my parents live in Russia and my grandma has alzheimer's, so as a present "for her" I bought an airtag - so in case my mom loses grandma in a crowd she can be found.
Little did I know, GPS jammers around the city make my grandma appear 50km away.
Not Apple's fault of course.
The AirTag does not have a GPS receiver. When anyone's iPhone discovers the tag, it sends their device's location to Apple servers with "by the way, this AirTag is in range." If cellular location is inaccurate then good luck.
iPhone SE for next gift? it can snap back to correct location when the jammers are off or the phone infers location from tower etc
AirTag itself doesn't have GPS, of course. It depends on the devices that communicate with the AirTag having precise location. IF you have a phone in Russia, are your maps apps off by 50km these days?
