Operating Modes
The table below briefly summarizes the various operating modes referred in the following chapters.
Table 6: Overview of Operating Modes
Mode
Details
Normal Operation
Idle
Software is active. The module has registered on the network, and it is
ready to send and receive data.
Talk/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=0
can set the module into a minimum functionality mode without removing
the power supply. In this case, both RF function and (U)SIM card will be invalid.
Airplane Mode
AT+CFUN=4
can set the module into 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.

Sleep Mode
The module is able to reduce its current consumption to a minimum value during the sleep mode. This chapter
mainly introduces some ways to enter or exit from sleep mode. The diagram below illustrates the current
consumption of the module during sleep mode.
