RedSim does not offer a true unlimited data eSIM for the Cayman Islands. The only plan that carries “Unlimited” in its name is the Caribbean Unlimited 7 Days, which provides 3GB of high‑speed data per day and then throttles the speed to 1000kbps for the remainder of the day.
Travelers who need more data without throttling can choose from RedSim’s fixed‑data bundles. For example, the Cayman Islands 20GB 30 Days plan supplies 20GB of high‑speed data for 30 days at a price of $106.26 USD, and the Global 20GB 30 Days plan delivers the same capacity for 30 days at $53.59 USD. These fixed plans are generally more cost‑effective for most users unless extremely heavy data consumption is anticipated.
