Linking to the Networks and devices
Your phone can connect to a variety of networks and devices, including mobile networks for voice and
data transmission, Wi-Fi data networks, and Bluetooth devices, such as headsets. You can also connect your
phone to a computer, to transfer files from your phone’s SD card and share your phone’s mobile data
connection via USB.
Connecting to mobile networks
When you assemble your phone with a SIM card, your phone is configured to use your provider’s
mobile networks for voice calls and for transmitting data.
Connecting to Wi-Fi networks
Wi-Fi is a wireless networking technology that can provide Internet access at distances of up to 100
meters, depending on the Wi-Fi router and your surroundings.
Touch Settings>Wireless & networks > Wi-Fi. Check Wi-Fi to turn it on. The phone scans for available
Wi-Fi networks and displays the names of those it finds. Secured networks are indicated with a Lock icon.
Note: If the phone finds a network that you connected to previously, it connects to it.
Touch a network to connect to it. If the network is open, you are prompted to confirm that you want to
connect to that network by touching Connect. If the network is secured, you’re prompted to enter a password
or other credentials.
Connecting to Bluetooth devices
Bluetooth is a short-range wireless communications technology that devices can use to exchange
information over a distance of about 8 meters. The most common Bluetooth devices are headphones for

cell phones.
Touch Settings>Wireless & networks > Bluetooth. Check Bluetooth to turn it on.
You must pair your phone with a device before you can connect to it. Once you pair your phone with a
device, they stay paired unless you unpair them.
Your phone scans for and displays the IDs of all available Bluetooth devices in range. If the device you
want to pair with isn’t in the list, make it discoverable.
Connecting to a computer via USB
