KnowRoaming does not provide an unlimited data eSIM plan for the Cayman Islands. Travelers can instead select from a range of fixed‑data plans that cover the islands. Examples include the Cayman Islands 20 GB 30 days plan at $59.50 USD, the Global 20 GB 30 days for $60.00 USD, the Global 10 GB 30 days for $37.00 USD, the Cayman Islands 10 GB 30 days at $49.50 USD, and the Caribbean 10 GB 30 days for $50.00 USD. These options illustrate the larger data allowances available, but they represent only a subset of the available plans; choosing a fixed data plan can be more cost‑effective for users who consume a significant amount of data, while unlimited usage is not offered.
