EE, Vodafone and Three take different approaches to Wi-Fi calling in the UK

All of the Tier 1 U.S. carriers have embraced Wi-Fi calling to varying degrees, with T-Mobile US (NYSE:TMUS) and Sprint (NYSE: S) more enthusiastic than AT&T Mobility (NYSE: T) and Verizon (NYSE: VZ) in deploying the technology. There are several ways operators have tried to launch Voice over Wi-Fi services in Europe. The first largely includes responses to Skype with peer-to-peer calling and messaging services, such as Orange's Libon service. The second includes downloadable applications such as Three's InTouch.
