Hungary’s National Media & Infocommunications Authority (Nemzeti Media- es Hirkozlesi Hatosag, NMHH) confirmed on its website that the country’s three largest mobile operators, Magyar Telekom, Telenor and Vodafone, have been formally registered to compete in the upcoming auction procedure for frequency usage rights in the 900MHz and 1800MHz bands, expected to take place early next year. Fourth-placed mobile player DIGI Hungary is not participating in the process, but has launched a petition against the NMHH’s auction entry conditions.
