Mous cases for the Samsung Galaxy S21: Drop protection and magnetic accessory features
Before you do anything on your iPhone or iPad, you should lock it down. This is how you do it.
Apple's Find My iPhone tells you where your device is if you mark it lost or stolen.
Head to Settings, then tap your name at the top, then go to iCloud, then Find My iPhone, (or iPad) and make sure that it is switched on. You may need to enter your device passcode to authorize this.
Also, by selecting Send Last Location, with the last few percent of battery life, your device will update Apple's servers with its last location -- just before it powers down.
