Bordersim does not offer Cayman Islands eSIM plans that provide a local phone number or SMS capability. The Cayman Islands plans available from Bordersim are strictly data‑only.
Travelers looking to make calls or send messages can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict these services, so it is advisable to verify that the apps you intend to use are accessible in Cayman Islands before purchasing a plan.
