Sprint this week became the last major US carrier to commit to ending its relationships with location aggregators, companies that resell phone location data, including real-time customer location. AT&T and T-Mobile last week pledged to cut off location aggregators in March, while Verizon has also told The Washington Post that it's working to end its location aggregator contracts. An investigation by Motherboard published last week found that loose regulation and oversight had led to location data being made available on an effective black market, with bounty hunters and other private citizens able to purchase real-time location data. Legitimate users of the data may be affected by the cutoffs, including roadside assistance services and banks that use customers' location to detect credit card fraud. Several members of congress have called for inquiries into the sharing and protection of location data.
