Hi3G Access Denmark (3) has launched voice-over-LTE (VoLTE) technology over its network, nearly one year after it commercially introduced its voice-over-Wi-Fi (VoWiFi) services in April 2016. The operator revealed the new service – included with its Fri-Tale subscriptions – will provide customers with better sound quality and shorter connection times. In parallel, 3 has extended the VoWiFi service to users utilising a number of Sony Xperia and Samsung handsets.
