AlpineSIM does not provide a truly unlimited‑data eSIM for the Caribbean; all plans that carry the “Unlimited” label are fixed‑cap packages. The provider offers a range of on‑demand plans that deliver a set amount of high‑speed data and, once the cap is reached, the speed will be throttled. For example, the plans include 500MB/day, 1GB/day, 5GB/day, and 10GB packages with validity periods from 1 day up to 30 days.
Travelers who need more data without the worry of a speed reduction can choose from the fixed‑data options, such as the 5GB or 10GB plans that last 30 days. These plans are often more cost‑effective for heavier data users than repeatedly buying short‑term “Unlimited” packages.
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.
