eSimfly eSIM Data Plans for Cayman Islands

eSimfly does not provide truly unlimited high‑speed data eSIM plans for the Cayman Islands. The plans that carry the word “Unlimited” in their titles actually offer a fixed amount of high‑speed data—typically 1 GB for the entire validity period—after which speed would be throttled.

Instead, travelers can select from eSimfly’s fixed‑data plans. For example, a 20 GB plan valid for 30 days costs $117.28 USD, and a 10 GB plan for the same duration costs $69.68 USD. These plans cover the Cayman Islands and may be more economical for users who need substantial data usage.

eSimfly does not provide an eSIM for the Cayman Islands that includes a local phone number or SMS capability.
Only data‑only plans are available from this provider for that destination; you can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages.

eSimfly lists 13 single‑country data plans and 16 multi‑country plans that include the Cayman Islands. The available plans cover a price range from $7.69 to $221.94, data caps from 1 GB to 20 GB, and validity periods from one to 365 days. Among these options, six plans have a daily data‑cap feature while the remaining 23 are fixed data‑cap plans, and many allow tethering, giving travelers flexible choices depending on their usage needs.
