Horrible call quality since network setting were updated about a week ago

[DavStaa]

My call quality (includes all lines on my plan) has been horrible ever since received a carrier settings update about a week or so ago.  Is anybody else having this issue?

I took the carrier update on 12/21 and didn't run into any challenges. If that the carrier update your referring to? e.g. Verizon 23.2? Just curious. Settings > General > About > Carrier version is listed.

I want nothing but the best calling quality for you David. Let’s get more info on this issue, and explore ways to improve your wireless experience. What is your phone model? Do you experience this service issue in a particular place only (home, school, office)? What is your ZIP code? Have you called tech support at 800-922-0204 to troubleshoot? If you have, please share the steps that you have taken so that I don’t ask you to do the same things.

The last carrier update I noticed turned off LTE calling for a short while on the devices. It appears to just be a bug. Try this if you use an iPhone 6/6+ or newer:

Go to Settings > Cellular > Use LTE. Allow this menu option to load for a few seconds, and then set it to Voice and Data.

If the above setting was set to off or data only, your call is being placed over the legacy CDMA network, which sounds much worse
