Advanced data usage settings
Two other settings available from the Menu icon can have dra-
matic effects—but may sometimes be useful:
• Data roaming can result in steep additional charges. However,
in some locations this may be the only way to connect to the
Internet.
• Restrict background data affects all your apps across all avail-
able networks, and may cause some features to stop working.
This is an extreme step that should be used with caution.
Control airplane mode & other network
settings
With the exception of VPN, which is visible only to a tablet’s own-
er, any user can adjust these global settings.
These settings are available under Settings > Wireless & net-
works > More.
• Airplane mode. Check to turn off all data transmission from
the tablet.
• VPN. Touch to adjust settings for accessing a secured local
network from outside that network. See “Connect to virtual
private networks” in next section. (Available only for Nexus 7
with mobile data.)
• NFC. Check to turn on Near Field Communication (NFC) fea-
ture (required for Android Beam).
