There are three mobile phone providers in Hungary. Mobile phone numbers have 11 digits, always prefixed with 06 30 (T-Mobile), 06 60 (T-Mobile) or 06 20 (Pannon) and 06 70 (Vodafone). To make calls between two mobiles on the same network, drop these first four digits; to make calls between two mobiles on different networks, drop only the 06. To call a mobile from a public or private phone, dial the entire 11-digit number.
