eSimfly eSIM Data Plans for Saint Martin

eSimfly does not offer an unlimited data eSIM plan for Saint Martin. The provider sells several fixed‑data options for the destination. For example, the Discover Global 20 GB 365 days plan gives 20 GB of data valid for 365 days at $99.45 USD, and the Discover Global 10 GB 180 days plan provides 10 GB for 180 days at $85.00 USD. A smaller 5 GB plan is also available for the French part of Saint Martin for 30 days at $12.24 USD. These fixed‑data plans can be more cost‑effective for most travelers unless an extremely heavy data consumer requires unlimited usage.

eSimfly does not provide a Saint Martin eSIM plan that includes a phone number or SMS capability. Only data‑only eSIMs are available for Saint Martin from this provider. Travelers can still use internet‑based messaging and calling applications such as WhatsApp, Telegram, or iMessage over the data connection, but there is no native phone number or SMS service with the eSIM.

eSimfly lists four single‑country plans for Saint Martin, along with ten multi‑country plans that cover the island as part of a broader Caribbean package. The single‑country options are fixed‑data plans where each plan provides a set amount of data for a set number of days, whereas the multi‑country plans allow daily data usage limits that can be carried across multiple destinations. Across both categories the price ranges from about $4.42 to $99.45, while the data caps vary from 1 GB up to 20 GB, providing a range of options for different usage needs.
