. 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.

Operating Mode Definition
The table below summarizes the various operating modes of MODULE product.
Table 35: Operating mode Definition
Mode
Function
Normal operation
GSM /UMTS/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/UMTS/LTE
Idle
Software is active. Module is registered to the network, and the
MODULE is ready to communicate.
GSM/UMTS/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, and antenna.
GPRS/EDGE/
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.
GPRS/EDGE/
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” AT+CSCLK=1 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
