ViaConecta does not offer a Hungary eSIM that includes a phone number or SMS capabilities. The provider provides only data‑only plans for travelers visiting Hungary.
Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the messaging and calling apps you rely on are accessible in Hungary before purchasing.
