I recently purchased a Samsung Focus from AT&T, along with that I have the 200Mb per month data plan. My Windows Phone seems to be using quite a bit of data... Yesterday I went on Facebook three times on 3G other than that I was on Wifi and had data turned off, and some how my data accumulation was 10MB for just that day. Back when i had my iPhone I had trouble getting 5MB a day but 10MB? Weather Bug is the ONLY live tile that I have and i have that set to update every 4 hours, feedback is turned off, phone updates are turned off, the connect with Zune feature is turned off, the only thing I could think of is last night when I was watching a movie on Netflix via Wifi I forgot to turn my data connection off other than that I did no streaming of any sort. I know my way around this phone pretty well, Ive read other forums on saving data. Could that really have used that much data or is there something else causing so much data to be used? Any answers on ways to conserve data would be very much appreciated. Thanks.
