How to track an iphone without find my phone?

UHGG! I lost my phone and I do have icloud, but did not setup my find my phone app. I called my service (verizon), apple inc., and even the police station. No one can find anything? Some Computer wiz must know what to do…

Ok in the phone is a serial number. So say you want to sell your phone but you have to pay for an deactivation fee you won't be able to sell it cuz that serial number still belongs to you so the person your trying to sell it won't be able to put a service on it. Anyways if you didn't hook up iCloud and didn't set up find my phone the I'm sorry to say this but there's nothing you can do. I'm really sorry.
