queried with the +CVMI command.

Exec Command: +CICCID
Query the status ICC ID of the sim:
+CICCID
This returns the 19 or 20 digit Integrated Circuit Card Identification of the sim

seconds after startup.
10.8 +CLIP – Calling Line Identification Presentation
Exec Command: +CLIP=<n>
Note: While this command is implemented in Iridium ISU, it may not yet be supported in the Iridium
network. Stand by for an Iridium Technical Bulletin announcing network support for this feature.
This command controls the presentation of the Calling Line Identity of the calling party in a mobile
terminated call via the +CLIP unsolicited result code. <n> controls only the presentation of the
unsolicited result code; the delivery of Calling Line Identity information to the ISU is controlled by the
provisioning of the CLI Presentation supplementary service in the network.
Note that presentation of Calling Line Identity by the +CLIP AT command at the serial port is independent
of MMI display of integrated phone handsets such as 9555 of 9505A. Phone display presentation of Calling
Line Identity on these products is not controlled by the +CLIP command.
