How long does TMobile store usage data and what is included? [closed]
TMobile is widely used as a mobile provider, and it is the third largest in the United States. I know they store usage data, also referred to as CDRs or Call Detail Records.
I would like to know what conclusions an attacker might be able to draw from just the usage data, specifically taking into account how long the data is stored (so how long of a timeline of a person's activities can be constructed.
I did some research and the closest I came to was a chart on https://www.aclu.org/cell-phone-location-tracking-request-response-cell-phone-company-data-retention-chart
However, this is from 2010, so is probably outdated.
What specifically can an attacker get or do with a person's TMobile usage logs?
