I am using the code 

TelephonyManager tMgr =(TelephonyManager)mAppContext.getSystemService(Context.TELEPHONY_SERVICE);
  mPhoneNumber = tMgr.getLine1Number();

to get the phone no programatically in android . But this is working fine only for one sim card. If i test this code by inserting other sim card, it is giving null. I am trying to find the solution for this. please help me. I have also included READ_PHONE_STATE permission in Manifest.

I want to uniquely identify the sim card. IS there any other way to do this. please let me know.

I think Sim serial Number is unique. You can try this.

TelephonyManager telemamanger = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
String getSimSerialNumber = telemamanger.getSimSerialNumber();

Let me know if there is any issue.
