Â
3. Select the desired SIM.
Â
Â
Â
From the desired SIM's screen, select SIM preferences, then 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.
Â
From the desired SIM's screen, select the International Data Roaming switch.Â
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.
