I have an Iphone X, which I got new in December 2018. I have been having intermittent issues with people saying they can not hear me clearly. I hear them fine.
I have been to Verizon twice where they did some updates. Then to the apple store twice, they did a reset and was finally given a replacement phone. I am STILL having the same issue. I never had this problem on my old Iphone 5C. Anyone else with a similar issue? Should I go back to Verizon? Back to Apple? The only thing that has not been done is a new SIM card.. Could this be the problem? I am at a loss and frustrated with this. Looking for any advice!!
