I have used a GB of data in less than 24 hours, how is this possible I got my android phone a week ago. This morning I recieved an text from telus telling me I have used 75% of my data, then an hour later I recieved a text saying I used 95%. Since I was sleeping and was not using my phone I want to know if this is at all possible, I took my phone into telus and all the settings for wifi are off. Is someone taking internet from me? What should my settings be?
All sorts of background processes and applications will use cell data bandwidth.  If you've installed some new apps recently, which given your phone is only a week old seems likely, check to see if some of them are doing anything in the background.

If you list your apps, perhaps we could shed some light on which ones might be data hogs.
