As the SmartThings badge implies, it's about more than just keeping tabs on lost items. It can double as an arrival sensor if you have a SmartThings hub, so you can turn on the lights when you get home or activate a security camera when you leave. You can alternately set up geofencing alerts to warn when a tracker leaves a given area (say, your dog escaping the backyard) or send a location to friends and family by double-tapping the power button.

Be ready to pay more than you would for a Bluetooth tracker. Samsung's device will sell for $99 up front with a year of free service when it reaches AT&T on September 14th (a Verizon counterpart is due later in 2018), but you're looking at $5 per month or $50 per year to maintain the LTE-M connection after that. This is for people, pets and must-have belongings where the subscription is easily worth the peace of mind it brings.
