both RF part and USIM card will be closed, and the serial port is still
accessible. The power consumption in this mode is lower than normal mode.

Module will automatically go into sleep mode if the
conditions of sleep mode are enabling and there is no on air
and no hardware interrupt (such as USB wake-up operation 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
and SMS.
Software is active.
GSM/WCDMA/LTE 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
such as DTX off/on, FR/EFR/HR, hopping sequences,
antenna.
Module is ready for EDGE/HSPA+ /LTE data transfer, but no
data is currently sent or received. In this case, power
consumption depends on network settings and EDGE/HSPA+
/LTE configuration.
There is EDGE/HSPA+/LTE data transfer in progress. In this
case, power consumption is related to network settings (e.g.
power control level); uplink/downlink data rates and GPRS
configuration (e.g. used multi-slot settings).
