BlockBeats News, March 30th — Law firm Greenberg Glusker announced today that it has won a $33 million arbitration award against telecom giant T-Mobile, calling this result a key milestone in holding the telecommunications operator accountable for SIM card swap-related cryptocurrency theft. According to Greenberg Glusker, the arbitration panel found T-Mobile liable for its "multiple security failures that enabled SIM card swap attacks to occur and resulted in cryptocurrency theft."

The final amount, including over $6.5 million in attorney's fees, interest, and costs, has been fully paid by T-Mobile. Greenberg Glusker has filed a petition with the Los Angeles Superior Court to confirm the award and make the details of the case public. The law firm emphasized the scale and significance of this outcome. Greenberg Glusker attorney Pierce O’Donnell, who led the cross-examination during arbitration, stated: "This is the largest known SIM card swap-related award and a significant victory for cellphone consumers."

The firm underscored that its litigation team — composed of O’Donnell, Paul Blechner, James Molen, and Eric Sefton — demonstrated T-Mobile's long-standing failure to address known security vulnerabilities.

Blechner, while examining key witnesses including the perpetrators of SIM card swap attacks, said: "This is a great result for our client and cellphone users worldwide. For years, SIM card swap has been an uncontrolled security vulnerability. Operators like T-Mobile have long known about this issue but failed to take basic preventive measures. This ruling indicates that they must do better."
