Hi,
Unfortunately, it’s not possible to show the phone number in the social icons area, instead, you can insert it in the top menu using the custom link.
Here are the steps, if you want to do that:
1.Go to Dashboard->Appearance->Menus
2. Edit your top menu
3. Insert the “Custom link” to your top menu.
4. Insert the ” # ” sign as your custom link URL.
5. Insert your phone number (or whatever you like ) in “Link Text” text field.
6. Save your menu

When you reload your web page, your phone number should appear in your top menu.

In order to work properly, the phone number need to be inserted in the international format (with the prefix for your country)
e.g +33 825 30 05 00
