My wife and I just activated our phones this past monday. We opted for the 200mb data plan to see how it went. I've been 100% on wifi this week as I haven't left the house but once and never used data while I was gone and I'm at 7mb used. My wife says she's downloaded about 30aps mixed wifi and 3g, sent and received 5 emails, not streamed any media (netflix/pandora etc). She is about 360mb used.... She got home today at 5:30pm and I checked her usage. She was at 78mb at 5:30pm. We went across the street to our friends house for dinner at 7:45 when she got a text saying she was over her 200mb limit. I checked her usage and it showed 360mb used. My question: Where did this data come from in the first place and why did we not get a text until she was over the limit and near halfway into the second allotment?
