AeroSims eSIM Data Plans for Cayman Islands

AeroSims does not offer a truly unlimited high‑speed data eSIM for the Cayman Islands. The plans that carry the “Unlimited” name actually provide a hard cap of 2GB of high‑speed data per day; after the limit is reached the data speed is reduced to 512kbps.

AeroSims provides fixed‑data options instead, such as a 20GB plan valid for 30 days or a 10GB plan also valid for 30 days. These plans give a set amount of high‑speed data that must be used within the validity period and do not include unlimited data or speed caps. Adding more data after the initial amount can be done through the eSIM’s top‑up feature, but the remaining capacity remains fixed until the validity expires.

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 provides 11 single‑country data plans and 3 multi‑country data plans that include the Cayman Islands. The single‑country options give a fixed amount of data that is used throughout the validity period, while the multi‑country plans allow the user to switch between several destinations—though each plan still offers a fixed data cap. Across all AeroSims plans for the Cayman Islands the price ranges roughly from $14.77 to $400.00, and the data caps vary between 2 GB and 20 GB.
