what is the USSD to get mobile number

Question

i have an android application which requires to get the mobile number. i tried this

TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        String number = tm.getLine1Number();

but it returns null, after I read the documentation of the TelephoneManager I understood that some phones don't have the mobile number they are working on.

the solution was to send an USSD code to get it.

I couldn't find that, any help please?

You mean by carrier don't you? USSD is implemented by the carrier- it actually makes a "call" to a remote server to respond. You can write simple client server apps in USSD, and did in the bad old days. — Gabe Sechan, Jun 14 '13 at 19:25

USSD isn't really supported in Android. But even if you can get it to work, USSD codes vary by carrier
