As far as SIM has a number written on top of it, but that number is not the IMSI, but it is a representation of it (for security reasons).

There is no way to know your complete IMSI number without inquiring your service provider. They use an algorithm to convert that number into the IMSI. With access to the HLR or if a tech performs a call trace, you can find the SIM's IMSI.

So in summary you can not find IMSI number by just having the SIM.

@salil Can we get IMSI on demand to service provider
As far as I know by law they are not bound to share (just check), however this can vary from country to country.
@salil  I have bought new Docomo sim, In the welcome kit inaddition to mobile number, they have printed the IMISI also. Hope IMSI is not confidential number, it is public one, I am not sure,
cool, I will also check if I can locate my old kit. New learning for me...:)
IMSI nuber is a 15 digit number..sim manufacturers wont provide imsi number in ur mobile..

Hi, I am not sure about the legal details. However I believe there is an option to get IMSI number.

Refer this link - this java class has methods to retrieve IMSI code. (Even works for Dual SIM!!)

getStringOfInt(context, "<predictedMethodName>", 0);
getStringOfInt(context, "<predictedMethodName>", 1);

Actually, the lines of code provided above retrieves the information we request. You may have to try additional predicated method names, if the provided methods doesn't work for you.

Hope this helps.

IMSI and MSISDN are used to denote the mobile in some sense i.e. Sim Identification or User identification. My question is why we have two numbers, is there any relation between these i.e. can we deduce IMSI from MSISDN or vice versa. Is it necessary to have both numbers or there can be cases when only one number is available or applicable.

I am looking for ways for a GSM/3G device to be able to automatically select the appropriate GPRS/Data settings for customer SIM cards, particularly where a service provider offers different parameters for different account types?

Is this possible, or will I need to code the device to try multiple parameter sets until successful?
