How Bluetooth Item Trackers Find Things Beyond Bluetooth Range

A small tracker attached to keys or luggage usually has no mobile-data plan and may not have GPS. Yet its app can sometimes show a location even when the tracker is far from your phone. That can make the device seem as if it has a long-range radio hidden inside it. The useful mental model is different: the tracker does not need to reach your phone directly if another compatible device can notice it and report its location through a finding network.
