    Is anyone running Windows 10 on the Lumia 640 with T-Mobile? Can you confirm whether wifi calling works?

    I'm not, but I recall seeing someone mention in another thread that it is not currently working.

    I know this news is disappointing. This is a temporary, not permanent, situation. Without going into great technical detail, I will summarize and say that if you are on a build greater than the one noted above and update to Windows 10 Technical Preview, your device would not be able to recover back to Windows Phone 8.1 if you were to encounter any device troubles or decide the Preview wasn't to your liking
