This is a petition for t mobile to release an app in the play store that allows unlocked independent cell phones to have Wi-Fi calling and text messaging!
I bought an unlocked Sony xperia z3 compact (because it's not offered by T-Mobile yet...) but found out that it cannot make Wi-Fi calls like my previous cheap-o LG phone did. This is a big problem because at my work I only get Wi-Fi signal and no T-Mobile signal.
The phone's operating system does allow for internet calling but it requires adding an "SIP account". T-Mobile support would not release the SIP settings when I called them.
I believe the Wi-Fi calling app was available in the past but was taken off... Wi-Fi calling is important for customers with unlocked independent phones!!!
