I want to know if you are connected to your home wifi, and that wifi temporarily loses signal for a few hours, does the iPhone automatically start using your cellular network?
I had an issue with my Find Friends App not showing my location for a while, even though I never shut it off. I am just wondering if this could be the cause.

This has changed since iOS 9 with Wi-Fi Assist
Prior to iOS 9…
No, unfortunately not.
If the WiFi signal itself is still 'live' the iPhone doesn't check to see if it's actually connected to the outside world, unfortunately. It will just spin its wheels waiting for data that never arrives.
You need to switch it over manually.
