Movisim does not provide a true unlimited data eSIM for Montserrat. All of its plans for the island have a fixed data cap, even those whose names include the word “Unlimited.” For example, the Montserrat 20.5GB – 30‑Day eSIM offers 20GB of high‑speed data for 30 days, while the Montserrat 10.2GB – 30‑Day eSIM gives 10GB for the same period.
If a traveler needs a large amount of data, these fixed‑data plans can be a cost‑effective choice. The 1‑Day “Unlimited” plans, such as the Montserrat 2.0GB/day (Unlimited) – 1‑Day eSIM, provide a daily data allowance that is capped at 2GB and then throttled to 512kbps once the limit is reached. These options are suitable for short stays or moderate usage, but they do not offer unlimited high‑speed data.
