Bill has a family plan with Verizon and one of his kids has been using up most of the data resulting in three overage charges. The problem is, he doesn't use it much. Leo says he'll need to look at the phone and see what it says. He should look at the cell usage in the settings. If it roughly matches, then there's something that the iPhone is doing that is burning up bandwidth. The good news is that he can look at the data usage by app in the iPhone's settings.
Gene is getting huge bills from Sprint with overage charges. He thought he was supposed to have unlimited data. Leo says that Gene should call Sprint and see if there's been a billing error. It may also be that Gene has malware on his phone that is causing overages by using the data.
