Avelis eSIM does not provide an unlimited data eSIM for Martinique. All of the plans listed for Martinique have a hard data cap, with the largest offering 20GB for a 30‑day validity period.
Travelers who need a large amount of data can choose one of the fixed data plans, such as the 20GB/30‑days plan or the 10GB/30‑days plan. These plans give a clear data allowance and a set validity window, which can be more cost‑effective for most users unless they are extremely heavy data consumers.
