MSISDN
MSISDN (Mobile Station International ISDN Number) is a number uniquely identifying a subscriber in a GSM or UMTS mobile network. Simply put, it is the telephone number to the SIM card in a mobile phone. The IMSI and the MSISDN are two important numbers used to identify a mobile phone. Whereas the IMSI (used within the SIM card in all GSM mobile phones, to uniquely identify the mobile subscriber on a specific mobile network) is often used as a key in the HLR ("subscriber database"), the MSISDN is the number normally dialed to connect a call to the mobile phone.
