Vodafone UK is looking towards the future of voice calls by rolling out Wi-Fi Calling on the Galaxy S6 and the Galaxy S6 Edge this autumn. After updating these devices, you'll find an ability to call someone over a Wi-Fi network, and according to Vodafone UK, this feature works on many remote locations such as the London Underground or older buildings with thick walls, or even basements. What's more is that Vodafone UK has recently rolled out 4G+ and HD Voice, both of which will greatly enhance the quality of calls performed through a Wi-Fi network.
Currently, Vodafone UK only supports Apple's iPhone 6s and iPhone 6s Plus devices, but they are also adding Samsung's latest flagship to the list, and you need a Pay monthly Red or Red Value Bundle, Red+ or Business Premier. You don't have to install any apps whatsoever, because the Galaxy S6 and Galaxy S6 Edge come with this feature out of the box, so after updating them you'll simply have to connect to a Wi-Fi network and then turn on Wi-Fi Calling in the settings menu.
