Using Data Traffic when Traveling
When you travel outside of your home cellphone network, you may need to access the
internet using cellular data traffic. If so, you need to activate data roaming on your device.
You may incur additional charges when you activate data roaming. It is recommended to
check the relevant data transmission charges in advance.
If you are using a device that has multiple users, you may need to log in as the owner (that is,
the primary user) to activate or deactivate data roaming.
