YeeSiM eSIM Data Plans for Cayman Islands

YeeSiM does not currently offer any unlimited data eSIM plans for the Cayman Islands; all available plans have a capped data allowance.

The provider does sell fixed data plans. For example, a 10GB plan is valid for 30 days and priced at $102.00 USD, while a 5GB plan is also valid for 30 days at $61.00 USD. These examples are hand‑picked to illustrate the larger data options and represent only a subset of the available plans, not the full list. Choosing a fixed data plan can be more cost‑effective for most travelers, unless you anticipate extremely heavy data usage.

YeeSiM does not provide Cayman Islands eSIMs that include a local phone number or SMS capability. The available eSIM plans from this provider are data‑only, allowing internet access but not traditional voice or text messaging. Travelers can still use video and messaging apps such as WhatsApp, Telegram, or iMessage over the data connection to communicate without a local phone number.

YeeSiM offers three multi country plans for the Cayman Islands. The plans cover 1 GB to 10 GB of data, are valid for 7 to 30 days, and range in price from $14 to $102. No single country plans are available. All of the multi country options allow tethering.
