title: Href tag tel: not working
body: <p>I know this question has been asked lot of times. But I don't find a solution for my problem.</p>
  
  <p>I have a link like which I want to make an externall call from mobile view like this:</p>
  
  <pre><code>&lt;a href="tel:902 1111 111"&gt;902 111 111&lt;/a&gt;
  </code></pre>
  
  <p>But when I click on it, it's not working. 
  I'm using: <em>Java ee</em>, <em>HTML</em>, <em>CSS</em> to build my page. Any idea on why it's not working?</p>
