AlpineSIM eSIM Data Plans for Montserrat

AlpineSIM does not provide any truly unlimited high‑speed data plan for Montserrat. The plans labelled “Unlimited” give a fixed daily allowance, such as 500MB/day for 1 day, up to 5GB/day for 1 day, and after the limit is reached the speed is reduced to the carrier’s reduced speed tier. Because the high‑speed data is capped, these plans are not unlimited in the strict sense.

If you need a larger amount of data, AlpineSIM offers fixed‑data options that can be more cost‑effective for long‑term use. For example, a 20GB plan valid for 30 days costs $112.91 USD, and a 10GB plan also valid for 30 days costs $61.51 USD. These plans provide a set amount of data with no daily caps and maintain high‑speed connectivity until the allowance is exhausted.

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 one single‑country data plan that covers Montserrat. There are no multi‑country plans that include Montserrat. The available plans range in price from about $4.30 to $1, 064.00 and provide data between 500 MB and 20 GB, with validity periods from a single day up to 30 days.
