South Korea's telecom ministry said Wednesday it will seek a law revision to slap fines of up to 100 million won (US$96,311) on those using mobile phones under borrowed names, a practice used widely in crimes and illegal activities to evade investigation. The Ministry of Science, ICT and Future Planning said it hopes to establish legal grounds by June to punish any activities related to using or inducing, advertising, and mediating the use of such "pirate" phones, with possible penalties also including a prison term of up to three years.
