AlpineSIM eSIM Data Plans for Saint Barthélemy

AlpineSIM does not provide a truly unlimited data eSIM for Saint Barthélemy; every available plan lists a specific data cap such as 1GB, 2GB, 5GB, 10GB, or 20GB. Some plans are marked “Unlimited”, but they still contain a fixed data allowance and have no unthrottled data after the cap is reached.

Travelers can choose from fixed‑data options instead. For example, AlpineSIM offers a 20GB plan for 30 days at $12.74 USD and a 10GB plan for 30 days at $6.02 USD, both at 5G speed. These fixed‑data plans may be more cost‑effective for long‑term use or heavy data consumption.

AlpineSIM does not provide an eSIM for Saint Barthélemy that includes a phone number or SMS capability. Only data‑only plans are sold for this destination. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages, but a traditional phone number or SMS service is not available.
