Go to Settings > Carrier to select a carrier network. This setting appears on GSM networks when
you’re outside 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 a roaming agreement with your carrier. Additional fees may apply.
Roaming charges may be billed to you by the other carrier, through your carrier.
Once you select a network, iPhone uses only that network. If the network is unavailable, “No
service” appears on the iPhone.
