eSimfly eSIM Data Plans for Caribbean

eSimfly does not provide a true unlimited data eSIM for the Caribbean. The plan titled Caribbean Islands Unlimited 7 Days lists a data cap of 3 GB per day; after reaching that limit the plan’s speed is either throttled or the data stops, so it is not a no‑limit high‑speed plan.

Instead, eSimfly offers fixed data plans that cover the Caribbean. For instance, the Discover Global 20 GB 30 days plan gives 20 GB for 30 days at $40.88 USD, and the Discover Global 20 GB 365 days plan offers the same data amount for 365 days at $76.05 USD. These options give travelers a clear data allowance and can be more cost‑effective unless a user requires a high‑volume, unlimited data solution.

eSimfly does not offer Caribbean eSIM plans that include a phone number or SMS capability. The provider’s Caribbean offerings are data‑only, so there is no way to make or receive standard voice calls or text messages via the device’s native telecom network.

Travelers who need voice or messaging can still use internet‑based services such as WhatsApp, Telegram, and iMessage, which work over the data connection supplied by the eSIM.

eSimfly offers several eSIM plans that cover a broad array of Caribbean destinations, including the Discover Global, Caribbean (20+ areas) and Caribbean Islands plans, each of which lists a set of Caribbean territories ranging from small island states to U.S. and French overseas territories. Across these plans the following countries and territories are covered: Anguilla, Aruba, Antigua and Barbuda, Barbados, Bahamas, Bonaire, Sint Eustatius, Saba, Saint Barthélemy, Saint Martin, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Curaçao, Dominica, Dominican Republic, Guadeloupe, Grenada, Haiti, Jamaica, Martinique, Cayman Islands, Montserrat, Puerto Rico, Sint Maarten, Turks and Caicos Islands, Trinidad and Tobago, and British Virgin Islands. The Discover Global plan in particular also extends coverage beyond the Caribbean into numerous other parts of the world, while the Caribbean‑focused plans concentrate solely on the listed Caribbean destinations.
