+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 Transceiver modules 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.
