In sleep mode, the module can still receive paging message, SMS, voice call and TCP/UDP data from the
network normally.
3.5.2. Minimum Functionality Mode
Minimum functionality mode reduces the functionality of the module to minimum level, thus minimizes the
current consumption at the same time. This mode can be set as below:
Command
AT+CFUN
provides the choice of the functionality levels: <fun>=0, 1, 4.
⚫
AT+CFUN=0
: Minimum functionality, RF part and (U)SIM card will be closed.
⚫
AT+CFUN=1
: Full functionality (by default).
⚫
AT+CFUN=4
: Disable RF function (airplane mode). All AT commands related to RF function are not
accessible.
