RoameSIM eSIM Data Plans for Montserrat

RoameSIM does not provide a truly unlimited data eSIM for Montserrat. The only plan that uses the word “Unlimited” – the Caribbean Islands – Unlimited – 7 days – actually grants 3 GB of high‑speed data per day, after which the speed is throttled to 1000 kbps.

Instead, RoameSIM offers fixed‑data options such as the Discover Global – 20 GB – 30 days plan and the Caribbean Islands – 10 GB – 30 days plan, both of which give high‑speed data for a set amount of time without a daily limit. Those fixed‑data plans are generally more cost‑effective unless the traveler needs a very large quantity of data.

RoameSIM offers eSIM plans for Montserrat that include a phone number and SMS capability. The plans range in price from $21.00 USD for 1 GB of data valid for 7 days to $124.60 USD for 20 GB of data valid for 365 days. Each plan provides a phone number with dialing code +1, supports inbound and outbound voice calls, and allows both inbound and outbound SMS messages.

Users can verify the specific details and any updates directly with RoameSIM, especially if they need confirmation that the phone number is a local Montserrat number or if they have particular calling or texting requirements.

RoameSIM provides a total of 4 single‑country plans and 24 multi‑country plans for travelers to Montserrat. The available plans range in price from about $2.40 to $124.60 and carry data caps between 200 MB and 20 GB, with validity periods spanning from 3 to 365 days. Most plans offer a fixed data amount per validity period, while a single daily‑data‑cap option is also available for users who prefer a cap that accrues each day.
