JamboSim eSIM Data Plans for Cayman Islands

JamboSim does not provide a true unlimited data eSIM for the Cayman Islands. The only plan marketed as “Unlimited” gives 3 GB of high‑speed data per day and, once that amount is used, the speed drops to 1000 kbps. The plan lasts 7 days and is priced at $60.99 USD.

Travelers who need large amounts of high‑speed data can instead choose a fixed‑data option. For example, JamboSim offers a 20 GB plan valid for 30 days (priced at $38.99 USD) and a 10 GB plan valid for 30 days (priced at $23.99 USD). These plans provide the specified amount of data at full speed until the cap is reached, after which no data is available unless further renewal is purchased. This can be a more cost‑effective choice unless a visitor requires continuous high‑speed data usage.

JamboSim does not provide Cayman Islands eSIM plans that include a phone number or SMS capability. All Cayman Islands eSIMs sold by JamboSim are data‑only, so travelers can use Wi‑Fi or cellular data for web access, and can still communicate via VoIP applications such as WhatsApp, Telegram, or iMessage, which work over the data connection.

JamboSim makes six single‑country data plans and twenty‑four multi‑country plans available that cover the Cayman Islands. Most of the options are fixed‑data offerings; one plan features a daily data cap. Prices generally fall between roughly $2 and $108, and data caps vary from 200 MB to 20 GB.
