LocationSmart

An anonymous reader quotes a report from Ars Technica:Until 2019, the ruling said Verizon operated a location-based services program that sold customer location data through intermediaries like LocationSmart and Zumigo, who then resold it to dozens of third-party entities.

This week, the U.S. District Court of Appeals for the District of Columbia has sided with the Federal Communications Commission (FCC), upholding a fine against T-Mobile for illegally selling customer location information (CLI). The ruling relates to an FCC decision last year, which saw the regulator issue fines totalling almost $200 million to T-Mobile, AT&T, and Verizon for sharing customer data to ‘aggregators’ without prior consent.
