For the last couple of weeks my data has dropped considerably. It's at 1x most of the time, but if I restart my phone it pops up to 4G. Sometime it will stay there for a while, but then drops ti 1x. I restart my phone and it's back up to 4G. It's a if the computer is kicking me out of the system so I can't use much of my "Unlimited Data." I'm no where near where it should slow me down.
