Wiiline lists 30 single‑country data plans that include Montserrat and 99 multi‑country plans that cover the island.
The available plans span a price range of roughly $3.99 to $384.99 and a data cap from 490 MB up to 100 GB. Validity periods vary from 1 to 180 days.
Some plans apply a fixed data amount, giving you a clear total of data you can use, while others offer a daily data cap that limits usage each day. Both options allow tethering and have various reduced‑speed thresholds (512 kbps, 500 kbps, 2000 kbps, 1000 kbps) for specific usage conditions.
