I got my mother a phone so that she could join the new century and get rid of the house phone.She uses it for calling, texting, and facebook. I didn't put a data plan on the phone because she wouldn't have known what to do with it anyway. Well, I received the bill and I owe for data. This was surprising because I had set the data usage to OFF. It has never been ON ever. I really don't want to pay for the data charges. Please help.
