MSISDN-C is an acronym for Mobile Subscriber Integrated Services Digital Network Number-C. A unique 12-digit number allocated to a subscriber who has subscribed to the Iridium data service. The MSISDN-C number is only used for terminating data calls to an ISU which are originated from a PSTN (land-line) phone. The MSISDN-C is comprised of a 3-digit country code, a 1-digit national destination code, a 3-digit geopolitical entity, and 5-digit line range number. Similar to it, there is also MSISDN - Mobile Subscriber Integrated Services Digital Network Number - unique 12-digit number allocated to the subscribers on the Iridium network. The MSISDN number of an Iridium subscriber is dialed by the user of PSTN, the user of PLMNs, and the other Iridium subscribers who call the Iridium subscriber. The MSISDN is comprised of a 3-digit country code, a 1-digit national destination code, a 3-digit geopolitical entity, and 5-digit line range number.

ICC-ID stands for Integrated Circuit Card Identification. It is 19 digit serial number physically printed on the SIM card. ICCID allows the SIM card inventory to be tracked.
