FullBars does not provide an eSIM for Vatican City that includes a local phone number or SMS capability. The only plans available from this provider for Vatican City are data‑only plans, so travelers will not receive an inbound or outbound voice or text service through the eSIM.
Travelers who still need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, but some destinations may block or restrict access to specific apps or VoIP services. It is recommended to verify that the applications you rely on are accessible in Vatican City before purchasing a data‑only eSIM from FullBars.
