Ever since 9.3 betas and on to the release version I've had horrible WiFi Calling (att) and FaceTime audio signal quality. I used to use an MCELL in my apartment. Then went full WiFi Calling with iOS 9 and it's been great. But Since 9.3 I've had to go back to MCELL because no-one can hear me clearly with WiFi Calling or even FaceTime Audio. Pretty bummed about this. Anyone else?
