Troubleshooting roaming issues or behaviors
■If your iPhone 4S supports both CDMA and GSM roaming, you can use Settings > General > Network > Roaming > International CDMA to control which network your iPhone 4S uses:
■International CDMA > On: iPhone 4S will attempt to use an available CDMA network instead of GSM.
■International CDMA > Off: iPhone 4S will use only GSM networks.

■If Settings > Carrier does not appear as expected when International CDMA is enabled, force Settings to close.
