Is anyone else having this problem? I just purchased the phone on 09/28/13. It worked great in the store and at home. Then I go to work in the downtown area and BAM no service. This has not happened before with my two previous phones and others in my workplace who are verizon customers but have different phones have 4G service. I have had the sim card replaced and I was also given another phone (in case I had a bad one). Still No Service and this is not good for me. Others are looking at my phone and are considering purchasing one until I tell them about the service issue. Also I was in another part of town and the same thing No service. What to do? I love this phone when it has service.
