remove view profile

Hello.,

I have the following problem.

When I try to go to my page without doing registration and choose to see one classified, when the classified open up, the page to the right there is a field that writes “ view profile ” and you see the username and the mobile number.
I want when i don’t register to the page I can not see the mobile number . If this is difficult to do then i want not to see the field ” view profile” .
