getLine1Number() is not working

Question

I want to get The SIM phone number using android but when I get The number the length is zero! here is the code:

TelephonyManager mTelephonyMgr = (TelephonyManager) getSystemService(getApplicationContext().TELEPHONY_SERVICE);
String s=mTelephonyMgr.getLine1Number();
Toast.makeText(getBaseContext(), "The length is "+s.length(), Toast.LENGTH_LONG).show();

but it will Toast " The length is zero". When I print the number it will print nothing. Can anyone give me a solution?

do you have SIM inserted or you are testing it in Emulator ? — Lucifer, Nov 06 '12 at 12:59
`getLine1Number()` returns the phone number off the SIM card. Sometimes the phone number is on the SIM card, some times it isn't. And sometimes it is wrong. The only sure way to get the user's phone number is to ask him for it. — David Wasser, Nov 07 '12 at 12:46

Get SIM Number

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

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

I've also seen this issue, it is highly SIM and device dependant. You can't guarantee that Android will be able to provide you the device phone number. – Guykun Nov 06 '12 at 14:00
