AlpineSIM eSIM Data Plans for Caribbean

AlpineSIM does not provide a truly unlimited data eSIM for Caribbean. The plans that carry the name “Unlimited Caribbean” actually contain a daily data cap of 500 MB, 1 GB, or 5 GB and remain valid for a set number of days ranging from 1 to 30. Once the daily limit is reached, speeds are throttled.

Instead, AlpineSIM offers fixed‑data eSIM options that may suit heavy data users. For example, a 10 GB plan is available for 30 days at $55.50 USD, while a 5 GB plan for the same period costs $39.90 USD. These fixed‑data plans provide a predictable amount of high‑speed data without daily restrictions.

AlpineSIM does not provide Caribbean eSIM plans that include a local phone number or the ability to send or receive SMS. Only data‑only eSIMs are offered for travel in the Caribbean, with no inbound or outbound voice or text capabilities. Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection, to make calls and send messages without a local phone number.

AlpineSIM Unlimited Caribbean (20+ areas) eSIM – /Day /1 includes coverage in the Caribbean for 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, Saint Vincent and the Grenadines, and the British Virgin Islands.
