I'm on Verizon right now and I am thinking about switching to At&t I have a Motorola razor max and before that I had the iPhone4s and it's kinda slow usually only have 1 or 2 bars rarely do I get more bars of signal and when I'm in a shopping store like publix or target I drop calls I know I can compare coverage between Verizon and At&t but which one gets better reception in general?
