nextSIM eSIM Data Plans for Saint Barthélemy

nextSIM does not provide a true unlimited high‑speed data eSIM for Saint Barthélemy. Plans that carry “Unlimited” in their names actually allow 1GB per day or 2GB per day, after which the speed is throttled to 512 kbps or 2000 kbps respectively. Because of this fixed cap, the plans are not truly unlimited for high‑speed usage.

If a traveler prefers a higher data allocation without the daily limits, nextSIM offers fixed‑data plans such as 5GB, 10GB, 20GB, and 50GB for 30 days. These plans allow the full data allowance at standard speeds until the quota is exhausted, and they may be more cost‑effective for regular or moderate 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.
