AT+CFUN=0:
Minimum functionality mode; both (U)SIM and RF functions are disabled.
AT+CFUN=1:
Full functionality mode (by default).
AT+CFUN=4:
Airplane mode. RF function is disabled.
For details of related AT commands, please refer to

AT+QCFG="airplanecontrol"
command. This command is under development.
2. The execution of
