base station. Tap your base station and Setup Assistant will do the rest.
Manage an AirPort network. If iPhone is connected to an AirPort base station, go to Settings > Wi-

Connect to the Internet
iPhone connects to the Internet whenever necessary, using a Wi-Fi connection (if available) or your
carrier’s cellular network. For information about connecting to a Wi-Fi network, see

When an app needs to use the Internet, iPhone does the following, in order:
Connects over the most recently used available Wi-Fi network
Shows a list of Wi-Fi networks in range, and connects using the one you choose
Connects over the cellular data network, if available
Note: If a Wi-Fi connection to the Internet isn’t available, apps and services may transfer data over
your carrier’s cellular network, which may result in additional fees. Contact your carrier for
information about your cellular data plan rates. To manage cellular data usage, see .
