WASHINGTON (WLS) – A leaked document from the Justice Department intended for law enforcement officials describes the length of time major cellphone companies retain sensitive customer data, including text message details and content.
Wired magazine reported that T-Mobile keeps a list of users’ text message recipients for up to five years and AT&T for up to seven years, according to the Department of Justice (DOJ) document dated August 2010.
Wired lists the retention periods of other carriers’ data, such as who keeps call detail records the longest (AT&T: up to seven years) and post-paid bill copies the longest (AT&T and Sprint: up to seven years).
Verizon Wireless is the only carrier that keeps text contents, although for three to five days.
