VoidMob does not provide an eSIM plan for the Cayman Islands that includes a phone number or SMS capability. Travelers who purchase a VoidMob eSIM for the Cayman Islands will receive only a data‑only connection; the plan will not grant inbound or outbound voice or text messaging service.
If calls or messages are needed, users can rely on data‑based VoIP services such as WhatsApp, Telegram and iMessage, which typically function over the data link. These services may be subject to local restrictions, so travelers should confirm that the apps they plan to use are accessible in the Cayman Islands before buying a VoidMob data-only eSIM.
