Well, never got around to upgrading like I had said all those months ago, but the latest Windows 10 Mobile preview has me intrigued again. So the question as before, anyone try this latest preview on their Tmo 635? Wifi calling still working good?
Just saw this old thread. I've been using Windows 10 Mobile Insider's Preview for months and have had Wi-Fi calling work maybe once in that whole time. Other people have said it works for them but I haven't been able to make it happen.
