Has anyone else noticed data usage at strange hours and/or while being on WiFi. After receiving a text last month stating I was almost over on my data I have tracked the data on my account. I have noticed data usage around 4-5 am when my wife and I are sleeping, and if we was awake we always use WiFi at home. Some days it is as small as .00001 gb and I even noticed a time or two it was almost a whole gb. It is also happening on my son's phone and he uses an Android phone so it is not just an Apple thing.
