eSimfly eSIM Data Plans for Cayman Islands

eSimfly does not offer a true unlimited data eSIM for the Cayman Islands. The plan named Caribbean Islands Unlimited 7 Days contains a cap of 3 GB per day and reduces speed to 1024 kbps once the limit is reached, so it is not an unlimited high‑speed plan.

Instead, eSimfly provides several fixed‑data options for travelers to the Cayman Islands. For example, the Cayman Islands 20 GB 30 days plan gives 20 GB of high‑speed data valid for 30 days, and the Vodafone Travel (International) plan offers 25 GB for 30 days. These fixed plans can be more cost‑effective unless a user requires truly unlimited data usage.

eSimfly does not provide an eSIM for the Cayman Islands that includes a local phone number or SMS capability.
Only data‑only plans are available from this provider for that destination; you can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages.

eSimfly lists 12 single‑country data plans that include the Cayman Islands and 29 multi‑country plans that cover the Cayman Islands as part of larger regional packages. Prices for the available plans range from approximately $4.38 to $100.19, while data allowances span from 1 GB up to 25 GB over validity periods of 5 to 365 days. The catalog distinguishes between daily data cap options—there is one plan that refreshes a set amount of data each day—and fixed data cap options, comprising the majority of the offerings.
