Basics 

Connecting to the Internet 

iPhone connects to the Internet automatically whenever you use Mail, Safari, YouTube, 
Stocks, Maps, Weather, the App Store or iTunes Wi-Fi Music Store. 

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

Â

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 100. 

  

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  ). You cannot access the iTunes 
Wi-Fi Music Store over a cellular data network. 

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.
