No, WonderConnect does not provide an unlimited data eSIM specifically for Sint Maarten. The provider offers only fixed‑data plans for the destination, the largest of which provide 20GB of data valid for 30 days. Other options include 10GB or 5GB data bundles for the same validity period. Travelers who require a larger amount of data can choose one of these fixed plans, which can be more cost‑effective than a pay‑as‑you‑go model unless they anticipate extremely heavy usage.
