iRoamly eSIM Data Plans for Cayman Islands

iRoamly does not provide a truly unlimited eSIM plan for the Cayman Islands.
All of its available plans give a fixed data allowance of 500GB. After the 500GB limit the speed is reduced to 5120kbps, and the plans can be purchased for a range of validity periods, such as 1 day, 3 days, 5 days, 7 days, 10 days, 15 days, 20 days or 30 days. These fixed‑data options can be more cost‑effective for travelers who need large amounts of data but are not heavy‑traffic users.

iRoamly does not offer any Cayman Islands eSIM plan that includes a phone number or SMS functionality. The available plans are data‑only, meaning you can use local data as usual but you will not receive a local number for calls or SMS. If you need to stay in touch while traveling, you can rely on internet‑based messaging and calling apps such as WhatsApp, Telegram, or iMessage, which work over the data connection.

iRoamly offers 75 single‑country data plans and 30 multi‑country data plans that include the Cayman Islands. The single‑country plans are sold at prices ranging from free to about $515 USD and come with data caps from 500 MB up to 500 GB, valid from 1 to 30 days. Multi‑country plans vary similarly in price and data allowance, but they provide coverage across several territories, including the Caymans, with comparable validity periods.
