Having only introduced the service in May, 3UK revealed that around 15,000 of its subscribers are already making HD Voice calls every day.
The company, which followed Orange with the adoption of the technology, claims that improved voice quality has proved popular with customers,although the free service only works between 3UK customers right now.
"HD Voice really does take voice calling to the next level," Marc Allera, 3UK's sales and marketing director, told Mobile Today. "This is the most significant development in voice technology to hit the UK mobile market in more than 20 years...and, as well as crystal clear voice calls, HD Voice helps reduce background noise and should make shouting down the phone a thing of the past."
Meanwhile, France Telecom Orange already has over 1 million HD Voice users across all of its networks, together with 800,000 users on its fixed infrastructure, and has announced ambitious expansion plans. FT Orange plans to expand HD Voice service from 10 countries to 16, with more handsets supporting the technology being added to the 20 already enabled with HD Voice.
Of particular note, FT Orange has committed to make HD Voice interoperable between its networks in different countries sometime between 2012 and 1013, and then provide this capability between selected operators using the AMR-WB codec standard. SFR, Telekom Austria, Telecom Italia and T-Mobile are thought to be close to announcing plans to adopt HD Voice technology over the next few months.
