EE to begin trialing calls over Wi-Fi in the UK, 4G support coming in 2015

UK mobile operator EE has today announced trials for calls to be held over Wi-Fi will commence later this year. The trial is part of a £275 million investment in advanced voice capabilities, helping connect more rural parts of the UK who don't have the strongest levels of signal with EE. Launching the trial later this year, EE has also upgraded both 2G and 3G sites to handle the increased data usage across the network and make way for 4G calling services to launch in 2015.
