Verizon 5C Works But No Sound Or Mic On Calls
I have an iPhone 5C that I replaced the screen on myself. Everything works great on the phone. Wifi works, proximity sensor, microphone, speakerphone, and earpiece speaker works. I tested them with the voice memo app and it all works great. No fuzzy sound, no issues there. Siri works and recognizes commands just fine. As far as I can tell, there's no issues.
Until, I activated it on Verizon, and when I make calls, no one can hear me, and I cannot hear them, nor can I hear the ringing or anything. It's not fuzzy or scratchy, just no sound. Even on speakerphone.
I had cut my sim card to fit into the iphone 5C so I thought maybe I messed up the sim card. Went to Verizon and got it replaced and still had no effect.
Everything else worked on the phone. Internet connectivity worked, texting worked, no issues with anything else.
What could be wrong?
