AlpineSIM eSIM Data Plans for Montserrat

AlpineSIM does not provide a true unlimited‑data eSIM for Montserrat. The plans listed with “Unlimited” in their names actually offer a fixed amount of high‑speed data (for example, 500MB /day, 1GB /day, 2GB /day, 5GB /day, etc.) and no plan has an unlimited data cap. After the specified data allowance is used, the speed is throttled.

If a traveler wants a larger data allowance, AlpineSIM offers fixed‑data plans such as 5GB for $33.23 USD, 10GB for $51.98 USD, and 20GB for $99.69 USD, all valid for 30 days. These options can be more cost‑effective for users who need a substantial amount of data without the friction of a data‑limit‑based throttling rule.

AlpineSIM does not provide a Montserrat eSIM that includes a phone number or SMS capability. Travelers who need a local number will have to use an alternative method. While the plans are data‑only, popular VoIP applications such as WhatsApp, Telegram and iMessage can typically be used over the data connection for calls and messaging, but some destinations may block or restrict these services, so it is advisable to check the availability of the apps you rely on in Montserrat before purchasing.

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.
