7.23 AT^SMSO Switch off mobile station
Test command
AT^SMSO=?
Response
OK
Execute command
AT^SMSO
Response
^SMSO: MS OFF
OK
After this response, the power-off procedure will start. The low level of the
module’s VDD pin verifies that the procedure has completed and the module
has entered the POWER DOWN mode. Therefore, be sure not to disconnect
the operating voltage until VDD is low. Otherwise, you run the risk of losing
data. For further details on how to turn off the module see [1].
If you are using the TC35i Terminal, where the module’s VDD pin is not acces-
sible, you are required to wait 10s after sending AT^SMSO before switching off
the power supply at the PLUS pin of the TC35i Terminal. This time is needed to
safely log off from the network and finish saving to the internal memory. For fur-
ther details see [2].

Do not send any further AT command after AT^SMSO.
