eSIMsData does not provide any Cayman Islands eSIM that includes a phone number or SMS capability. All plans for this destination are data‑only, so travelers will only receive a data allowance with no voice or text messaging service from the provider.
Without a dedicated phone number, users can still stay connected by using VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, it is advisable to confirm that these services are accessible and not restricted in the Cayman Islands before purchasing a plan.
