1) SIGN-UP FEES

     In the second quarter of 2004, sign-up fees increased 29% compared to the
     second quarter of 2003 (hereinafter referred to as "on a YoY basis") and 7%
     compared to the first quarter of 2004 (hereinafter referred to as "on a QoQ
     basis") due to an increase in the number of new subscribers.

2) MONTHLY FEES

     The YoY and QoQ increases in monthly fees were due to an increase in the
     number of total subscribers.

3) CALL CHARGES

     The YoY decrease in the call charges was caused by contract-based discount
     plans and a decrease in the minutes of usage ("MOU"). The QoQ decrease was
     smaller despite the contract-based discount plans because of a higher MOU
     on a QoQ basis.

4) VALUE ADDED SERVICES ("VAS") AND OTHERS

     VAS and other sales have decreased on a YoY basis primarily due to caller
     ID tariff cuts implemented in October 2003. The QoQ sales increased,
     however, because of a higher demand for VAS such as "color rings" and
     automatic roaming services.

5) WIRELESS INTERNET SALES

     The YoY and QoQ revenue growths from wireless Internet sales were driven by
     higher wireless Internet usage primarily resulting from the continuous
     introduction of high-end handsets and the introduction and development of a
     variety of multimedia services. Consequently, the wireless Internet sales
     accounted for 19% of the cellular service revenues in the second quarter.

6) INTERCONNECTION REVENUES

     The new interconnection rates introduced by the Ministry of Information and
     Communication were applied retroactively from the beginning of the second
     quarter, resulting in the QoQ and YoY decreases in the interconnection
     revenues.

     * Applying the new interconnection rates retroactively from the beginning
     of the first quarter would result in a decrease of KRW 26.4 billion in the
     interconnection revenues for the first quarter. For details please refer to
     Appendix C.

1)   Includes R&D expenses related depreciation.

2)   For details, please refer to non-consolidated statements of income in
     Appendix A.


1) LABOR COSTS

     Labor costs have increased YoY due to the factors including an increase in
     regular wages. Labor costs have decreased QoQ, however, because incentive
     bonus payments were made in the first quarter.

2) COMMISSIONS PAID

   -Marketing commissions

     Because other mobile telecommunications service providers were given the
     first opportunity to attract subscribers under the mobile number
     portability ("MNP") regulations due to SKT's dominant market position, SKT
     made a strategic decision to lock in its subscribers and maintain its
     position as the market leader until the MNP policy became available to SKT
     as well. Marketing commissions increased due to the diversification of
     distribution channels, the enhancement of handset upgrades program and the
     expansion of membership program.

   -Other commissions

     The costs paid to content providers increased due to the growth in the
     information usage revenues related to wireless Internet services. SKT also
     expanded its market research in the second quarter in order to prepare
     itself for the MNP also becoming available to SKT, causing the related
     costs to increase. The roaming fees increased as well.

3) DEPRECIATION

     The YoY increase was due to the amortization of WCDMA frequency usage right
     (KRW 23.9 billion/quarter) from December 2003. The QoQ increase resulted
     from an increase in the depreciable assets.

4) NETWORK INTERCONNECTION EXPENSES

     The mobile to mobile interconnection costs increased in the second quarter
     due to the interconnection rates adjustment. The YoY mobile to land
     interconnection costs decreased because we made a payment to Korea Telecom
     of KRW 40.6 billion for its 114 directory information service in the second
     quarter of 2003.

5) LEASED LINES

     Leased line expenses increased QoQ and YoY because additional lines were
     leased to accommodate the subscriber growth and increased wireless Internet
     traffic and to enhance the call quality.

1)   For details, please refer to non-consolidated statements of income in
     Appendix A.


1) INTEREST INCOME

     The YoY and QoQ decrease in the interest income was due to a decrease in
     the average balance.

2) INTEREST EXPENSE

     The interest expense decreased on a YoY basis due to lower costs of
     borrowing and a decrease in the average balance of interest-bearing debt.
     The interest expense increased on a QoQ basis, however, because of an
     increase in the average balance of interest-bearing debt.

3) EQUITY METHOD PROFITS

     The increase in the equity method profits was due to the profit improvement
     in our subsidiaries such as SK Communications.

4) OTHERS

     The decline in other non-operating income was primarily caused by the
     dividend income from the second quarter of 2003 and the first quarter of
     2004 (KRW 25.7 billion from Korea Telecom and KRW 17.4 billion from POSCO
     respectively).

     Other non-operating expenses have increased on a QoQ basis due to the
     impairment loss in long-term investment securities (KRW 11.8 billion)
     caused by Enterprise Networks' application for court receivership.

1)   Debt/Equity Ratio = Interest-bearing debt / Shareholders' equity

     * Interest-bearing debt = Short-term borrowings + Current portion of
       long-term debt + Long-term borrowings & corporate bonds


1) CURRENT ASSETS

     The balance as of June 2004 is lower because the cash and marketable
     securities for June 2003 included the fund for 3% buyback and cancellation
     of shares (from June 30 to August 11, KRW 524.4 billion).

2) INVESTMENT ASSETS

     A 43% increase in the investment assets on a YoY basis resulted from the
     purchase of POSCO shares (KRW 332.5 billion) in July 2003.

3) TOTAL LIABILITIES

     The amount of long-term debts has increased due to the issuance of bonds
     such as exchangeable bonds based on treasury shares (KRW 385.9 billion) and
     Global Bond (US $300 million), whereas the amount of short-term borrowings
     has decreased due to the repayment of maturing debt.

4) TOTAL SHAREHOLDERS' EQUITY

     An increase in the shareholder's equity was due to an increase in the net
     income as of June 2004.
