Voyasim does not provide eSIM plans for Hungary that include a phone number or SMS capability; only data‑only plans are available from this provider. Travelers who need a local number would need to look for another service that offers voice and messaging.
Using the data‑only eSIM, popular VoIP applications such as WhatsApp, Telegram and iMessage can typically be used for calls and texts over the data connection. However, certain destinations can restrict or block specific VoIP services, so users should confirm that the apps they rely on are accessible in Hungary before purchasing an eSIM.
