MeSIM does not provide a truly unlimited data eSIM specifically for the Cayman Islands. All of its Cayman‑Island offerings list a fixed data allowance, such as 500 MB or 1 GB per day for a short‑term “unlimited” plan, or a larger daily allocation that then reduces to 384 kbps once the limit is reached. These plans are therefore capped and not unlimited.
Travelers who need a larger amount of high‑speed data can choose one of MeSIM’s fixed data plans that grant a larger daily or total allowance, such as the 20 GB plan valid for 30 days or the 10 GB plan valid for 30 days. These fixed plans can be more cost‑effective for heavy data users, but they still carry a set data limit rather than unlimited high‑speed connectivity.
