We use Wi-Fi calling exclusively as there is no cellular signal at our home. Dialing numbers manually works great, but Siri doesn't recognize that we can make calls over Wi-Fi.
Telling Siri "Call John Doe"
Results in Siri Replying: "Calling John Doe... Oh uh, I can't seem to find a good connection. Please try your phone call again when you have better cellular service"
Please T-Mobile work with Apple to get this fixed! It's an Accessibility issue.
Good news guys it looks like Apple finally fixed this issue in iOS 10! Just tested with Airplane mode enabled and wifi calling and was able to make a call with Siri. Yay
