eSIMPhoney does not provide an unlimited data eSIM for Montserrat. All of their available plans for Montserrat have fixed data caps, such as the 50GB plan valid for 180 days, the 20GB plan valid for 90 days, and the 10GB plan valid for 30 days.
Travelers can choose one of these fixed‑data options, which may offer a more cost‑effective solution for most users unless they anticipate extremely heavy data usage. The plans listed above are examples of the larger data allowances offered; additional fixed‑data plans are also available in eSIMPhoney’s catalogue.
