nextSIM’s eSIM offerings for Montserrat are labeled “Unlimited” but they only provide high‑speed data up to 1 GB per day (or 2 GB per day for the Plus tier). After that limit is reached, the connection is throttled to 512kbps or 2000kbps respectively, so the plans are not truly unlimited.
Travelers who need a consistent, unrestricted amount of data can choose a fixed‑data plan instead. Examples include the 20GB 30 Days Montserrat plan priced at $91.93 USD and the eSIM GLOBAL 50GB 30Days Premium plan for $1, 283.31 USD, both offering a set amount of data without post‑cap throttling. These fixed plans can be more cost‑effective for users who expect to consume a large amount of data during their stay.
