eSIM.sm eSIM Data Plans for Cayman Islands

eSIM.sm does not provide an unlimited‑data eSIM for the Cayman Islands; all available plans have defined data caps. The catalog lists a 10GB plan for 30 days, a 5GB plan for 15 days, a 3GB plan for 10 days, a 3GB plan for 15 days, and a 1GB plan for 7 days, each with specified validity periods and prices.

For travelers who need more data than the fixed plans offer, eSIM.sm’s alternative is to choose a larger fixed‑data package—such as the 10GB 30‑day option—and use it as a budget‑friendly way to handle most data needs. This can be more cost‑effective for moderate usage compared to paying for additional data on the go, especially when you are not a very heavy data consumer.

eSIM.sm does not offer Cayman Islands eSIM plans that include a phone number and SMS. All Cayman Islands eSIM offerings from eSIM.sm are data‑only and lack inbound or outbound voice and SMS capability. Travelers who need to communicate can still use VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging.

eSIM.sm lists five multi‑country data plans for the Cayman Islands, with prices ranging from about $10.40 to $75.30 USD. The data caps available span from 1 GB up to 10 GB, and each plan lasts between 7 and 30 days. All of the plans support tethering.
