Roambit does not provide an unlimited data eSIM for Saint Barthélemy. The available options are fixed data plans that must be used within a set validity period. For example, Roambit offers a 10GB plan valid for 30 days, a 5GB plan also valid for 30 days, and a 3GB plan with the same 30‑day validity. All of these plans operate on 5G, allow tethering, and cover Saint Barthélemy.
Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user is an extremely heavy data consumer who would benefit from a truly unlimited plan.
