SK Telecom: ”17.21 million people signed up for USIM protection... 935,000 people to exchange USIM cards”

SK Telecom (017670) announced that as of 3 p.m. on May 3, the number of subscribers to the USIM protection service, which is being implemented in response to the USIM information leak incident, had reached a total of 17.21 million.
This means that 1.37 million people signed up in just one day. SK Telecom has been gradually implementing automatic subscriptions to its USIM protection service since the 2nd, and is offering the service to approximately 8 million people who have not yet signed up.
The plan is to automatically enroll up to 1.2 million people per day by May 14. In particular, priority is being given to elderly people aged 75 and over and people with disabilities.
The USIM protection service is a security technology that combines USIM information with mobile phone terminal information and blocks the use of the USIM from devices other than the registered terminal.
This will prevent hackers from illegally duplicating USIM cards and using them on other devices, thus preventing so-called "SIM swapping."
The Ministry of Science and ICT announced the results of its initial investigation on April 29.
However, "The IMEI number of the mobile phone was not leaked in this incident, and if you subscribe to the USIM protection service, it is not possible to illegally copy and use the USIM with only the leaked information.
Meanwhile, as of 3 p.m. on the same day, the total number of physical USIM card exchanges reached 935,000, meaning that 35,000 people had exchanged their USIM cards in just one day.
