Hello chaddaws! I understand your concern regarding the data usage that occurred when you may not have been using your phone. I would be concerned as well if I received data alerts. Data can occur in the background where it is possible to be used without you using the phone. Updates to applications can update automatically as well. We have several tools to monitor your data and can see how the data has been used. To learn more visit http://vz.to/2c9U2L6. We can assist with checking the settings on your phone, what make and model do you have?
