LG Uplus introduced a new security system in April this year that applies random numbers to the IMSI system.
LG Uplus has been carrying out USIM updates and free replacements as it pushes ahead with the new security system.
As of the 20th, the cumulative number of customers who had completed a USIM update or replacement stood at about 6.589 million.
The completion rate as of the 20th was 38.4%.
LG Uplus will sequentially begin automatic updates for USIM (USIM/eSIM) starting on the 22nd for eligible customers among those who have not yet completed the process. The rollout includes MVNO and eSIM users, and aims to apply the strengthened security system without requiring store visits or separate action.
Eligible users for the automatic update include individual customers, including minors and foreigners, corporate customers, MVNO users, and eSIM users. However, customers staying overseas are unable to use domestic telecom networks, so even if they are included among the eligible users, the automatic update will not actually be carried out.
Automatic updates will run on weekdays from 10 a.m. to 5 p.m. If any inconvenience arises during the update process, customers can receive immediate support through a 24-hour free USIM counseling center (080-864-1010), and a KakaoTalk counseling channel will also be available.
Dedicated counters will be operated at 1,709 stores nationwide. In addition, the company plans to run its enterprise-wide customer care situation room to monitor update progress in real time and quickly detect, analyze and respond to any signs of abnormalities.
IMSI serves to identify users when a device connects to a network. It consists of a country code, operator code and subscriber code, and is stored in the USIM and the telecom carrier's servers along with the Ki value for authentication purposes.
A security vulnerability in IMSI was identified, and the revised system was applied in April.
LG Uplus carried out an internal inspection following last year's telecom personal information breach and found a security vulnerability in which random numbers had not been applied to the subscriber identification number (IMSI). Accordingly, it began designing a new IMSI system in June last year and, after commercial verification, sequentially applied the new IMSI system starting on April 13 this year.
LG Uplus is automatically applying the revised system to number-porting customers after April 13, and it is also automatically applying the new USIM's revised system to new customers after April 13. Separately, it is providing prior individual notice of the scheduled automatic update date to eligible customers.
Notices about automatic updates are being delivered through the U+one app, website, stores and SNS channels. Advance notices to individual customers have been under way since the 8th, with messages sent at least three times: two weeks before the scheduled date, one week before and one day before, via text messages and KakaoTalk notification messages.
Customers who do not want the automatic update or who cannot complete it on the scheduled date can choose to defer the update. Deferral requests can be made through a notice text message, the U+one app, the website or the USIM counseling center. If a deferral is requested, the automatic update schedule will be postponed until the end of the year, and the application channel for corporate customers is the USIM counseling center. Deferrals can be canceled at any time.
The manual USIM update process, which has been under way since April, will continue. Free replacements that began in April will also continue. Manual updates can be done through notice text messages, the U+one app and the website. Free USIM replacement is also available by visiting a store.
Customers who are not eligible for the automatic update include users of additional devices such as smartwatches and some tablets, users of older USIMs, and lines subscribed to call forwarding and data blocking services. These customers can receive a free USIM replacement when they visit a store.
To improve accessibility for customers without stores nearby or those who have difficulty using digital services, the company plans to prepare multiple alternative channels. It plans to operate temporary hub stores using retailers and other locations for customers in areas without stores, with remote island and mountainous regions cited as examples of such areas. It also plans to support digitally vulnerable groups, including older adults, and to run on-site services using parcel delivery and mobile store services using vehicles.
