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.
