INSTRUCTIONS & INFO
From the home screen, swipe to, then tap AT&T. Note: 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.
Tap Usage Manager.
The DATA tab will provide data usage information.
Tap the Set mobile data limit checkbox to set a mobile data limit. Note: 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.
Touch, then drag the bar to set the desired Warning, and Data limits.
