For the August 2021 breach, you should have received a mailing from T-Mobile last September (at the earliest) informing you of what occurred.

How do I find out if I was affected???

How do I find out when I can get my settlement from the data breach

I was given a T-Mobile phone by a organization for.services provided and my information was compromised because of.the August 2021 breech. I never received notice because I am not the account holder. I have 3 sources which gave t-mobile as the cause. My DL and SS numbers are on the darkweb. What can I do?

more than likely you’ll need to go through the organization that provides you service through TMO.

They refuse to.speak with me and deny any responsibility.

Contact the organization that gave you the phone since they were the ones who was informed.
