Why do I sound like I'm in a tunnel when using the ZTE ZMAX

everyone i talk to on my new phone says i either echo or sound as if i'm in a tunnel. Not only that, when talking, only half of the conversation comes through. Its very intermittent. Very hard to hear and understand. I am with tmobile. What can I do? replace the phone?




Possibly a network issue. Also check if the mic piece is clean or if something is blocking it. Other than that, if all is ok, than it can be a hardware issue which you may need experts to look at.
