AlpineSIM eSIM Data Plans for Montserrat

AlpineSIM does not provide a true unlimited data eSIM for Montserrat. All plans labeled “Unlimited” in the catalog actually have a daily data cap, such as 500 MB/day, 1 GB/day, or 2 GB/day, after which the speed is throttled to a reduced level.

Instead, AlpineSIM offers fixed‑data plans for travelers who need a larger, predictable allowance. For example, the Montserrat eSIMs with 20 GB, 10 GB, and 5 GB of data are available for 30 days each, and similar fixed‑data options are also sold for the wider Caribbean region. These plans can be a better fit for users who anticipate heavy data usage.

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.
