The following information was not accessed:

Same as others, $56.54 received in PayPal from this data breach. Honestly had forgotten about it, being over two years ago and all.

I was slammed over to T-Mobile from Sprint 3 months ago. My bill went up by $20/mo because their system supposedly couldn’t handle one of my Sprint discounts (total lie that bills wouldn’t change), and now when I log in I see my data was stolen. Garbage company. Total crap.

I just received mail a few months ago with class settlement info, for application years ago. Switched to T-Mobile in September 2022, and notified with banner that I’m included in this one. Thankfully I keep credit frozen. It’s fools like these that keep it frozen.Time to give them a multi-billion dollar fine they won’t soon forget. Along with making executives financially responsible. Bar would be too high to prove criminal responsibility.

tmo is constantly hacked for data breaches. What kind of security platform have they built?

So a third of their subscribers were affected. Are they planning on notifying those that were affected or should we assume that we were? And they weren’t clear if it was only current subscribers.

Judging by some comments about getting more spam calls, I’ll hold out a tiny hope that I wasn’t one of the affected ones as my spam calls have decreased every month. But I’m sure it’s false hope 🙁

I think affected customers will see a banner at the top when logging in on the app or browser, and it would also mention it in a future statement.

I’m not sure if subscribers means number of lines or number of accounts. Hard to believe there are 100mil+ accounts, so I’m going to assume that’s total lines. With 37 million accounts affected, I’m going to say that’s about all accounts, which comes out to roughly 3 lines subscribers/lines per account.

I was notified by snail mail. I don’t even have an account with them. I checked their cell plans and phone prices at a physical location about 10 years ago, or so. So now we all know that they NEVER get rid of your data!
Edit: I just realized this is a NEW Breech! I was commenting on the Last One! Sorry.
