Your iPhone may connect to the internet via either local Wi-Fi networks or your cellular data network.
If Wi-Fi is turn off or unavailable, then the cellular data network will take over when available…and will allow you to use Mail, Safari, YouTube, Stocks, Maps, Weather, the iTunes Store and the App Store.
To Turn Wi-F on or off, simply choose Wi-Fi then select on or off.
To Join a Wi-Fi network, choose Wi-Fi, wait a moment as iPhone detects networks in range, then select a network.
Enter password, if necessary, and tap Join. (Networks that require a password appear with a lock icon.). If you don’t have a password you will need to get one from the network administrator.
Join a Wi-Fi network once and your iPhone automatically connects to to it whenever you are in range.
If you’ve joined multiple networks and is in range of all, your iPhone will connect to the last one used.
You know you’re connected to Wi-Fi network when the Wi-Fi icon in the status bar at the top of the screen shows signal strength. The more bars you see, the stronger the signal.
To set your iPhone to “ask if you want to join a new network,” choose Wi-Fi and turn “Ask to Join Networks” on or off.
When necessary, you iPhone will displays a list of available Wi-Fi networks that you can choose from.
To ‘un-join’ a network, choose Wi-Fi and tap Blue dot with right arrow next to a network you’ve joined before. Then tap “Forget this Network.”
To join a closed Wi-Fi network that’s not listed, choose Wi-Fi, then Other, then enter the network name. If the network requires a password, tap Security, tap the type of security the network uses, and enter the password.
You must already know the network name, password, and security type to connect.
If additional settings are required, ask the network administrator.
