Business & Human Rights Resource Centre invited Cricket (part of AT&T) to respond to the report by Access: "The Rise of Mobile Tracking Headers: How Telcos Around the World Are Threatening Your Privacy".  Cricket sent the following response:

"Thank you for your inquiry and the opportunity to respond.   Very simply put, Cricket does not use tracking headers.  We’ve verified this with our head of Networks and can confirm that we are not inserting tracking headers on our network. 

We agree consumer privacy is an important issue and we take the matter seriously at Cricket.  Customer care and satisfaction are incredibly important to us and we work hard – every day – to earn our customers business and their trust.  Again, thank you for the chance to respond."
