we have a nationwide share plan( my wife and I , seniors, ) which has unlimited data although she does not have a smart phone and does not use data....I wanted to switch my older 3g android galaxy S to at least a GalaxyS4.....but in order to do this I lose unlimited data...my plan goes up 30 or 40 bucks a month....and although I have been a Verizon customer forever..it seems that the only way I can get a 4G phone with some data is to switch carriers???
