AlpineSIM does not provide a true unlimited data eSIM for the Caribbean; all plans listed have fixed data caps that remain available at high‑speed rates until the limit is reached. The plans that are marketed as “Unlimited” contain a specified amount of data—such as 500 MB, 1 GB, or 5 GB per day—after which the user can still receive data but at a reduced speed.
Travelers who need more data can choose one of AlpineSIM’s fixed‑allowance eSIMs. For example, a 10 GB plan valid for 30 days costs $54.23 USD, and a 5 GB plan for the same period is priced at $37.91 USD. These larger‑allowance options offer a cost‑effective alternative if a traveler is a heavy data consumer.
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’s “AlpineSIM Unlimited Caribbean (20+ areas) eSIM - /Day / 1” plan includes coverage in 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; the same plan also offers service in various South American and South Atlantic regions, though those are outside the Caribbean.
