Access Point Names (APNs)
An APN is used to establish data connections between your device and the Internet.
The APN defines which type of IP address to use, which security methods to invoke,
and which fixed-end connections to use. Checking the APN is useful when you
cannot access the Internet, have no data connection, or cannot send or receive
multimedia messages.
If you are using a device with multiple users, only the owner, that is, the primary user, can set
or check APNs, but the settings made by the owner affect all other users.

If you have several available connections, the active network connection is indicated by a
marked button.

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.
To access data usage settings
1 From your Home screen, tap
2 Find and tap Settings > Data usage.
