On March 12, E-Plus announced it is delivering HD voice on its network.
The announcement via the company’s plug, held little information beyond the usual “Both parties must be on network, both parties must have HD voice capable devices to get HD voice” instructions along with a throwaway line that the Apple iPhone 5 supports HD voice.
E-Plus is the third-largest mobile operator in Germany with over 25 million subscribers. Perhaps appropriately, it is also the third operator to offer HD voice in Germany. Deutsche Telekom launched HD voice service in 2011, followed by Vodafone in 2013.
No discussion of if or when E-Plus will be able to start exchanging HD voice calls with other networks.
