The big four mobile carriers face fines of between $12 million and $91 million each for selling their customers' real-time location data to third-party data brokers without customer consent, Federal Communications Commission Chairman Ajit Pai's office announced today.

These are "proposed" fines, meaning the carriers can dispute them and try to get them reduced or eliminated. The proposed fines are $91 million for T-Mobile, $57 million for AT&T, $48 million for Verizon, and $12 million for Sprint. That's a total of $208 million.
