3.4. Operating Modes
The table below briefly summarizes the various operating modes referred in the following chapters.
Table 5: Overview of Operating Modes
Software is active. The module has registered on the network, and it is
ready to send and receive data.
Network connection is ongoing. In this mode, the power consumption is
decided by network setting and data transfer rate.
Minimum
Functionality
Mode
AT+CFUN command can set the module to a minimum functionality mode without
removing the power supply. In this case, both RF function and (U)SIM card will be
invalid.
AT+CFUN command or W_DISABLE# pin can set the module to airplane mode. In
this case, RF function will be invalid.
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.
In this mode, the power management unit shuts down the power supply. Software is
not active. The serial interface is not accessible. Operating voltage (connected to
VBAT_RF and VBAT_BB) remains applied.
