Telcos Sell Phone Location Data to Aggregators | Avast
An alarming investigative probe conducted by tech site Motherboard led to some shocking revelations. A Motherboard reporter stashed his phone somewhere in New York, then hired a bounty hunter to find it. The bounty hunter only needed the phone number and $300. Within minutes, he had the location pinpointed to a neighborhood in Queens, which was in fact where the reporter had hidden the phone. What was most surprising about this process is that the bounty hunter did not need to use any sort of hacking tool to find the phone. He simply used data purchased from telcos AT&T, Sprint, and T-Mobile.
