nextSIM eSIM Data Plans for Saint Barthélemy

NextSIM does not provide a true unlimited data eSIM for Saint Barthélemy.
All plans labelled “Unlimited” actually offer a fixed amount of high‑speed data—either 1 GB per day or 2 GB per day, with a reduced speed (512 kbps or 2000 kbps) once the limit is reached. For travelers who need more data without speed throttling, nextSIM offers fixed‑data options such as 10 GB for 30 days, 20 GB for 30 days, or 50 GB for 30 days, which may be more cost‑effective for heavy data users.

nextSIM does not provide a phone number or SMS capability for Saint Barthélemy. Only data‑only eSIM plans are offered by this provider. Travelers can use the data allowance to run VoIP applications such as WhatsApp, Telegram, or iMessage, which support voice calls and messaging over the data connection.
