It's been asked a billion times, but as of today - April 11, 2014 - is there ANY way - even with an app that I have to BUY/PURCHASE, that I can get WiFi calling to work on a non touchwiz based ROM?
There has always been APPS available to do so. Google Voice, and any VOIP provider. But they don't work with your original number. There is still currently no way to be able to use T-Mobile's WiFi Calling on any CM/AOSP ROM. It must really be a difficult thing to achieve.
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
