GulfData does not provide a truly unlimited data eSIM for the Cayman Islands. The plans that carry the “Unlimited” name give 1 GB per day at full speed and then throttle to 512 kbps, so they are not unlimited in the sense of offering high‑speed data without limits.
Travelers who need a larger, unthrottled data allowance can choose GulfData’s fixed data plans, such as the 20 GB plan valid for 30 days or the 10 GB plan also valid for 30 days. These fixed data plans offer a set amount of high‑speed data for the entire validity period and can be more cost‑effective unless the user is an extremely heavy data consumer.
