Add phone number in secondary menu with icon

Please add the span html inside the secondary menu text as :

<span class='icon-phone'></span>0437 445 352 

As can be seen in this screenshot: http://prntscr.com/47l3c0 .

And then add this to custom css:

body span.icon-phone {
    background: none;
    height: 10px;
    line-height: 10px;
    font-size: 26px !important;
