Sprint to launch HD Voice by the end of the year

Updated 4 years ago

Sprint (S) is planning to launch its HD Voice service for the HTC EVO 4G LTE by the end of the year, according to PhoneScoop. The feature, which was demonstrated at the company’s EVO 4G LTE launch event this past April, dramatically improves call quality but it requires both handsets support the service in order to be used. To ensure the quality of HD Voice, Sprint will need to upgrade a “critical mass” of its markets with various network improvements and launch additional smartphones that are compatible with the new feature. HD Voice will initially launch in select markets in 2012 and won’t become widely available until 2013 and 2014.
