AT^SMSO Switch off mobile station
initiates the power-off procedure. Low level of the module's VDD pin and the URC "^SHUTDOWN" notify
AT^SMSO
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 or until the URC "^SHUTDOWN" is displayed. Otherwise,
you run the risk of losing data. For further details on how to turn off the module see the [2].

Notes
•
Do not send any other AT command after AT^SMSO.
•
If AT^SMSO is entered on one of the Multiplexer channels the ME closes the Multiplexer channels, terminates
the Multiplexer and deactivates all other functions. Then, the URC "^SHUTDOWN" will be issued on the phys-
ical serial interface (ASC0). The URC will be transmitted at the bit rate last activated on ASC0 for use with
the Multiplex driver.
•
If both interfaces ASC0 and ASC1 are connected the URC appears on both of them.
