*Note: Module is able to make and receive voice calls, data calls, SMS and make
WCDMA/HSPA+/LTE traffic in -40℃ ~ +85℃. The performance will be reduced slightly from
the 3GPP specifications if the temperature is outside the normal operating temperature range
and still within the extreme operating temperature range.
5.3 Operating Mode
5.3.1 Operating Mode Definition
The table belowsummarizes the various operating modes of Module series products.

Mode
Function
Normal operation
GSM/WCDMA / LTE
Sleep
In this case, the current consumption of module will be reduced to the
minimal level and the module can still receive paging message and
SMS.
GSM/WCDMA / LTE
Idle
Software is active. Module is registered to the network, and the
module is ready to communicate.
GSM/WCDMA / LTE
Talk
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.
GSM/WCDMA/LTE
Standby
Module is ready for data transmission, but no data is currently sent or
received. In this case, power consumption depends on network
settings.
GPRS/EDGE/WCDM
A / LTE transmission
There is data transmission in progress. In this case, power
consumption is related to network settings (e.g. power control level);
uplink/downlink data rates, etc.
Minimum functionality
mode
AT command “AT+CFUN=0” can be used to set the module to a
minimum functionality mode without removing the power supply. In
this mode, the RF part of the module will not work and the USIM
card will not be accessible, but the serial port and USB port are still
accessible. The power consumption in this mode is lower than normal
mode.
Flight mode
AT command “AT+CFUN=4” or pulling down the FLIGHTMODE
pin can be used to set the module to flight mode without removing the
power supply. In this mode, the RF part of the module will not work
but the serial port and USB port are still accessible. The power
