AeroSims eSIM Data Plans for Cayman Islands

AeroSims does not provide a true unlimited data eSIM for the Cayman Islands. The plans that carry the word “Unlimited” are capped at 1 GB per day; once that amount is reached the speed is throttled, but no further unlimited data is supplied.

Instead, AeroSims offers fixed‑data alternatives. For example, a 20GB plan for 30 days costs $112.19 USD, and a 10GB plan for the same period is priced at $61.12 USD. These fixed‑data options may be more cost‑effective for most travelers who need a reliable amount of high‑speed data without the daily cap imposed by the “Unlimited” plans.

AeroSims does not offer a Cayman Islands eSIM that includes a phone number or SMS capability. The only eSIM products sold by AeroSims for the Cayman Islands are data‑only plans.

Users who need voice or text calls can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict certain apps, so travelers should confirm that the applications they rely on are accessible in the Cayman Islands before purchasing a data‑only eSIM.

AeroSims lists 11 single‑country plans and 3 multi‑country plans that cover the Cayman Islands. The available options span a price range of roughly $9.61 to $228.86, data caps from 1 GB to 20 GB, and validity periods from 1 to 30 days. Among these, 6 plans feature a daily data cap that limits usage each day, while 8 plans use a fixed data cap that provides a set amount of data for the entire validity period.
