How to find out MSISDN and IMSI?

MSISDN


> What are the currently used ways of finding the 'own' MSISDN?

The MSISDN can be stored on the SIM. It's often put there by
the network provider as the first entry in the "own numbers"
phonebook. But it does not need to be stored anywhere on the
phone or SIM, and does not need to be correct if it is stored
in the above manner.

Some phones allow users to read, edit or delete these "own
number" entries via the phonebook menu. And they can usually
be read over a serial interface with "AT+CNUM" command. 
Likewise they can be deleted and added with "AT+CPBW" after
first setting the phonebook to "own numbers" with the

AT+CPBS="ON"

command.

The only absolutely reliable DIY method of establishing your
MSISDN is to call someone and look at their calling number
display, or SMS someone and look at the sender's address.

if your sim provider is UFONE simply dial the code *2# and press the dial button it will show your MSISDN number.




One mechanism if you have access to terminal software and can send AT commands (see: http://bit.ly/cwkzA7) to your mobile device, the command: AT+CIMI will return the IMSI as long as the SIM is initialized (will not return IMSI if the SIM is locked).
