Following press investigations and congressional concern about leaks and improper use of consumer location data provided by mobile network operators, the national carriers have said that they will stop or strictly limit aggregators’ access to such information.  

Verizon, AT&T and Sprint have all said that they will start strictly limiting third-party aggregators’ access to network-based location information, and T-Mobile US CEO John Legere tweeted that his company will “not sell customer location data to shady middlemen.”
