AloOui eSIM Data Plans for Cayman Islands

AloOui does not provide a truly unlimited data eSIM for the Cayman Islands. The plans that carry “Unlimited” in their names actually give a fixed amount of high‑speed data each day—1GB or 2GB—and once that limit is reached the speed is reduced to 512 kbps or 1.25 Mbps. For travelers who need a larger or unrestricted data allowance, fixed‑data plans are available. Examples include the 50GB 30 days plan and the 20GB 30 days plan, both of which offer a set amount of high‑speed data that does not throttle until the data cap is reached.

AloOui does not provide a Cayman Islands eSIM that includes a local phone number or SMS capability. Travelers can only purchase data‑only eSIMs from AloOui for the Cayman Islands. However, over the data connection, common VoIP applications such as WhatsApp, Telegram and iMessage can be used for voice and messaging. Users should confirm that these services are accessible in the Cayman Islands before purchasing, as some destinations may block or restrict VoIP usage.

AloOui offers 25 single‑country data plans and 25 multi‑country data plans for the Cayman Islands, giving travelers 50 different options in total. The plans include both fixed data caps, of which 20 are available, and daily data‑cap plans, numbering 30. Prices for these options range from $14.82 to $416.20, and the data allowances span from 1 GB up to 50 GB, giving users a broad spectrum of choices that suit short stays or longer visits.
