AlpineSIM eSIM Data Plans for Saint Barthélemy

AlpineSIM does not provide a truly unlimited data eSIM for Saint Barthélemy. All of its “Unlimited” plans are actually capped, offering a fixed amount of high‑speed data – for example, a 10 GB plan for 1 day or a 20 GB plan for 30 days – after which the data allowance ends. Travelers who need more high‑speed data can instead choose from these large fixed‑data options, which may be more cost‑effective unless they require continuous, uninterrupted usage.

AlpineSIM does not provide a Saint Barthélemy eSIM that includes a phone number or SMS capability. All AlpineSIM plans for the island are data‑only offerings. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should confirm that these services are accessible in Saint Barthélemy before purchasing.

AlpineSIM provides a sizable selection of plans for Saint Barthélemy, with 46 options that cover the island exclusively and an additional 52 plans that include Saint Barthélemy as part of a broader multi‑country package. The single‑country and multi‑country plans share similar pricing and data structures. Prices across the catalogue range from about $0.79 to $1, 178.32, while data caps span from 1 GB up to 20 GB. Validity periods can be as short as one day or extended up to a full year. AlpineSIM offers both fixed‑data‑cap packages—28 in total—and daily‑data‑cap packages—70 in total—so travelers can choose whether they prefer a predetermined data budget or a daily allotment that rolls over. Additionally, most plans allow tethering, giving users the flexibility to share the connection with multiple devices.
