RedSim eSIM Data Plans for Montserrat

RedSim does not provide a truly unlimited high‑speed data plan for Montserrat. All of its plans for the island have a hard data cap; the highest per‑day allowance is 3 GB a day on the Caribbean Unlimited 7 Days plan, after which the speed is throttled to 1000 kbps.

Travelers can instead choose large fixed data plans such as the Global 20 GB 30 days plan or the Montserrat 20 GB 30 days plan, which offer 20 GB of high‑speed data for 30 days and can be more cost effective for users who need substantial data but not a true unlimited package.

RedSim does not provide an eSIM with a phone number or SMS capability for Montserrat. The only plans available from this provider in that destination are data‑only. Travelers who need to make voice calls or send SMS can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Montserrat before purchasing.

To travel to Montserrat, RedSim offers a total of 15 single‑country data plans and 10 multi‑country plans that include Montserrat as part of the coverage. Plan prices range from about $6.15 to $376.20 USD, with data caps varying from 1 GB up to 20 GB. The provider’s selection includes both fixed‑data‑cap options and daily‑data‑cap plans, giving users flexibility whether they need a set amount of data for the duration of their stay or a daily allowance.
