How to fiind my Iphone without the app?

I lost my iphone but i have the find my iphone app. I don't think its not activated but i have icloud. Is there anyway i can find it? Track it? I have a iphone 4.

If its around your house, just call your phone.
If its on silent mode… Oh well

Or
you could retrace your steps and go back to the places you went to…

But thats the only ways that I know.
