I just bought the Samsung Note II. It was hard to get connected to the play store to download my aps, so I fiddled with some settings, turned my phone off and on again and then got connected. I am monitoring my "Nationwide" usage (not even sure what that is), and it is already at 138MB in one day (max is 400MB). I'm trying to figure out why it is so high. Is it because I had to download all my aps again? I've turned off WiFi and data, so not to get charged any more usage. Just wondering what I can turn on so my data doesn't keep getting used so much? Can I just use the WiFi, or does Data always need to be on? On my last phone, the LG Black, I always had WiFi scanning and Data was always on, but never noticed and increase in data usage. Any help would be great, thanks !
