AirTags and Tile Pro work fine wherever there are other people. They're not going to work in the Atacama.
They worked fine every time I used them. I recently sent a laptop to France and included one of each. Sometimes the Tile pinged and sometimes the AirTag pinged, but they worked really well across continents.
I also have about 4 of each in a vehicle left unattended for a while in a parking garage that doesn't have a great deal of people around it. And all of them ping at least once a day. The Tile Pros have ~100m LoS range which are quite a bit more than previous ones from years ago.
The other was the time I left my car keys on top of my car. Someone took the keys and put them in a random nearby business’s lost and found. The tile never pinged over the course of days and I had to find it the old fashioned way.
These things never worked for me, but it’s good to know that mail delivery people use these apps/devices that will let you track your packages in realtime.
Lesson: Don't lose shit.
