Hungary’s National Media & Infocommunications Authority (NMHH) has invoked the EU net neutrality framework rules once more, in a judgement against cellco Telenor Hungary. The regulator ruled that Telenor violated the EU net neutrality principles by distinguishing between specific content types, including its ‘MyChat’ instant messaging application and other social media apps, and between its ‘MyMusic’ service and online radio stations. The practices are disadvantageous to competing services, the watchdog stated in a decision which can be appealed by Telenor. CommsUpdate reported last month that the NMHH invoked the EU net neutrality framework rules to order Hungary’s largest fixed and mobile operator Magyar Telekom to cease ‘zero rating’ selected over-the-top (OTT) internet video services for its mobile users (i.e. giving subscribers access to the services without registering any data volume usage).
