Connecting to the Internet

How iPhone Connects to the Internet

iPhone connects to the Internet using either a Wi-Fi network or a cellular data network. iPhone does the following, in order, until connected:

•Connects over the last Wi-Fi network you used that’s available.

•If no previously used Wi-Fi networks are available, iPhone shows a list of Wi-Fi networks in range. Tap a network and, if necessary, enter the password to join. Networks that require a password show next to them. You can prevent iPhone from automatically showing available networks. See “Wi-Fi” on page 139.

•If no Wi-Fi networks are available or you choose not to join any, iPhone connects to the Internet over a cellular data network (, , or ).

If no Wi-Fi networks are available and a cellular data network isn’t available, iPhone cannot connect to the Internet.

Note: If you don’t have a 3G connection, you cannot use the Internet over a cellular data network when you’re on a call. You must have a Wi-Fi connection to use Internet applications while also talking on the phone.
