SK Telecom announced on the 22nd that 9.29 million subscribers have changed their SIM cards following a large-scale hacking incident involving SIM card information.

According to the newsroom, 100,000 customers changed their SIM cards the previous day, bringing the total to 9.29 million. SK Telecom has been offering free SIM card replacements since April 28.

SK Telecom has recently revamped its reservation system, allowing customers to choose not only the store they wish to visit but also their preferred date and time.

SK Telecom explained that even if a customer is unable to visit the store at the scheduled time after applying for a SIM card replacement, they can still replace it by visiting the designated store without needing to reapply.

If you wish to change the store where you applied for a SIM card replacement, you can check your reservation information on the T World SIM card replacement application page, click 'Cancel SIM card replacement application,' and then reapply.

SK Telecom stated that even if a reservation was made under the old system but the replacement could not be completed, customers can still replace their SIM cards by visiting the designated store without canceling the existing reservation.

There is no need to separately apply for SIM card replacements for additional devices such as tablets or watches. When applying for a free SIM card replacement, selecting 'Change all other lines and watches, tablets under your name' allows for a one-time change.
