Functionality 
Mode 
The  AT+CFUN=0  command  can  enable  the  minimum  functionality  mode  without 
removing the power supply. In this mode, both the RF function and (U)SIM card are 
invalid.   
Executing the AT+CFUN=4 command or driving the W_DISABLE1# pin to low level 
can enable the airplane mode. In this case, the RF function is invalid. 
The module keeps receiving paging messages, SMS, voice calls and TCP/UDP data 
from the network, its current consumption reduced to the minimal level.   
The  module’s  power  supply  is  cut  off  by  its  power  management  unit,  its  software 
being inactive and USB interface inaccessible while the operating voltage (connected 
to VCC) remains applied.
