I just got my note couple of days ago, and I used a lot these days at home though wifi. I went out yesterday and turned on my data plan for just 15mins, it spent 32MB, I have no idea why. I just checked my email and replied one email during that 15mins,and the emails I read have no attachment,just text. Is there problem with my note? Even I have 1gb data a month, I don't think it's enough if like this way.
