No, Textr eSIM does not offer an unlimited data eSIM for the Cayman Islands. The available plans for this destination are fixed data plans with set allowances. For example, the Jamaica + Caribbean 10GB bundle gives 10GB of data for 30 days, while the Jamaica + Caribbean 5GB bundle offers 5GB for 30 days and the 3GB bundle provides 3GB for the same period. If a traveler needs more data, they can choose a higher‑cap bundle, however, no plan provides unlimited data. Selecting a fixed data plan can be more cost‑effective unless the user is an extremely heavy data consumer who would require a larger amount of data.
