Mode
Details
Normal Operation
Idle
Software is active. The module remains registered on the network
and 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 to a minimum functionality mode without
removing the power supply. In this case, both RF function and (U)SIM card are
invalid.
Airplane Mode
AT+CFUN=4 or W_DISABLE# pin can set the module to airplane mode where RF
function will be invalid.
Sleep Mode
In this mode, current consumption of the module is reduced to a low level. The
module remains the ability to receive paging message, SMS, voice calls and
TCP/UDP data from network normally.
Power Down Mode
In this mode, the module’s power supply is cut off by its power management unit
(PMU). The software is inactive and the serial interfaces are inaccessible, while
the VBAT pins are still powered.
For more details about AT commands, see document [2].
