A user sued T-Mobile after his SIM card was attacked, which resulted in losses of more than 450 thousand dollars in Bitcoin.

The user who filed this lawsuit is Mr. Calvin Cheng who lost 15 bitcoins.

Calvin says he lost his money after interacting with Brandon Buchanan, who is also a user and customer of T-Mobile and co-founder of Iterative Capital.

Cheng, who resides in California, received a message via “Telegram” that he believes to be from “Buchanan” offering him a price higher than the market value of 15 Bitcoin in May 2020.

Shortly afterwards, Chang’s account was hacked and SIM swapped and no further details were revealed about the mechanism by which the attack was carried out.

Tell Cheng’s lawyers said that the systematic and repeated failures of T-Mobile have become very frequent in the recent period, as the company failed more than once to protect sensitive information of customers, so the SIM card attacks are responsible for them.

The complaint, filed Monday in the Southern District of New York, alleges that T-Mobile violated federal laws and neglected proper verification before hiring and training competent and reliable customer service personnel.

T-Mobile has responded that it maintains the highest standards of authentication procedures to protect its customers against SIM fraud.
In a similar incident, cryptocurrency investor Michael Terpin sued AT&T after losing $23.8 million in cryptocurrency in 2018.
