• The Ministry of Science and ICT lifted its administrative guidance after SK Telecom rebuilt its USIM stockpile and demonstrated a stable reservation system.
• In response to the April data breach, SK Telecom launched a free USIM replacement program on April 25 that has issued new cards to 9.29 million subscribers to prevent identity theft and fraud.
