Govt seeks remote update after lawmakers warn of LGU+ subscriber number exposure risk

South Korea's government is pursuing automatic remote updates alongside USIM replacements after concerns that LGU+'s International Mobile Subscriber Identity (IMSI) directly contains subscriber phone numbers, raising privacy exposure risks. Lawmaker Cho Kyung-tae said LGU+ differs from SK Telecom and KT in how it generates IMSI and said only about 30 percent of users have replaced USIM cards. Vice Prime Minister Bae Kyung-hoon said the remote update is due to start on Oct. 20.
