Can someone explain this to me? It nailed me, and i'm roaming far from home.
I'm rusty on my phone tracking technology... they send the phone an SMS, is that the mechanism? (e.g., premium sms processing gatway has geo?) Or do they tap into a telco celltower lookup?
I can think of a couple fun commercial applications.
- freehunter 15y agoI don't know all the details of it, but it doesn't use your phone for anything but a place to bounce the signal. It pings your phone, then measures the time it takes to receive a signal from the towers nearest to it (at least two, preferably three or more). This is all done on the end of the carrier. The text they send you just verifies this is the phone they are looking for and gains your permission.
