*Note: Module is able to make and receive voice calls, data calls, SMS and make UMTX/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 below summarizes the various operating modes of Module product.

Mode Function
Normal operation
UMTS/LTE Sleep
AT command “AT+CSCLK=1” can be used to set the module to a
sleep mode. In this case, the current consumption of module will be
reduced to a very low level and the module can still receive paging
message and SMS.
UMTS/LTE Idle
Software is active. Module is registered to the network, and the
Module is ready to communicate.
UMTS/LTE Talk
Connection between two subscribers is in progress. In this case, the
power consumption depends on ne
twork settings such as DTX
off/on, FR/EFR/HR, hopping sequences, and antenna.
UMTS/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.
UMTS/LTE
Data 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
