• SET BILLING CYCLE START: Select Start billing cycle on.

• ENABLE/DISABLE DATA LIMIT: Select the Set data limit switch.
• SET DATA LIMIT: When the Data limit switch is enabled, select 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.
