  6. TURN ON/OFF INTERNATIONAL DATA ROAMING: From the Data usage screen, select International Data Roaming.
    Note: Data roaming is off by default. Enabling Data roaming will allow the device to attach to foreign wireless network signals when available. International roaming charges will apply. This setting does not apply to voice access, which requires additional provisioning for usage on international networks. To learn more, visit the AT&T International website.
