A member of the phone fraud that helped tamper with the phone number... "I'm guilty even if I didn't know about the crime."

The Supreme Court ruled that if you helped a phone fraud organization to tamper with your mobile phone's calling number, you should be punished as a communication medium even if you didn't know it was used for fraud.

The Supreme Court overturned the original ruling that acquitted Kim, in his 50s, of fraud and violating the Telecommunications Business Act, and returned the case to the Daegu District Court.

Kim was indicted in March last year on charges of helping members contact victims by inserting a USIM into a specific number of a repeater at the direction of a member of a telephone fraud at an examination center in Daegu.

The courts of the first and second trials all acquitted Kim, saying he did not appear to have recognized that the repeaters or USIMs he installed were used for crimes.

However, the Supreme Court saw that Kim's prosecution of "intermediation of other people's communications under the Telecommunications Business Act" only needs to know that individuals connect communications between others, and there is no need to recognize that they are used for crimes.

In addition, Kim has received and managed communication repeaters from members of the organization and has 51 USIMs at the time of his arrest, so he judged that his intention to violate the Telecommunications Business Act was recognized.
