Apple IPhone IOS 31 User Guide

							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.
Joining a Wi-Fi Network
The Wi-Fi settings let you turn on Wi-Fi and join Wi-Fi networks.
Turn on Wi-Fi:  Choose Settings > Wi-Fi and turn Wi-Fi on.
Join a Wi-Fi network:   Choose Settings > Wi-Fi, wait a moment as iPhone detects 
networks in range, then select a network (fees may apply to join some Wi-Fi networks). 
If necessary, enter a password and tap Join (networks that require a password appear 
with a lock 
 icon).
Once you’ve joined a Wi-Fi network manually, iPhone automatically connects to it 
whenever the network is in range. If more than one previously used network is in 
range, iPhone joins the one last used.
When iPhone is connected to a Wi-Fi network, the Wi-Fi 
 icon in the status bar at the 
top of the screen shows the connection strength. The more bars you see, the stronger 
the connection.
For information about configuring Wi-Fi settings, see “ Wi-Fi
” on page 13 9 .
Cellular Data Network Access
3G, EDGE, and GPRS allow Internet connectivity over the cellular network available 
through your iPhone carrier’s wireless service. Check the carrier’s network coverage in 
your area for availability.
You can tell iPhone is connected to the Internet via the cellular data network if you see 
the 3G (
), EDGE (), or GPRS () icon in the status bar at the top of the screen.
Note:   If you don’t have a 3G connection, you may not be able to receive calls while 
iPhone is actively transferring data over a cellular network—downloading a webpage, 
for example. Incoming calls then go directly to voicemail.
Turn 3G on:   In Settings, choose General > Network and tap Enable 3G.
If you’re outside your carrier’s network, you may be able to access the Internet through 
another carrier. To enable email, web browsing, and other data services whenever 
possible, turn Data Roaming on.
Turn Data Roaming on:   In Settings, choose General > Network and turn Data 
Roaming on.
Important:   Roaming charges may apply. To avoid data roaming charges, make sure 
Data Roaming is turned off.

iPhone may turn on VPN automatically whenever it’s needed. Contact your system 
administrator for more information.

For best results, speak the full name of the person you’re calling. If you give only the 
first name, and you have more than one contact with that same name, iPhone asks 
which of those contacts you want to call. If there’s more than one number for the 
person you’re calling, specify which number to use. If you don’t specify which number, 
iPhone asks you which one to use.
When voice dialing a number, speak each digit separately—for example, say “four one 
five, five five five, one two one two.”
Note:  For the “800” area code in the U.S., you can say “eight hundred.”
Prevent voice dialing when iPhone is locked:   In Settings, choose General > Passcode
