How do you tell when and why you're using data? Admittedly I'm a smart phone newbie here. I just got the Samsung Note II a few hours ago but I have some technological smarts. I for sure haven't checked email or been on the internet - all I've done is set up my voice mail. Yet apparently I've already used 25 MB of my data. How? Is it getting eaten my some background function like reporting the weather on the home screen?
