I am new to smartphones so please excuse the noob questions. I got my phone on Sunday and both my kids loved them so much I got them both them on Friday. We have not left the house since Friday and both kids immediately turned on wireless when we got them. They of course have been on them non stop. My son is showing that he has used 0 of his data but my daughters is showing 93 MB. Like I said she is using it wirelessly only since we haven't left the house. Her signal strength is very strong as we have a really good router and I have told them to keep an eye on the wireless signal and make sure it is strong whenever they are using it. Does anyone have any idea why it would be using data? I called AT&T and the women I spoke with had no idea and told me someone would call me back in 24-48 hours. Thanks for any suggestions you can give.
