ZenSim does not provide a high‑speed unlimited data eSIM for Saint Barthélemy. All of the plans listed for Saint Barthélemy have a fixed data cap, such as 20GB or 10GB, or a daily limit of 3GB per day after which the speed is throttled to 1000 kbps.
Travelers who need more data can choose from ZenSim’s fixed data plans, for example the Caribbean+ 20GB‑15 days plan for 70.20 USD or the Caribbean+ 10GB‑15 days plan for 42.30 USD. These packages must be used within their validity period, and after the allocated data is consumed the speed may be reduced. For most users a fixed data plan is typically more cost effective unless extremely heavy data consumption is expected.
