Airplane
Mode
AT+CFUN=4 or W_DISABLE# pin can set the module to airplane mode. In this case, RF
function will be invalid.
Sleep Mode
In this mode, the current consumption of the module will be reduced to the minimal level.
During this mode, the module can still receive paging message, SMS, voice call and
TCP/UDP data from the network normally.
Power down
Mode
In this mode, the power management unit shuts down the power supply. Software is not
active. The serial interfaces are not accessible. Operating voltage (connected to
VBAT_RF and VBAT_BB) remains applied.
