Voyasim does not currently offer an eSIM plan for Vatican City that includes a phone number or SMS capability. The provider only offers data‑only eSIM plans for this destination, without inbound or outbound voice or text services.
If travelers need to make calls or send messages, VoIP services such as WhatsApp, Telegram, and iMessage can typically be used over the data connection that the eSIM provides. However, some destinations may block or restrict access to specific apps or VoIP services, so users should verify that the apps they rely on are accessible in Vatican City before purchasing an eSIM.
