Germany’s national telecoms regulator, the Federal Network Agency (BNetzA), has banned aspects of Deutsche Telekom’s zero-rated music and video streaming service StreamOn and called on the company to implement changes to align StreamOn with EU requirements on net neutrality and roaming, according Telecompaper. Telekom has until the end of March 2018 to implement these changes or risk facing fines, said the agency.
Currently, data consumed with StreamOn is not deducted from the customer’s inclusive data volume if audio or video services from StreamOn’s content partners are used. This violates the net neutrality principle of the equal treatment of data, said the regulator. The agency also called for Telekom to offer StreamOn to customers throughout the EU under the EU’s ‘Roam like at Home’ principle. Under this principle, the data volume customers consume through StreamOn in other EU countries can no longer be deducted from the data volume included in their tariff, they said.
The agency said Telekom must also offer customers unrestricted bandwidth in all of its MagentaMobil tariffs. Currently, data transmission rates for video-streaming in the StreamOn MagentaMobil L Tariff are reduced so that customers can only stream videos in SD quality. But the agency said it found no "objective technical reason" for this reduction in transmission rates.
During the agency’s investigation, Telekom presented an amended version of its terms and conditions (AGBs) for content partners to go into effect 01 March 2018. These amended terms would allow private persons and streaming providers that offer a download function to become StreamOn partners and thus fulfill the Federal Network Agency’s requirements for an "open and discrimination-free participation" for StreamOn, it said.
The Federal Network Agency found in October that Telekom’s StreamOn service violated several principles of net neutrality. Still, the agency declined to ban the zero-rated data tariff entirely back then and instead called on Telekom to introduce changes to StreamOn to align it with net neutrality guidelines. 
Telekom to file objection
Telekom said it remains convinced that its StreamOn tariffs do not violate EU law and said it would file an objection to "legally clarify" the issue. Telekom criticized the Federal Network Agency’s decision as being "absolutely incomprehensible" and warned that the agency’s demands — like making StreamOn available in all EU countries — would ultimately mean that Telekom would no longer be able to afford to offer StreamOn free.
Because StreamOn is a free supplementary contract in Germany, the tariff does not need to be offered throughout the EU under its roaming guidelines, said Telekom. Transmitting data in SD-quality is likewise "absolutely sufficient" for mobile devices at the moment, said Telekom. 
Deutsche Telekom said it will assess how it will proceed with the agency’s order and noted that nothing would change at first for its StreamOn partners and customers as a result of the decision.
