PRIeSIM eSIM Data Plans for Cayman Islands

PRIeSIM does not provide a truly unlimited data eSIM for the Cayman Islands. The only plan with “Unlimited” in its name – Caribbean Islands Unlimited · 7 days – offers 3 GB of high‑speed data per day and then reduces the speed once the daily limit is exceeded; it does not give an unlimited data allowance. Travelers who need larger amounts of data can choose one of PRIeSIM’s fixed data plans, such as the Discover Global 60 GB plan valid for 125 days or the Discover Global 20 GB plan valid for 30 days. These options give a specified high‑speed data allowance and can be used over the duration of their validity period.

PRIeSIM does not offer Cayman Islands eSIM plans that include a phone number or SMS capability. Travelers who need local calling or text messaging will need to rely on data-only plans and use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. Some destinations may restrict access to certain VoIP services, so it is advisable to verify that the apps you rely on are available in the Cayman Islands before purchasing a plan.

PRIeSIM provides 6 single‑country data plans and 19 multi‑country plans for the Cayman Islands. Among the plans offered there is a single daily data cap option, where the data allowance resets every day, and the remaining 24 plans are fixed‑data caps applied for the length of the validity period. Prices for the Cayman Islands range from about $2.28 to $236.26, while the data caps cover a spectrum from 200 MB up to 60 GB.
