ZenSim eSIM Data Plans for Saint Barthélemy

ZenSim does not provide a truly unlimited data eSIM for Saint Barthélemy. The only plan that uses “Unlimited” in its name supplies 3 GB of high‑speed data per day, after which the network will likely throttle speed, so it is not an unlimited data offering.

Travelers can instead purchase fixed‑data plans such as the 20 GB plan valid for 15 or 30 days or the 10 GB plan for 15 or 30 days. These plans give a larger data allowance and may be more cost‑effective for users who consume moderate to heavy data during their stay.

ZenSim does not provide a Saint Barthélemy eSIM that includes a phone number or SMS service. The provider only offers data‑only plans for that destination. Travelers can use WhatsApp, Telegram, and iMessage over the data connection for calls and messaging.

ZenSim offers 14 single‑country data plans in Saint Barthélemy, with no multi‑country options available. The plans are priced between $10 and $117, provide between 1 GB and 20 GB of data, and are valid from 5 to 30 days. Thirteen of these plans are fixed‑data‑cap offerings that deliver a set amount of data for the entire validity period, while the remaining plan applies a daily data cap that limits the amount usable each day but allows the total to be consumed gradually over the validity. All plans permit tethering.
