    The working mode of SMS server function.

    • 0 - Disable. SMS will not be used for data transmission.

    • 5 - Force on SMS mode. Only SMS is used for data transmission. In this mode, the network backend server function (configured by the AT@BSS command) will be invalid, that is, the terminal does not connect to the network backend server.

  • SMS Gateway Number

    The gateway number of SMS. If it is an international number, remember to add “+” and the area code. Note that this field will be ignored when the ‘SMS Mode’ is 0.
