SimOptions does not provide an unlimited data eSIM for Montserrat. The provider offers fixed data plans that include 20GB for 15 days, 10GB for 7 days, 5GB for 7 days, 3GB for 3 days, and 1GB for 3 days, with prices ranging from $5.90 to $93.90 USD. These plans give a set amount of high‑speed data that must be used within the specified validity period.
Choosing a fixed data plan can be more cost effective for most travelers, unless a user expects to consume data beyond the highest available allowance.
