> • | The value of \Q (flow control) is also determined by the AT+IFC command. In case the value set by AT+IFC cannot be represented by a \Q equivalent, \Q255 will be displayed.

> • | The parameters of AT^SMGO can only be displayed after the SMS data from the SIM have been read successfully for the first time. Reading starts after successful SIM authentication has been performed, and may take up to 30 seconds depending on the SIM used. While the read process is in progress, an attempt to read the parameter will result in empty values.

> • | The parameter of AT+CSDH will only be displayed in SMS PDU mode, see AT+CMGF.
