How to fetch own mobile number in android [duplicate]

Answer 1

Can do this:

TelephonyManager mTelephonyMgr;  
mTelephonyMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);   

String yourNumber = mTelephonyMgr.getLine1Number();  

Add Permission to Manifest file:

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

Answer 2

I think there are cases where the phone does not know its own number - it somehow depends on the network provider / SIM card.

I do have one SIM card where it works, another one (different provider, prepaid) where it does not work.

Answer 3

Try the following code:

TelephonyManager mTelephonyMgr =
(TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);

String sDeviceID = mTelephonyMgr.getDeviceId();
String sSimSerial = mTelephonyMgr.getSimSerialNumber(); 

Set the following permission

android.permission.READ_PHONE_STATE in Android Manifest file
