3. Drag the red line by its right side to the 
limit you want to set.
When your data usage reaches the limit, 
mobile data will be turned off automati­
cally and many features of your phone 
won’t work correctly. You’ll receive a no ­
tification when this occurs.
View or restrict data usage by app
Some apps transfer data in the background—
that is, when you’re not actually using the 
app, it may download data for future refer ­
ence. Restricting background data usage for 
individual apps can sometimes be a useful 
way to reduce your overall data usage. How ­
ever, this is a drastic measure that may also 
affect the app’s performance or cause it to 
malfunction. Check whether data usage can 
be restricted from the app’s own settings 
(available from within the app) before re ­
stricting it here.
1. Make sure you’re viewing the network for 
which you want to view or restrict app

total data usage for the cycle displayed 
above the main graph, near the top of the 
screen.

name.
The main graph switches to show just this

out foreground versus background data 
usage for this app.
4. To stop background data usage for this 
app, check  Restrict background data .
5. Read the message that appears. If you’re 
willing to proceed, touch OK.

Advanced data usage settings
Two other settings available from the Menu 
icon can have dramatic effects—but may 
sometimes be useful:
• Data roaming can result in steep addition ­
al 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 available networks, and 
may cause some features to stop work ­
ing. This is an extreme step that should 
be used with caution.

network settings
These settings are available under  Settings >

Connect to virtual private 
networks
Vir tual private networks ( VPNs) allow entr y 
into secured local networks from the out­
side. Corporations, schools, and other insti ­
tutions use VPNs to grant access to local 
network resources when people are not on 
campus or connected to a wireless network.
To  configure  VPN  access,  you  must  first  ob ­
tain the details from your network admin ­
istrator. Depending on your organization’s 
solution, you may need to obtain a VPN app, 
either from your administrator or on Google 
Play.
The VPN settings screen al ­
lows you to add VPN networks 
and adjust their settings. To 
view this screen and perform 
the tasks described here, go to 
Settings > Wireless & networks 
> More > VPN.
