Three of those workers have pleaded guilty so far.

Fahd was arrested in Hong Kong in February 2018, but was only extradited to the US on August 2nd, 2019. He's facing five charges related to wire fraud, five charges related to Travel Act violations, conspiracy to violate the Computer Fraud and Abuse act and four counts linked to accessing and damaging protected computers.

This isn't the first time perpetrators have had inside help from carrier employees, but it may be one of the largest. Fahd reportedly got "millions of devices" off AT&T service, and made millions of dollars in profit in the process. Federal prosuecutors likely want to send a message to others who would try similar schemes.
