nextSIM eSIM Data Plans for Saint Barthélemy

nextSIM does not provide a truly unlimited high‑speed eSIM for Saint Barthélemy. Plans that use the word “Unlimited” in their name actually have a fixed data cap and switch to a reduced speed after that limit. For example, eSIM Unlimited Standard 1 Day offers 1 GB of high‑speed data and then throttles to 512 kbps, while eSIM Unlimited Plus 1 Day gives 2 GB before the speed is cut to 2000 kbps. These caps also apply to the longer‑validity variants, such as the 30‑day “Unlimited Standard” plan that still provides only 1 GB per day.

If a user needs more data and prefers a plan that stays at full speed until the cap, nextSIM offers several fixed‑data options. The 50 GB 30‑day plan costs $143.58, the 20 GB 30‑day plan is $63.58, and the 10 GB 30‑day plan is $35.58. These plans give a larger data allowance at the same network speed until the limit is reached, and may be more cost‑effective for travelers who use a substantial amount of data.

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.
