Roambit does not provide an unlimited‑data eSIM for Saint Martin. The only plans offered for the island are fixed data bundles that must be used within a 30‑day validity period, with available options of 10GB, 5GB, or 3GB for $59.99 USD, $34.99 USD, and $24.99 USD respectively. Travelers who need more than these caps can consider purchasing a larger fixed bundle or, if available, a Pay‑as‑you‑go plan elsewhere, but with Roambit the largest inclusive allowance for Saint Martin is 10GB for 30 days. Choosing a fixed data plan can be more cost effective unless the user is an extremely heavy data consumer, in which case a different provider with unlimited data may be preferable.
