9.9 AT+CLIP Calling Line Identification Presentation
AT+CLIP refers to the GSM supplementary service CLIP (Calling Line Identification Presentation) that enables
a called subscriber to get the calling line identity (CLI) of the calling party when receiving a mobile terminated call.
The AT+CLIP write command enables or disables the presentation of the CLI at the TE. It has no effect on the
execution of the supplementary service CLIP in the network.
The AT+CLIP read command gives the status of <n>, and also triggers an interrogation of the provision status
of the CLIP service according to 3GPP TS 22.081 [21] (given in <m>). If no SIM card is available or the SIM-PIN
is not entered, the command response is "ERROR".
