eSimfly eSIM Data Plans for Caribbean

eSimfly does not provide a truly unlimited data eSIM for Caribbean destinations. The only plan titled “Unlimited” actually offers 3 GB of high‑speed data each day and is valid for 7 days; after the daily allowance is reached a reduced speed is applied, though the specific throttled speed is not listed.

For travelers who need large amounts of data, eSimfly offers fixed‑capacity plans such as the Caribbean Islands 10 GB 30 days plan, which supplies 10 GB for 30 days, and the Discover Global 20 GB 365 days plan, which supplies 20 GB for 365 days. These alternatives may be more cost‑effective for most users compared with the capped “Unlimited” offering.

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’s Caribbean eSIM portfolio highlights a number of plan names, each covering a specific set of islands. The Discover Global plan is the most extensive, providing coverage for Antigua and Barbuda, Anguilla, Aruba, Bahamas, Barbados, Bonaire, Sint Eustatius, Saba, Saint Barthélemy, Curaçao, Dominica, Dominican Republic, Grenada, Guadeloupe, Haiti, Jamaica, Saint Kitts and Nevis, Cayman Islands, Saint Lucia, Saint Martin, Martinique, Montserrat, Puerto Rico, Sint Maarten, Turks and Caicos Islands, Trinidad and Tobago, Saint Vincent and the Grenadines, and the British Virgin Islands. The Caribbean Islands plan covers the same core group and includes Puerto Rico. The Caribbean (20 + areas) plan adds the British Virgin Islands and Puerto Rico to its roster of Antigua and Barbuda, Anguilla, Barbados, Curaçao, Dominica, Dominican Republic, Grenada, Guadeloupe, Jamaica, Saint Kitts and Nevis, Cayman Islands, Saint Lucia, Montserrat, Puerto Rico, Sint Maarten, Turks and Caicos Islands, and Saint Vincent and the Grenadines. A second entry under Discover Global lists Aruba, Bahamas, Curaçao, Dominican Republic, Guadeloupe, Jamaica, Puerto Rico, Sint Maarten, Trinidad and Tobago, and the British Virgin Islands.
