Yesim eSIM Data Plans for Cayman Islands

Yesim offers unlimited data eSIM plans for the Cayman Islands with validity options of 1 day, 7 days, 15 days, and 30 days. Prices vary from $17.40 for the 1‑day plan to $114.86 for the 30‑day plan. All unlimited plans include tethering, use of 3G and LTE networks, and come with a note that speeds may be throttled after heavy usage.

Because the plans are marked as unlimited but include a Fair Usage Policy, travelers may experience reduced speeds after consuming a large amount of data. If you are concerned about potential speed restrictions, please contact Yesim directly to confirm the exact allowance at normal speed and any applicable limits.

Yesim does not provide eSIM plans for the Cayman Islands that include a phone number or SMS capability. All available Cayman Islands eSIMs from Yesim are data‑only. Travelers who need voice or text communication can use popular VoIP apps such as WhatsApp, Telegram, and iMessage, which work over the data connection and do not require a local phone number or SMS service.

Yesim offers a total of 17 different data plans for the Cayman Islands. This total comprises 7 single‑country plans that provide coverage only within the Cayman Islands, and 10 multi‑country plans that include the Cayman Islands alongside other destinations. The plans range in price from about $17.40 to $126.46 and in data from 3 GB up to unlimited. Some plans are sold as fixed data packages while others may operate on a daily data cap, giving travelers flexibility depending on their usage needs.
