AlpineSIM eSIM Data Plans for Caribbean

AlpineSIM does not provide an unlimited data eSIM for Caribbean. The provider’s Caribbean offerings are fixed‑data plans, each with a hard data cap and a specific validity period. Examples of the larger fixed plans are the 10GB / 30 days plan that costs $54.04 USD and the 5GB / 30 days plan that costs $37.77 USD; both include tethering and use 5G networks across 20 Caribbean areas.

Because these plans have a set data allowance, they can be more cost‑effective for most travelers than a pay‑as‑you‑go model. Only if a user is an extremely heavy data consumer would an unlimited plan—if it existed—be worth considering.

AlpineSIM does not provide an eSIM with a phone number or SMS capability for travelers in the Caribbean. Only data‑only plans are available in this region.

Travelers who need voice or text may use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but some Caribbean destinations may block or restrict certain apps or VoIP services. It is advisable to verify that the messaging or calling apps you rely on are accessible in your destination before purchasing.

AlpineSIM’s Caribbean offering is the AlpineSIM Caribbean (20+ areas) – /Day / plan, which covers 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.
