I can't find my phone, I thought it was set up on the find iPhone, but maybe not. What do I do?

Click on the link and read it to find out what to do "If your iPhone, iPad, or iPod touch is lost or stolen" --> https://support.apple.com/HT201472

- The Find My service is the only recovery feature Apple offers. It MUST be set up before the device is lost. If you did not do that it is too late to do it now and there is no other feature Apple offers that can help you find it other than you try to call or Facetime it and listen for it ringing or hope somebody answers (if somebody does, do not provide them with any private information such as your login information).
