abesteSIM does not provide an unlimited data eSIM for the Cayman Islands. The available options are fixed data plans that must be used within a set validity period. For example, abesteSIM offers a 10GB plan valid for 30 days, a 5GB plan also valid for 30 days, a 3GB plan for 30 days, a 2GB plan for 15 days, and a 1GB/day plan for a single day. All of these plans are available on 5G networks, allow tethering, and include a reduced speed of 128kbps once the data allowance is exhausted.
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 an unlimited plan.
