Watching TV on a Mobile Network - Managing Data Usage
Watching TV and downloading content with the TV App on a mobile network uses your mobile data. Standard data usage charges may apply.
Watching HD programming with the TV app uses approximately 1 GB per hour. SD content uses approximately 0.5 GB per hour. You can limit how much data the application uses or disable playback and disable downloads over mobile networks altogether from the Video Quality tab in the settings. You can quickly check your data usage in the My Usage section of the My Account app.
