   Note: To optimize battery life, turn Wi-Fi off when not in use. To manage whether your device automatically switches from a poor or unstable Wi-Fi network to the AT&T network to maintain a consistent data connection, tap the Smart network switch. When using the AT&T network, data rates apply.
   
5. While Wi-Fi is enabled, and connected to a network, the Wi-Fi icon will be displayed in the notifications bar.
   
6. Tap the desired network to connect to.
   Note: Scroll down and tap 'Add Wi-Fi network' to connect to a hidden or unbroadcasted Wi-Fi network. You will need to enter the network SSID, security type, and a password (if necessary) to continue.
   
7. If prompted, enter the required password, then tap CONNECT.
   Note: Secure networks will display with a Lock icon. Data transmitted over a Wi-Fi network does not count toward your AT&T data plan, and will not be billed.
