nextSIM eSIM Data Plans for Saint Barthélemy

NextSIM does not provide a truly unlimited data eSIM plan for Saint Barthélemy. All plans advertised under the “Unlimited” name have a fixed data allowance—ranging from 1 GB per day up to 2 GB per day for the plus versions—and after the limit is reached the speed is reduced to either 512 kbps or 2000 kbps, depending on the plan.

For travelers who need high‑speed data without such limits, nextSIM offers fixed‑data plans instead. Examples include the 50 GB plan valid for 30 days, the 20 GB plan also valid for 30 days, and the 10 GB plan for 30 days, all of which provide full‑speed data until the cumulative allowance is exhausted. These fixed‑data options can be a more cost‑effective choice unless a user expects to consume data beyond the allocated amount.

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.
