2.4 Operating Mode
Table 2-2 Operating mode
The module is registered on the network, in a standby mode, without data
transmission.
The module is connected to the network, in a working state, with data transmission in
the voice call.
The RF part of the module does not work, only the baseband part works, which is
equivalent to the function of ordinary MCU.
In this mode, the module's power consumption will be reduced to a very low level, but
the module can still receive paging, SMS, phone calls and TCP/UDP data.
Power off mode, PMU stops supplying power to the baseband and RF parts, software
