According to a letter from the US Federal Communications Commission to SK Telecom, if the company does not take immediate action to stop fraudulent phone callers posing as Walmart employees, they may be cut off from the US communications network. An industry traceability team authorized by the US Federal Communications Commission traced the origin of 29 automated voice calls within three months and has requested SK Telecom to investigate these calls, but the company never responded. The letter also mentioned that SK Telecom needs to effectively mitigate the problem of illegal traffic within 48 hours and take measures to prevent such problems from happening again within 14 days.
