1. From the home screen, tap the Apps icon.
   
2. Swipe to then tap myAT&T to view and manage account settings.
   
3. Alternately, to check your current month's data usage dial *data# (*3282#) on your mobile phone to receive a text message with the current bill cycle's usage.
   
4. When the mobile data limit is active and has been reached, the mobile data block will remain in effect until mobile data is manually re-enabled on the device, the limit threshold is changed to a higher value, or a new data usage cycle begins. If you set data usage limits on your device, they do not communicate with AT&T systems. You will still receive AT&T system generated notifications as you approach your data limits.
   Note: To restrict apps from using data while running in the background, tap the Menu icon > Restrict background data.
