JamboSim eSIM Data Plans for Caribbean

JamboSim does not provide a truly unlimited high‑speed data plan for the Caribbean. The plan titled “eSIM JamboSim Caribbean Unlimited / 7 Days” gives only 3 GB per day and reduces speed to 1 000 kbps after the daily allocation is reached, so it is not truly unlimited.

Travelers looking for higher data allowances can choose from fixed data plans instead. For example, the “eSIM JamboSim Caribbean 10 GB / 30 days” plan costs about $42.99 USD, and the “eSIM JamboSim Global 20 GB / 30 days” costs roughly $40.99 USD. These plans offer a larger, capped amount of high‑speed data that may be more cost‑effective for most users.

Yes, JamboSim sells eSIM plans for the Caribbean that include a local phone number and the ability to send SMS. The price range of the available plans is from $11.99 to $105.99 USD, and the validity period varies from 7 days up to 365 days. Each plan provides a dialing code of +1, which is the North American Numbering Plan used by many Caribbean countries. Calls can be made outbound and SMS can be sent outbound, but inbound voice and SMS are not included.

Users who need to receive calls or messages should check the current plan details directly with JamboSim before purchasing, as the plans listed above only support outbound telephony and SMS.

The eSIM JamboSim Caribbean plan covers Antigua and Barbuda, Aruba, Barbados, Saint Barthélemy, Bonaire, Sint Eustatius, Saba, Bahamas, Curaçao, Dominica, Grenada, Guadeloupe, Haiti, Jamaica, Saint Kitts and Nevis, Cayman Islands, Saint Lucia, Saint Martin, Montserrat, Puerto Rico, Sint Maarten, Turks and Caicos Islands, Trinidad and Tobago, and Saint Vincent and the Grenadines. The broader eSIM JamboSim Global and Global+ plans include that same Caribbean coverage and add Anguilla and the British Virgin Islands as well, so travelers using those plans receive local coverage in the additional territories mentioned.
