Stellar eSim does not offer any eSIM plan for Vatican City that includes a local phone number or SMS capability. Travelers who wish to use the electronic SIM for their trip will only have access to a data‑only connection.
For voice and messaging, users can rely on internet‑based services such as WhatsApp, Telegram, or iMessage over the data link. Because some destinations may block or restrict certain VoIP applications, it is recommended that travelers confirm that the specific apps they intend to use are accessible in Vatican City before making a purchase.
