Recently my area shows 3g where ever I go. I uses to only get 4g. I turn off 4g (global mode) and enable CDMA only to save battery. So I was thinking this would be a perfect way to use data when 4g is off. I updated my phone with the update towers feature to be sure but I still can not use data. It shows 3g with 4 bars and the up and down arrows indicate data transfer but I never can pull up a web page. Is this not going to work?
