Lumbus does not provide an unlimited data eSIM for the Cayman Islands. All of its Cayman‑Island plans have a fixed data cap. For example, the Cayman Islands 20GB 30Days plan offers 20GB of high‑speed data for 30 days, the Cayman Islands 10GB 30Days plan offers 10GB for 30 days, and the Cayman Islands 5GB 30Days plan offers 5GB for 30 days. Each of these plans includes tethering and is valid for 30 days.
Choosing a fixed data plan can be more cost‑effective for most travelers unless they are extremely heavy data users. Lumbus also offers Caribbean (20+ areas) plans that include 5G coverage and the same 10GB and 5GB data amounts for 30 days, providing additional coverage beyond the Cayman Islands.
