I lost my iPhone and I didn't have Find my iPhone enabled. How can I track it down for free? - 1

Added (1). I have a lot of info on my phone that I'd like to get back.

You can get it back for free just like you lost it.

For Free of course!

You can't

Ever heard of the phrase, "As much use a shutting the stable doors after the horse has bolted"?

You failed to enable the most useful totally free tool provided on the phone. If you didn't enable Find My iPhone then I'll assume that you also failed to back up your precious data and didn't set it to back up automatically to iCloud. Bye bye phone, goodbye data.

Search every space in your house. Call it again and again. Check EVERYWHERE! And I mean EVERYWHERE! I lost my phone once and found it in between the tiny spaces of my couch. It was lost for a day but I found it.
Just hope it's not on silent. If it is, look for light, phones usually turn on when called.
Just hope it doesn't have brightness down all the way, if it is then you have to look EVERYWHERE!
Just hope it hasn't been shut down or died, if so, again, look EVERYWHERE!
Should turn up soon. GOOD LUCK!
Did you find it? It's been a little since you asked the question

You can't. There's nothing on the phone by itself to do that & as you stated you didn't enable Find My iPhone which would have been the only help in this case.

You need to track with a reliable tracking app like iKeyMonitor.

No you can't. You should have enable Find my iPhone…

Nothing you can do about it.

LOOK for it.
