UPDATE: Shortly after publishing our original story below, T-Mobile’s media relations department has reached out to share a very encouraging number highlighting the relatively small scale (in the grand scheme of things) of this newly revealed security breach.
That’s not nothing, mind you, given that said customer base recently jumped over the 100-million mark, possibly equating to around 200,000 people across the nation. But it’s also not a debacle in any way similar to the absolutely massive network outage from last summer.
Compared to so many other companies and businesses, not to mention most regular people, T-Mobile has had a pretty solid year, overcoming numerous legal, logistical, and technological obstacles in 2020 to close a vital merger, surpass AT&T’s subscriber figures, and expand its industry-leading 5G network at an objectively insane pace.

Instead, all that an unnamed group of hackers was able to obtain is “customer proprietary network information (CPNI) as defined by the Federal Communications Commission (FCC) rules.” That may include phone numbers, as well as the number of lines associated to certain accounts, and in “some cases”, call-related information gathered “as part of the normal operation of your wireless service.”
All that being said, you should keep in mind that those who haven’t received a security alert text from T-Mo in the last 24 hours or so were most likely never affected by the data breach in the first place, which is said to have gone down at some point last month.
