title: Getting the device phone number using ionic2/angular2
body: <p>I am using cordova sim plugin to get the device phonenumber, but i am getting the following error message saying:</p>
  
  <blockquote>
    <p>THREAD WARNING: exec() call to Sim.get Sim Info blocked the main
    thread for 35ms. Plugin should use CordovaInterface.getThreadPool()  </p>
  </blockquote>
  
  <p>After that SIM Info is coming null.</p>
  
  <p><strong>Could any one suggest the best approach to get the phone number?</strong></p>
