Skyalo does not provide an unlimited data eSIM plan for the Cayman Islands. All of its Cayman Islands offerings are fixed data plans with a hard cap. Examples include a 20GB plan valid for 30 days, a 10GB plan also valid for 30 days, and a 10GB/day plan that is usable for 1 day.
Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user is an extremely heavy data consumer who would benefit from a truly unlimited option.
