AlpineSIM eSIM Data Plans for Montserrat

AlpineSIM does not provide a truly unlimited high‑speed data plan for Montserrat. All of the plans advertised with “Unlimited” in the name are actually capped, offering a fixed amount of high‑speed data such as 500 MB/day, 1 GB/day, 2 GB/day or 5 GB/day for a set validity period. After the allotted daily limit is reached, the service does not continue to provide high‑speed data at its original speed (no further throttling details are provided).

If a user needs a larger data allowance, AlpineSIM offers fixed data plans that are typically more economical for heavy usage. For example, Montserrat customers can buy a 20 GB plan valid for 30 days for $109.67, a 10 GB plan for 30 days for $59.74, or a 5 GB plan for 30 days for $38.10. These options give a larger total allowance without the daily data caps of the “Unlimited” label.

AlpineSIM does not provide Montserrat eSIM plans that include a local phone number or SMS capability. Only data‑only eSIMs are available for travel to Montserrat.

Customers who need voice or text services can use popular VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection, which allows calls and messaging without a phone number.

AlpineSIM offers 30 single‑country data plans for Montserrat. These plans range in price from $4.29 to $1, 070.23, with data caps between 500 MB and 20 GB and validity periods from one to 30 days. Within its catalog, AlpineSIM provides both fixed data cap plans, which give a set amount of data for the entire validity period, and daily data cap plans, which limit the amount of data that can be used each day. Multi‑country coverage plans are available from the provider, but they are not relevant to the Montserrat‑specific offering.
