Controlling Data Usage - Sony Xperia Tablet Z SGP321 User Manual

Controlling data usage

You can keep track of the amount of data transferred to and from your device over
your mobile data or WLAN connection during a given period. For example, you can
view the amount of data used by individual applications. For data transferred over
your mobile data connection, you can also set data usage warnings and limits to
avoid additional charges.
If you are using a device with multiple users, only the owner, that is, the primary user, can
adjust data usage settings. Adjusting data usage settings can help you keep greater control
over data usage but cannot guarantee the prevention of additional charges.
