Turn mobile data on or off
From the Mobile network screen, select the Mobile Data switch.
Note: Mobile data is on by default. Turning off mobile data will not allow any data to be transferred over the wireless network. Wi-Fi access, voice function, and standard text messaging are still allowed. You can also turn data on or off by device using your own myAT&T account.

Turn international data on or off
From the Mobile network screen, select the International Data Roaming switch.Â
