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 join 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 conguring Wi-Fi settings, see “Wi-Fi” on page 195.
Cellular Data Network Access
iPhone can access the Internet through your iPhone carrier’s cellular network. Check
the carrier’s network coverage in your area for availability.
If iPhone is connected to the Internet via the cellular data network, the UMTS/EV-DO ( ),
EDGE ( ), or GPRS/1xRTT ( ) icon appears in the status bar.
GSM: On an EDGE or GPRS connection, you may not be able to receive calls while
iPhone is transferring data over the cellular network—downloading a webpage, for
example. Incoming calls go directly to voicemail.
CDMA: On EV-DO connections, data transfers are paused during incoming calls. On
1xRTT connections, incoming calls go directly to voicemail during data transfers.
Turn 3G on (GSM models): 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 o.
