For any of the criteria added to the policy event, you can choose one of the following options:
Network Type (data service policies only): Select from 2G, 3G, 4G, Cellular Network (default, any 2G, 3G, or 4G), or WiFi
App Visibility (data service policies only): Select from Background (default, an app running but not visible on the device) or Foreground or Streaming (a visible running app or an app that's streaming, whether it's in the foreground or background).
Time of Day: Select Start and Stop times and days or select Weekdays or Weekends.
Devices synchronize their clocks and the time zone they are in with the nearest cell tower for policy enforcement, so attempts to adjust the device clock to get service outside of any times defined by policy will not be successful.
