I figured I would give WiFi calling a try on T-Mobile, so I turned it on. As soon as I did, I got a message that turning WiFi calling on means that handoff of voice calls will be unavailable to all my other devices. Bummer, I think, but if I want it back I can probably just turn Wifi calling off and get it back, right? Well... This after I turned WiFi calling off, and turned hand off off and then back on. Even after rebooting the phone and iPad, still no go. So have I just wrecked handoff forever, or is there some way to get this back? Never would've even tried Wifi calling if I had known this was gonna happen.
