Wi-Fi network
A Wi-Fi network connection allows your device to use data services, but unlike using the mobile network, using Wi-Fi
doesn't add charges to your data plan.
When you connect to a Wi-Fi network, your device saves the network information. The next time your device is within range
of the saved Wi-Fi network, and Wi-Fi is turned on, your device can connect to the network automatically.
Your device can be connected to the mobile network and a Wi-Fi network at the same time. For basic data functions, such
as using the Internet or downloading apps, your device is designed to try to use a saved Wi-Fi network before it tries to use
the mobile network. Keep in mind that if you leave Wi-Fi turned on, your battery might lose power more quickly.
Connect to a Wi-Fi network
1. Swipe down from the top of the screen once using two
fingers, or twice using one finger.
2.
Tap > Wi-Fi.
3. If necessary, turn on the switch.
4. Tap a network.
5. If necessary, do one of the following:
• Enter the password for the Wi-Fi network, and then tap Connect.
• To connect to a Wi-Fi network at work, enter your username and password, and then tap Connect.
• To connect to a public network, tap the sign-in
notification and, if necessary, accept the license agreement. If
necessary, tap > Use this network as is.
Add a Wi-Fi network manually
If your device doesn't connect automatically to a saved Wi-Fi network, you can set up a connection to a Wi-Fi network
manually. If you don't have the required information, ask your network administrator or the person who manages the Wi-Fi
network.
1. Swipe down from the top of the screen once using two fingers, or twice using one finger.
2.
Tap > Wi-Fi.
3. If necessary, turn on the switch.
4.
Tap > Add network.
5. In the Network field, type the SSID for the network.
