Cfun, Shut Down Phone Functionality - Motorola G24 Guide Developer's Manual

Hardware Information

+CFUN, Shut Down Phone Functionality

This command shuts down the phone functionality of smart phones and PDAs with phone
capabilities in order to prevent interference from a nearby environment. This enables other
functionality to continue to be used in environments where phone use is either impractical or not
permitted. For example, on airplanes the use of cellular phones is forbidden during the entire
flight, but the use of computers is allowed during much of the flight. This command enables other
functionality to continue while preventing use of phone functionality.
