Information Commissioner’s Office in the U.K. says it has been approached by an unnamed mobile phone service provider with information about employees believed to be selling customer data. The data included mobile phone contract information and expiration dates. T-Mobile said it alerted the ICO when it learned that contract renewal information was being passed to third parties without its knowledge. The company said it was “surprised” that its name had been publicly reported because it had been previously asked to keep all information confidential to avoid hindering judicial proceedings.”]
