The table below briefly summarizes the various operating modes referred to in the following 
chapters.

Table 7:  Overview of operating modes

Normal 
operation

GSM / GPRS / 
UMTS / HSPA /
LTE SLEEP

Power saving set automatically when no call is in progress and the USB 
connection is detached and no active communication via ASC0. Also, 
the GNSS active antenna mode has to be turned off or set to "auto".

GSM / GPRS / 
UMTS / HSPA / 
LTE IDLE

Power saving disabled or an USB connection active, but no data trans-
fer in progress.

GPRS DATA

GPRS data transfer in progress. Power consumption depends on net-
work settings (e.g. power control level), uplink / downlink data rates and 
GPRS configuration (e.g. used multislot settings).

EGPRS DATA

EGPRS data transfer in progress. Power consumption depends on net-
work settings (e.g. power control level), uplink / downlink data rates and 
EGPRS configuration (e.g. used multislot settings).

UMTS DATA

UMTS data transfer in progress. Power consumption depends on net-
work settings (e.g. TPC Pattern) and data transfer rate.

HSPA DATA

HSPA data transfer in progress. Power consumption depends on net-
work settings (e.g. TPC Pattern) and data transfer rate.

LTE DATA

LTE data transfer in progress. Power consumption depends on network 
settings (e.g. TPC Pattern) and data transfer rate.

Power 
Down

Normal shutdown after sending the AT^SMSO command. Only a voltage regulator is active 
for powering the RTC. Software is not active. Interfaces are not accessible. Operating volt-
age (connected to BATT+) remains applied.

Airplane 
mode

Airplane mode shuts down the radio part of the module, causes the module to log off from 
the GSM/GPRS network and disables all AT commands whose execution requires a radio 
connection.
Airplane mode can be controlled by AT command (see
