SimSmash eSIM Data Plans for Cayman Islands

SimSmash does not provide a truly unlimited data eSIM plan for the Cayman Islands. The plans that carry “Unlimited” in their names, such as Caribbean Daily Unlimited or Cayman Islands Daily Unlimited, actually include fixed data caps ranging from 490 MB to 10 GB for a single day, after which the speed would be reduced. Travelers who need more data can choose from the fixed data plans, for example the Cayman Islands 20 GB for 30 days plan priced at $97.99 USD or the Cayman Islands 10 GB for 30 days plan priced at $52.99 USD. These fixed‑data options offer a larger amount of high‑speed data and may be more cost‑effective for long‑term usage in the Cayman Islands.

SimSmash does not provide an eSIM with a phone number or SMS capability for the Cayman Islands. The only plans offered by SimSmash for Cayman Islands are data‑only eSIMs, so travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage to make calls and send messages over the data connection.

SimSmash offers a total of 16 data plans for the Cayman Islands, split between single‑country and multi‑country options. There are nine single‑country plans specifically tailored for use within the Cayman Islands, and seven multi‑country plans that include the Cayman Islands as part of a broader regional package. Prices for these plans range from about $3.99 to $97.99, with data allowances between 490 MB and 20 GB and validity periods from one to 30 days; many of the plans also support tethering. The single‑country offerings tend to come in fixed data amounts per day, while the multi‑country plans often provide a bundled data cap that can be used across several destinations.
