iRoamly eSIM Data Plans for Cayman Islands

iRoamly does not offer a genuinely unlimited eSIM plan for the Cayman Islands. The plans listed are marked as “Unlimited” but actually provide a 500GB data allowance. Once that limit is reached, the connection is throttled to 5120kbps. The validity of these plans ranges from 1 day to 30 days, with pricing between $18.50 USD and $534.00 USD.

For travelers who prefer a strictly capped data allowance, iRoamly offers fixed data eSIM plans in addition to the “Unlimited” options. While the dataset does not list their specific quantities, these alternatives work on the same Cayman Islands network and avoid the post‑limit throttling that applies to the 500GB plans. This can be a more cost‑effective choice for heavy users who want a predictable data budget.

iRoamly does not currently offer any Cayman Islands plans that include a phone number or SMS capability. All iRoamly eSIM offerings for the Cayman Islands are data‑only, meaning the device will not receive a local phone number for inbound or outbound calls or text messages.

Travelers can still use popular VoIP applications such as WhatsApp, Telegram, or iMessage to make calls and send messages over the data connection provided by the eSIM. These apps do not require a local phone number or SMS service to function.

iRoamly provides 75 single‑country plans and 28 multi‑country plans that are valid for the Cayman Islands. The catalog includes both fixed‑data plans, where a set amount of data (from 500 MB up to 500 GB) is allocated for the validity period, and daily‑data‑cap plans, where the data allowance resets each day within the chosen validity window. Prices on the platform range from free to about $534 USD, reflecting the different data volumes and durations offered.
