What your mobile phone will reveal
The following information comes from a Department of Justice document name “Retention Periods of Major Cellular Service Providers,” and is marked “Law Enforcement Use Only.” Here’s what they prefer the public not know:
Verizon keeps a list of everyone you’ve exchanged text messages with for the past year. Sprint keeps the list for 18 months, T-Mobile for up to five years, and it’s seven years for AT&T. That makes Verizon appear to have the most privacy-friendly policy, right? Not quite—Verizon retains the actual contents of text messages for five days.
