How to get Device Information such IMEI,IMSI No,Brand Name,manufacture name, Software Version , Sim Serial No

Firsr Activity Java Code:-

public class SystemInfo extends Fragment
{
TextView txtManufacture;
Context context;
public SystemInfo(Context ctx)
{
this.context=ctx;
}
@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState)
    {

DeviceInfoDao deviceInfo=new DeviceInfoDao();
deviceInfo=DeviceInfoDao.getDeviceInfo(context.getApplicationContext());
        View rootView = inflater.inflate(R.layout.system_info, container, false);
        txtManufacture=(TextView)rootView.findViewById(R.id.manufacture);
     
        txtManufacture.setText(deviceInfo.manufacturer);
        return rootView;
     
    }

}
