Carrier
This setting appears when youre outside of your carrier’s network and other local
carrier data networks are available to use for your phone calls, visual voicemail, and
cellular network Internet connections. You can make calls only on carriers that have
roaming agreements with your carrier. Additional fees may apply. Roaming charges
may be billed to you by the carrier of the selected network, through your carrier.
For information about out-of-network coverage and how to enable roaming, contact
your carrier or go to your carriers website.
Select a carrier: Choose Carrier and select the network you want to use.
Once you select a network, iPhone uses only that network. If the network is
unavailable, “No service” appears on the iPhone screen and you can’t make or receive
calls or visual voicemail, or connect to the Internet via cellular data network. Set
Network Settings to Automatic to have iPhone select a network for you.
Sounds and the Ring/Silent Switch
Switch between ring and silent mode: Flip the Ring/Silent switch on the side of
iPhone.
