I have connected my PC to the GSM Modem with data cable. Now I want to know the Unique Identification no. of SIM. Is there any command to get it? What is that?
If there is a command to get the Unique SIM Identification no. then what is the relation between the Phone number of that SIM and SIM unique identification number.
What is the use of ?AT+CNUM?? In AT-Help it says that it is used to get the subscriber number but it only says OK, why?
AT+CIMI tells us the IMSI of SIM then how to get the Subscribers number from this.
Grateful to any posting on this issue,
