of the available plans for the island have a fixed data cap, the largest being the Best World 25 GB 90 days plan. Other options include a 20 GB plan for 30 days, a 10 GB plan for 30 days, and a 5 GB plan for 30 days. Because these plans are capped, they can be more cost‑effective for most travelers unless someone is an extremely heavy data user that would require an unlimited package.

MobiMatter does not provide eSIM plans that include a phone number or SMS for Saint Barthélemy. Travelers who need voice or text service will have to rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.
