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’re using an original iPhone, 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.
Many Wi-Fi networks can be used free of charge including, in some regions, Wi-Fi
hotspots provided by your iPhone carrier. Some Wi-Fi networks require a fee. To join a
Wi-Fi network at a hotspot where charges apply, you can usually open Safari to see a
webpage that allows you to sign up for service.
