Skratch does not provide a truly unlimited data eSIM for Saint Lucia. The plans that carry “Unlimited” in their name actually give a fixed amount of high‑speed data each day—2 GB/day for the Saint Lucia Unlimited plans and 1 GB/day for the Caribbean Unlimited plans—and after that limit is reached the speed is throttled to 500 kbps or 512 kbps, respectively.
If you need a larger, unthrottled data allowance, Skratch offers fixed data plans such as 20 GB for 30 days at $116.99 USD, 10 GB for 30 days at $63.99 USD, or 5 GB for 30 days at $34.99 USD. These fixed data plans can be more cost‑effective for most travelers unless you are an extremely heavy data user.
