Get Mobile Number of Sim Card on Android Device

You can use the TelephonyManager to do this:
TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE); 
String number = tm.getLine1Number();
The documentation for getLine1Number() says this method will return null if the number is "unavailable", but it does not say when the number might be unavailable.
You'll need to give your application permission to make this query by adding the following to your Manifest:
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
(You shouldn't use TelephonyManager.getDefault() to get the TelephonyManager as that is a private undocumented API call and may change in future.)


Activity Class Look Like This

package com.kns;
import android.content.Context;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.widget.Toast;
public class GetMyPhoneNoActivity extends Activity {
    /** Called when the activity is first created. */
    public void onCreate(Bundle savedInstanceState) {
        String number =getMyPhoneNO();
        Toast.makeText(getApplicationContext(), "My Phone No is: "
        +number, Toast.LENGTH_SHORT).show();
        Log.v("Debug", number);        
    private String getMyPhoneNO(){
     TelephonyManager mTelephonyMgr;  
     mTelephonyMgr = (TelephonyManager) getSystemService
     String yourNumber = mTelephonyMgr.getLine1Number();
  return yourNumber; 

Permission in Manifest File
<uses-permission android:name="android.permission.READ_PHONE_STATE">
