The FCC found that AT&T’s location-based services program, which ran until March 2019, sold customer location information to aggregators that resold it to third parties without valid consent or reasonable safeguards. AT&T argued that location information is not protected customer proprietary network information, that it lacked fair notice, and that it acted reasonably.[13][14][14][14][13][14][14]
After paying the penalty, AT&T petitioned the U.S. Court of Appeals for the Fifth Circuit, which vacated the order on the ground that the FCC’s enforcement procedures denied a jury trial in violation of the Seventh Amendment. On June 4, 2026, the U.S. Supreme Court reversed the Fifth Circuit 8–1 and remanded, holding that FCC forfeiture orders do not themselves settle a party’s obligation to pay, that the government must bring a separate suit with a de novo jury trial to collect, and that the procedure therefore does not violate the Seventh Amendment; Justice Thomas dissented.[15][15][15][15][15][15][15]
July 2024Call Records of Nearly All Wireless Customers Copied

The U.S. Department of Justice twice determined that public disclosure could be delayed; AT&T said it had closed off the point of access and understood that at least one person had been apprehended.[16][16][16][16][16][16][16][16]
Earlier, in March 2024, AT&T said it was investigating a data set released on the dark web affecting about 7.6 million current and 65.4 million former account holders, which appeared to date from 2019 or earlier. AT&T agreed to settle class actions over the two incidents for $177 million, which a judge finally approved in October 2026; AT&T denied wrongdoing and said it settled to avoid the expense and uncertainty of protracted litigation.[17][17][17][17][17]
