Astaroam eSIM Data Plans for Cayman Islands

Astaroam does not provide an unlimited data eSIM plan for the Cayman Islands. All available plans have a set data cap, ranging from 5GB to 20GB for a 30‑day validity period.

Travelers who require more data can choose from fixed‑data options, such as the 20GB 30‑day plan priced at $102.65 USD or the 10GB 30‑day plan costing $57.98 USD. These plans offer high‑speed 5G coverage in the Cayman Islands. Selecting a fixed data plan may be more economical for most users, unless the traveler expects to use an extremely large amount of data.

Astaroam does not provide a Cayman Islands eSIM that includes a local phone number or SMS capability. Only data‑only eSIMs are offered for this destination. Travelers can still use popular VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages.

Astaroam offers ten data plans that cover the Cayman Islands, split into six single‑country packages and four multi‑country options. The single‑country plans are tailored for use only in the Cayman Islands, while the multi‑country plans bundle the Cayman Islands with additional destinations, allowing customers to travel without needing separate subscriptions. Prices range from about $12.20 to $182.31, data allowances vary from 1 GB to 20 GB, and validity periods span 7 to 30 days. Some plans also allow tethering, letting users share data with other devices.
