Module can be powered down by the AT command "AT+CPOF" or the POWER_ON
pin. The power management unit shuts down the power supply of the module, only the
Power down
power supply of RTC is remained. The serial interface is not accessible. Operating
voltage (connected to VBAT) remains applied.
The AT command "AT+CFUN" can be used to set the module to a minimum
Minimum
functionality mode without removing the power supply. In this mode, the RF part of
functionality
the module will not work or the SIM card will not be accessible, or both will be closed,
mode
and the serial port is still accessible. The power consumption in this mode is very low.

Module will automatically enter SLEEP mode if DTR is set to high
level and there is no on air or hardware interrupt (such as GPIO
interrupt or data on serial port).
In this case, the current consumption of module will be reduced to the
minimal level.
In SLEEP mode, the module can still receive paging message，voice
call and SMS.
Software is active. Module has registered to the GSM network, and
the module is ready to communicate.
Connection between two subscribers is in progress. In this case, the
power consumption depends on network settings (DTX off/on,
FR/EFR/HR, hopping sequences, etc.) and antenna.
Module is ready for GPRS data transfer, but no data is currently sent
or received. In this case, power consumption depends on network
settings and GPRS configuration.
There is GPRS data transfer (PPP or TCP or UDP) in progress. In this
case, power consumption is related with network settings (e.g. power
control level), uplink/downlink data rates and GPRS configuration
(e.g. used multi-slot settings).
Module is ready for data transfer in EDGE mode, but no data is
currently sent or received. In this case, power consumption depends
on network settings and EDGE configuration
There is EDGE data transfer (PPP or TCP or UDP) in progress. In this
case, power consumption is related with network settings (e.g. power
control level), uplink/downlink data rates and EDGE configuration.
Module has registered to the WCDMA network, and the module is
ready to communicate.
Module is active in WCDMA mode. The power consumption depends
on network settings.
Module is ready for data transmission, but no data is currently sent or
received. Power consumption depends on network settings and
HSDPA configuration
There is HSDPA data transfer (PPP or TCP or UDP) in progress. In
this case, power consumption is related with network settings (e.g.
power control level), uplink/downlink data rates and HSDPA
configuration
