I upgraded from the iPhone 4 to the 5s 4 months ago. Ever since I upgraded, I have periodic issues with call quality. In the middle of a call I will all the sidden start to hear myself talk and the person on the other end cant hear me at all and I cant hear them. This happens to be in the Atlanta, GA area in the same places on interstate 75.
That is unusual and is definetly worth looking into. Let's get you some help. What zip zode is that? Was the echoing happening on the iPhone 4? Are you using a bluetooth device?

The zip code is 770 and there may also be some 404 in the area. Both lines on my account experience this issue. This did not happen with our 4 & 4s. One of the lines uses a Bluetooth and the other does not.
Thank you so much for reaching back out to us. Could you please provide us with your mailing zip code? With your iPhone 5s can you please reset your network settings. You can do this by going into Settings, General, Reset, Reset Network Settings. Then re-try the call quality after that reset has been completed. Please keep us posted.
