Your HTML is invalid. You have to remove extra spaces:
<li><i class="fa fa-phone"></i>+2 95 01 88 821</li>
<li><i class="fa fa-envelope"></i>[email protected]</li>
Tag names are usually in lowercase.
Hope you have CSS describing your classes fa, fa-envelope and fa-phone…
Update
As I understand from your comments you have no CSS and font Awesome for your HTML. So you have to add them.
As @cjslv recommended, please look at http://fontawesome.io
Also I’d suggest you to refresh your HTML and CSS skills.
