T-Mobile & Data Breach

T-Mobile Data Breach Class Action Lawsuit Overview: 

  • Who: Henry Thang filed a class action lawsuit against T-Mobile.
  • Why: T-Mobile wants a federal judge to pause the class action lawsuit filed against it in response to a massive data breach last month.
  • Where: The class action lawsuit is being heard in California federal court.

T-Mobile is asking a federal judge in California to pause a proposed class action lawsuit filed in response to a data breach that exposed the private information of millions of its customers last month. 

T-Mobile says it has been flooded with more than 30 class action lawsuits since the incident, and implored the court to pause the complaint until the U.S. Judicial Panel on Multidistrict Litigation (JPML) decides whether or not to group them together for multidistrict litigation. 

T-Mobile told the court that, without a stay, it would have to try and dismiss all the class action lawsuits separately using virtually the same argument each time, which would deplete its resources, the courts resources, and set the stage for inconsistent rulings. 

“In the absence of a stay, T-Mobile will be prejudiced because it would be required to expend significant resources litigating in multiple forums, conducting duplicative discovery and motion practice, and facing potentially inconsistent rulings on identical issues,” T-Mobile said. 

Further, T-Mobile told the court that the plaintiff in this particular class action lawsuit, Henry Thang, has  failed to identify any potential prejudice to himself or his proposed Class if a stay is granted. 

Thang has informed T-Mobile without explanation or reason that he will “oppose any motion seeking a stay,” says the company.

In August, T-Mobile reported that hackers breached the company’s systems and stole the personal and private information of more than 50 million of its customers, including their names, phone numbers, dates of birth, and social security numbers.

Affected customers included those who paid for service at the end of each month and those who applied for credit with T-Mobile, with 7.8 million of the former group facing the maximum amount of data exposed, according to the company.

T-Mobile argued that the cases will likely be consolidated, so it would be best to save everyone time and energy and put a pause on the class action lawsuits until the JPML makes its decision. 

“There is simply no reason for these courts to devote time, energy, and attention to these motions (or any other proceedings) when the JPML will likely consolidate and transfer all of those related actions into a single proceeding before a single judge for consolidated, pretrial purposes,” T-Mobile said.

    T-Mobile Customer. How do you know whether your personal data was included in the breach. T-Mobile argument that a customer can’t show/prove any harm or injury is basically BS. My bank said that often hackers or those who purchase the hacked data, may not use it for extended periods up to a few years. And b/c of that, his opinion was that settlement offers, which tend to include a specific period of credit monitoring or free LifeLock-type subscriptions are worthless and not sufficient to remedy past or future harm. He recommended other steps to attempt to protect your accounts & other personal data included in a breach. Also, breach occurred after T-Mobile takeover of Sprint. What about the data of Sprint customers now in the hands of T-Mobile?

    My information was breached and I called T-Mobile to discuss the issue after my husband had hundreds of dollars taken from his bank account and the T-Mobile agent told me that T-Mobile hadn’t had a data breach they were just warning customer that it might be one therefore they are giving a heads up. I have her ID number as well. She told me to change my PIN number. Which was really confusing to me since that wasn’t what my phone call was in reference to
