The
Automatic Restart after Shutdown
feature is enabled as part of the default factory settings. This
means that if/when the modem has to be switched off, due to a critical power supply, the modem
will restart itself within a few seconds. This feature allows an application to be switched on all the
time and also allows it to restart itself.

5.2
Switching off the modem
There are several ways to switch off (power down) the modem:
Using the TURN_OFF pin (see
section 4.1
to see the modems that use it). Continuously
pressing the TURN_OFF pin (for at least 1 second) causes the modem to enter power down
mode. Its use is not recommended except in an emergency. A delay of up to 10 seconds is
experienced until the modem logs out of the network. The RTC stays active.
AT^SMSO command: this allows the modem to log out of from the network and allows the
software to enter into a secure state and save data before disconnecting the power supply. A
delay of up to 10 seconds is experienced until the modem logs out of the network. The RTC
stays active.
