5 Make Sure Find My iPhone Is Enabled
Find My iPhone is an invaluable tool for finding a handset that’s slipped under the couch or car seat. But it’s also an essential feature for finding a handset that’s been lost or stolen. This goes without saying, but it’s incredibly important to enable it.
The feature is typically turned on during iPhone setup but there’s the option to skip it. Similarly, there are certain instances where Find My iPhone could be switched off.
Either way, make sure it’s enabled by going to Settings > Your Apple ID card > iCloud > Find My iPhone. While you’re at it, make sure to turn Send Last Location on, too.
