Operating Mode
Description
Shutdown
When the VBAT pin of the module is not powered or the power
voltage is lower than 3 V, the module is in a shutdown state.
Standby
The module is powered on, and it can be operated using the AT
commands through the serial port. The module is registered with the
network, there is no service processing in progress, and the module is
ready for communication. This is the default operating mode after the

module is powered on.
Transmission
The module is powered on and successfully registered with the
network for service transmission. The module can be operated using
the AT commands through the serial port. The module transmits data.
When data transmission is completed, the module returns to the
standby or low-power mode.
Sleep
The module is in light sleep state. It is connected to a network and
can receive paging messages. In this mode, the module can switch to
the standby mode or PSM mode.

In the limited operating temperature range, some RF indexes may exceed the standard. It
is suggested that the temperature control measures should be considered in the
application end under the harsh environment. At the same time, it is suggested that the
module application terminal should be stored at a certain temperature. Beyond this range,
the module may not work properly or be damaged.
2.6 Reliability Indicators
To improve the reliability and stability of the product, the module has been tested for
reliability as shown in the table below.
