Controlling data usage
You can keep track of the amount of data transferred to and from your device over your
mobile data or Wi-Fi® 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.
