In this case, the current consumption of module will
bereduced to the minimal level.
In sleep mode, the module can still receive paging
message and SMS.

Idle
Software is active. Module is registered to the
GSM/WCDMA/TD-
SCDMA/EVDO/LTE network,
andthe module is ready to communicate.

/TD-SCDMA/EVDO)
taking
Connection between two subscribers is in progress.
In thiscase, the power consumption depends on
network settings such as DTX off/on, FR/EFR/HR,
hopping sequences, antenna.

-SCDMA/EVDO/LTE)
Standby
Module is ready
forGPRS/EDGE/WCDMA/TD-SCDMA/EVDO/LTE
data transfer, but no data is currently sent or
received. Inthis case, power consumption depends
on network settings and EDGE/HSPA+ /LTE
configuration.

-SCDMA/EVDO/LTE)
Data transfer
There
isGPRS/EDGE/WCDMA/TD-SCDMA/EVDO/LTE
data transfer in progress. In this case, power
consumptionis related to network settings (e.g. power
control level); uplink/downlink data rates and GPRS
configuration (e.g. used multi-slot settings).
Minimum mode
AT command “AT+CFUN” can be used to set the
module to a minimum functionality mode without
