is there an sip setting to use wifi calling for unlocked android devices?
i have xperia pro. i'm disappointed that the wifi calling app is gone and now, the feature is integrated to their carrier customization of their devices. i 'm thinking if is it possible to use that feature by setting up sip if they have one?
SIP has nothing to do with tmobile wi-fi calling.
T-mobile wi-fi calling can be ported for many Android devices.
I am using HTC HD2 and Samsung Infuse (at&T), and Sumnsung Galaxy 7 tab with t-mobile wi-fi calling.
you can search xda developers to get more information for "t-mobile wi-fi calling" flashable zip package .
