Steps to retrieve the IMSI number

IMSI stands for Inernational Mobile Subscriber Identity and this can be used to uniquely identify the SIM and mobile phones use it to register with mobile network.

If you can enumerate your mobile phone as a modem and using the corresponding COM port in the Hyperterminal utility in windows you can retrieve the IMSI number.It is required to use AT ( stands for attention ) commands to get the IMSI of the SIM in the device.

You can google for the AT command list, I don’t want to keep this post in drafts anymore, so I have to ask you to google for AT commands 🙂
