How to get the IMSI number of my SIM?

Question

I am trying to get my imsi number by self. How to get that one.

Answer 1

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,

Answer 2

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.
