Korea's three mobile carriers will undergo a 45-day business suspension starting next week, as punishment for defying government warnings and providing illegal subsidies.
The Ministry of Science, ICT and Future Planning said Friday the mobile carriers will be banned from taking new subscriptions between March 13 and May 18th.
During that period, two carriers will suspended at the same time in rotation with the third.
Users will also be banned from changing their mobile device, unless it has been damaged, lost or used for over two years.
The ministry warned that it will take stronger measures, if the carriers do not comply.
Korea has three mobile carriers -- SK Telecom, KT and LG Uplus.
