    Had tons of problems with this on windows phone 8.0. Finally got the official t-mobile windows phone 8.1 update and now WiFi calling works great. Much more reliable than before, and so far no problems.

    Work good. Only thing you need is login your Tmobile account. Go to profile. Go to edit then enter your mailing address. That's all.

    Thanks for fixing the wifi calling feature in latest wp8.1 update. Works fine now, both SMS and call. However, voicemail does not sync. Have to disconnect and use regular cell network to sync visual voice mail. And of course would be nice to have seamless handover to LTE like iPhone 5s and 6 has.

    Update: Working again perfectly now!!!! Very happy 😊. Both phone calling and texting are working. Awesome 🙆 Was working fine with 8.1 and all the preview updates. But with the Aug 20 update, it only keeps saying error to connect to wifi. Terrible!!! Need to be fixed asap
