SK Telecom, which is currently implementing a free SIM card replacement service as a countermeasure against subscriber information hacking, announced on the 29th that it will apply a "SIM card format" to resolve the inventory shortage issue.
A representative from SK Telecom noted, "We are developing a SIM card software change method (SIM card format) to alleviate the inconvenience for roaming customers due to the SIM card inventory shortage."
After the occurrence of the SIM card information leak incident, SK Telecom encouraged customers to sign up for the SIM card protection service and began free SIM card replacements on the 28th. However, consumer complaints arose as users flocked to stores, leading to long waiting lines and a malfunctioning online reservation system.
The inventory of SIM cards this month is 1 million, and 5 million next month, which is insufficient to provide replacement services for a total of 25 million subscribers. In response, SK Telecom acknowledged the practical issue by stating, "There is a limit to the number of replacements we can do in a day."
"SIM card format" is a method that changes the SIM card software to achieve effects equivalent to replacement, and it minimizes inconveniences such as app rerouting and data backup, while reducing the time required. However, this also requires a system matching process after visiting the store.
Starting in mid-May, SK Telecom plans to extend the SIM card protection service to overseas roaming, and as of this date, the number of subscribers to the SIM card protection service has surpassed 10 million, with expectations to reach 15 million by early next month. The company stated that it would take 100% responsibility if any damage occurs after signing up for the SIM card protection service.
