A few months ago I was getting about 3 bars. Now I get no bars. I have never been able to answer a phone call it rings but no one can hear me and I can't hear them. I can't send a massage unless I am standing at the window and get 1 bar. I have a phone that is 3 months old and I am very disappointed in the service I get from it. I never get a 4g. I have a LG Zone3, my zip code 71646. please help me this phone and service is worthless to me!
