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.
Adjusting data usage settings can help you keep greater control over data usage but cannot
guarantee the prevention of additional charges.
