Yesim eSIM Data Plans for Cayman Islands

Yesim offers unlimited data eSIM plans for the Cayman Islands. The available unlimited plans range in price from $17.45 USD for a 1‑day validity up to $115.17 USD for a 30‑day validity. All of these plans allow tethering and specify that normal speeds may be throttled after heavy usage under a Fair Usage Policy. Travelers interested in speed restrictions should contact Yesim to confirm the typical amount of data that remains at normal speed before throttling applies.

Yesim does not provide a Cayman Islands eSIM that includes a phone number or SMS capability. The available eSIM plans from this provider are data‑only and do not support inbound or outbound voice calls or SMS. Travelers who need to communicate while in the Cayman Islands can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, though some destinations might restrict or block access to certain apps, so it is advisable to verify that the services you rely on are available in the Cayman Islands before purchasing an eSIM.

Yesim offers two categories of data plans for travelers to the Cayman Islands: single‑country plans and multi‑country plans. The single‑country catalogue contains eight options, while the multi‑country selection includes twelve plans that cover the Cayman Islands alongside other destinations. Across these offerings, the price spectrum ranges from about $7.60 to $145.45, with data sizes spanning from 1 GB up to unlimited data, and validity periods that can be as short as one day or extend to an entire year. Some plans also allow tethering, although speed may be throttled under certain conditions.
