Why do I keep having problems with voice on my iPhone Plus?
since I got my iPhone in Nov 2014, I've had problems hearing when I'm on the phone and ppl I'm talking to have problems hearing me as well. I have gone to Apple twice and was given a new iPhone along with a new chip and I'm still having the same problem. There are 4 iPhones on our AT&T account (2 iPhone 6 and 2 iPhones 6 Plus and we are all having the same problem. Apple tells me it's a carrier problem. AT&T disagrees.
