eSIM.sm eSIM Data Plans for Cayman Islands

eSIM.sm does not provide an unlimited data eSIM for the Cayman Islands. All available plans for this destination feature a fixed data cap. For example, the 10GB 30 days plan costs $77.80 USD, and the 5GB 15 days plan costs $41.10 USD. These fixed‑data options may be more cost effective for travelers who consume large amounts of data, while those who need truly unlimited data would need to look beyond eSIM.sm.

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 currently provides five multi‑country data plans for the Cayman Islands. The plans span a price range of roughly $10.70 to $77.80 and offer data caps between 1 GB and 10 GB, with validity periods of 7 to 30 days. Tethering is supported on some plans, and no single‑country plans are available.
