Hie all of Iphone users or iphone expert.. I would like to ask why my iphone automatically spend my credits even though i never call and sms ?? I bought the iphone from my friend directly. I'm using prepaid right now...

One of my friend said that For sure is internet application "ON" which i unable to close up all of the application. An example Store application. I would going to apply postpaid soon but before this, I just want to make sure what's my problem ?? I'm a worry that i apply for postpaid and become more quickly spending credits. It might be cost me a hundred amount !!! Thank you..
