Why is my phone not picking up local service? I have a basic phone that was working great. However today it just started sporadically saying entering and leaving service area and jumping between no bars and many bars without me moving. I am definitely in an area where there should be service. When I try to call anything when I have bars it immediately goes to zero bars. I am also frequently getting a a message that says "CDMA service not available." I tried going to the verizon store but the rep was very unhelpful and said I would just need to call the tech support. Is there anything I can do for this problem?
