3 Operating Characteristics
3.1. Operating Modes
The table below outlines operating modes of the module.
Table 7: Overview of Operating Modes
The module remains registered on network, and is ready to send
and receive data. In this mode, the software is active.
The module remains registered on network, and is ready to send

Extended Idle Mode
DRX (e-I-DRX)
The module and the network may negotiate over non-access stratum signaling
the use of e-I-DRX for reducing power consumption, while being available for
mobile terminating data and/or network originated procedures within a certain
delay dependent on the DRX cycle value.
AT+CFUN=4 or W_DISABLE# pin can set the module into airplane mode where
the RF function is invalid.
Minimum
Functionality Mode
AT+CFUN=0 can set the module into a minimum functionality mode without
removing the power supply. In this mode, both RF function and (U)SIM card are
invalid.
The module remains the ability to receive paging message, SMS* and TCP/UDP
data from the network normally. In this mode, the current consumption is reduced
to a low level.
The module’s power supply is shut down by its power management unit. In this
mode, the software is inactive, the serial interfaces are inaccessible, while the
operating voltage (connected to VBAT_BB and VBAT_RF) remains applied.
PSM is similar to power-off, but the module remains registered on the network
and there is no need to re-attach or re-establish PDN connections. The current
consumption is reduced to a minimized level.
The module can burn firmware with an empty serial flash, or recover from
firmware malfunction. For more details, see Chapter 3.6.
