Is Your Wireless Carrier Tracking Your Surfing Habits (Maybe)
Oh what your mobile phone carrier knows and tracks about you! A one-page document from the Justice Department‘s cybercrime division shows how cell phone companies record and retain your call and surfing activity (calls, text messages, web surfing and approximate location). Here’s a summary of how each company retains your information (full details in the image below):
- Verizon Wireless – rolling one-year records of cell tower usage & what phone accessed what web site
- AT&T / Cingular – ongoing records of cell tower usage since July of 2008
- T-Mobile USA – doesn’t keep any data on Web browsing activity
- Sprint Nextel’s Virgin Mobile – 3 month record of text content
- Other than Virgin Mobile and Verizon, none of the carriers keep texts but they keep records of who visited a particular web site.
- Verizon keeps some information for up to a year that can be used to ascertain if a particular phone visited a particular Web site
