NON-CONSOLIDATED FINANCIAL INFORMATION AS OF AND FOR THE SIX MONTHS ENDED JUNE
30, 2002 AND 2003

     We must file semi-annual reports with the Financial Supervisory Commission
of Korea and the Korea Stock Exchange. SK Telecom's unaudited, reviewed and
non-consolidated financial information as of and for the six months ended June
30, 2002 and 2003 shown below were prepared pursuant to generally accepted
accounting principles in Korea ("Korean GAAP"), which differs in certain
material respects from generally accepted accounting principles in the United
States.

     The financial information below is non-consolidated and does not include
the results of operations of our subsidiaries except for certain subsidiaries
which are accounted for using the equity method of accounting of Korean GAAP.
Therefore, our income statement, including revenues and net income, as well as
our balance sheets, including total assets and total liabilities, if prepared on
a consolidated basis, may be significantly different from those in SK Telecom's
non-consolidated financial statements. See note 2(b) of our notes to
consolidated financial statements for a list of our subsidiaries that were
included in our consolidated financial statements in the last three years which
is available in SK Telecom's annual report for 2002 filed under Form 20-F, as
amended. Under Korean GAAP, for the years ended December 31, 2000, 2001 and
2002, SK Telecom's non-consolidated revenues accounted for 77.6%, 74.4% and
92.6%, respectively, of our consolidated revenues. We can give no assurance as
to what the actual ratios will be for 2003. In addition, SK Telecom's results of
operations for the first six months of 2003 may not be indicative of results of
operations for the full year 2003.

     Shinsegi was merged into SK Telecom on January 13, 2002. As a result, our
results of operations from that date include the results of operations of the
business that was previously operated by Shinsegi, as a subsidiary, and which
was accounted for using the equity method of accounting in our non-consolidated
financial information.

     Non-Consolidated Operating Income. SK Telecom's operating income increased
by 14.6% to Won 1,567.8 billion for the six months ended June 30, 2003 from Won
1,368.5 billion for the six months ended June 30, 2002, as a result of a greater
increase in operating revenue than the increase in operating expense, for the
six months ended June 30, 2003 as compared to the six months ended June 30,
2002.

     Non-Consolidated Operating Revenue. SK Telecom's operating revenue
increased by 14.5% to Won 4,629.6 billion for the six months ended June 30, 2003
from Won 4,044.8 billion for the six months ended June 30, 2002, principally
reflecting a 16.9% increase in cellular revenue to Won 4,108.9 billion for the
six months ended June 30, 2003 from Won 3,514.6 billion for the six months ended
June 30, 2002, which was offset by a 1.8% decrease in interconnection revenue.

     The increase in SK Telecom's cellular revenue was principally due to an
increase in the number of SK Telecom's average wireless subscribers and
non-consolidated average monthly revenue per subscriber (excluding
interconnection revenue). The number of

                                       6

SK Telecom's subscribers increased to approximately 17.9 million as of June 30,
2003 from approximately 16.5 million as of June 30, 2002. SK Telecom's
non-consolidated average monthly revenue per subscriber (excluding
interconnection revenue) increased by 5.6% to Won 38,942 for the six months
ended June 30, 2003 from Won 36,890 for the six months ended June 30, 2002. The
increase was principally due to increases in average monthly revenue from
wireless Internet sales and average monthly revenue from value-added services
and other sales. However, the increase in cellular revenue was partially offset
by a reduction in tariffs of 7.3% (based on the reduction in a standard tariff
plan) from January 2003.

     Average monthly revenue from wireless Interest sales increased by 74.7% to
Won 5,408 for the six months ended June 30, 2003 from Won 3,096 for the six
months ended June 30, 2002. Wireless Internet sales increased by 98.8% to Won
570.7 billion for the six months ended June 30, 2003 from Won 287.1 billion for
the six months ended June 30, 2002, representing 12.3% of SK Telecom's cellular
revenue, primarily due to the increased number of wireless Internet-enabled
handset holders. However, the increase in wireless Internet sales was partially
offset by a change in the method SK Telecom uses to account for wireless
Internet sales. SK Telecom now recognizes e-lottery sales net of the sourcing
cost of content. Such sales were previously recognized on a gross basis.

     Average monthly revenue from value-added services and other sales increased
by 24.4% to Won 2,091 for the six months ended June 30, 2003 from Won 1,681 for
the six months ended June 30, 2002. Value-added services and other sales
increased by 45.0% to Won 220.6 billion for the six months ended June 30, 2003
from Won 152.1 billion for the six months ended June 30, 2002, despite a change
in the accounting method related to voice information services. SK Telecom now
recognizes voice information sales net of commissions to contents providers.
Such sales were previously recognized on a gross basis.

     Interconnection revenue decreased by 1.8% to Won 520.7 billion for the six
months ended June 30, 2003 from Won 530.1 billion for the six months ended June
30, 2002. The decrease was due to a reduction in land-to-mobile interconnection
rates beginning April of 2003 to account for a decrease in the use of land lines
owned by us by land-line callers calling a subscriber, partially offset by an
increase in mobile-to-mobile interconnection rates due to an increase in minutes
of use.

     Non-Consolidated Operating Expense. SK Telecom's operating expenses for the
six months ended June 30, 2003 increased by 14.4% to Won 3,061.8 billion
compared to

                                       7

Won 2,676.3 billion for the six months ended June 30, 2002. The increase in SK
Telecom's operating expenses was primarily due to the increases in commissions,
interconnection, depreciation, labor, leased line and miscellaneous operating
expenses.

     Commissions paid to SK Telecom's authorized dealers increased by 21.2% to
Won 1,082.7 billion for the six months ended June 30, 2003 compared to Won 893.1
billion for the six months ended June 30, 2002. The increase was primarily due
to the increase in average subscribers by 11% during the period and increase in
the number of handsets sold, and our aggressive marketing activities to maintain
our market leadership in 2G & 2.5G services as well as 3G services going
forward. SK Telecom also incurred an increase in consulting fees paid in
relation to the establishment of a corporate innovation strategy.

     Interconnection expenses increased by 21.5% to Won 417.1 billion for the
six months ended June 30, 2003 compared to Won 343.4 billion for the six months
ended June 30, 2002. The increase was primarily due to the higher subscriber
numbers and an increase of the mandated payment in Universal Service Obligation
fund, which is a fund into which certain telecommunications service providers in
Korea contribute based upon such company's net annual income (which is
calculated pursuant to guidelines set forth by the Minister of Information
Communication which differ from SK Telecom's accounting practices) to fund the
provision of telecommunication services to the general public, for the first
quarter of 2003 of Won 22.5 billion compared to Won 7.2 billion in the first
quarter of 2002, which were only partially offset by a decrease in
interconnection rates and a decrease in the level of interconnection fees that
SK Telecom must pay to other operators for calls using their networks.
Additionally, SK Telecom reflected as an expense in the second quarter of 2003
all amounts due to be paid to KT Corp. for the years 1998, 1999, 2000 and 2001
pursuant to a cost sharing arrangement regarding the provision of directory
assistance services by KT Corp. to SK Telecom's subscribers. SK Telecom's share
of expenses for the provision of directory assistance service by KT Corp. SK
Telecom will discuss with KT Corp. the amounts to be paid by SK Telecom for
directory assistance services provided to its subscribers during 2002 and the
six months ended June 30, 2003.

     Depreciation and amortization expenses increased by 6.1% to Won 661.9
billion for the six months ended June 30, 2003 compared to Won 623.9 billion for
the six months ended June 30, 2002. The increase in depreciation expenses was
primarily due to the expansion of SK Telecom's CDMA 1xRTT network.

                                       8

     Labor cost increased by 17.8% to Won 192.9 billion for the six months ended
June 30, 2003 compared to Won 163.7 billion for the six months ended June 30,
2002. The increase was primarily due to payment of performance bonuses to its
employees in 2003 in respect of SK Telecom's performance in 2002.

     Leased line expenses increased by 9.0% to Won 149.3 billion for the six
months ended June 30, 2003 compared to Won 136.9 billion for the six months
ended June 30, 2002, primarily due to an increase leased line expenses in
response to higher wireless traffic.

     Miscellaneous operating expenses increased by 10.9% to Won 374.0 billion
for the six months ended June 30, 2003 compared to Won 337.3 billion for the six
months ended June 30, 2002, primarily due to increases in research and
development expenses and maintenance expenses.

     Non-Consolidated Other Income. Other income increased by 2.8% to Won 142.5
billion for the six months ended June 30, 2003 compared to Won 138.6 billion for
the six months ended June 30, 2002. Other income consists primarily of incoming
fees, interest income, foreign exchange and translation gains, gain on equity
method, gain on disposal of property and equipment, reversal of allowance for
doubtful accounts and miscellaneous income. Other income increased primarily due
to an increase in incoming fees (6.6% increase to Won 50.3 billion for the six
months ended June 30, 2003 compared to Won 47.2 billion for the six months ended
June 30, 2002) which was principally due to an increase in rental income from
rentals of mobile phones and an increase in service income from the provision of
services relating to testing of 3G related technology for SK IMT Co., Ltd. and
miscellaneous income (665.3% increase to Won 57.4 billion for the six months
ended June 30, 2003 compared to Won 7.5 billion for the six months ended June
30, 2002), which partially due to an increase in income from sale of tangible
and intangible property, which were partially offset by the absence of gain on
equity method (compared to Won 25.7 billion for the six months ended June 30,
2002) which was partially due to losses at SK Communications Co., Ltd. and a
decrease in foreign exchange translation gains (93.2% decrease to Won 2.3
billion for the six months ended June 30, 2003 compared to Won 33.9 billion for
the six months ended June 30, 2002).

     Non-Consolidated Other Expenses. Other expenses increased by 37.8% to Won
280.8 billion for the six months ended June 30, 2003 compared to Won 203.8
billion for the six months ended June 30, 2002. Other expenses consists
primarily of interest expense, donations, foreign exchange and translation
losses, loss on equity method and

                                       9

miscellaneous expenses. Other expenses increased primarily as a result of
increases in interest expenses, loss on equity method and miscellaneous
expenses. As a percentage of operating revenue, other expenses increased
slightly to 6.1% for the six months ended June 30, 2003 from 5.0% for the six
months ended June 30, 2002.

     Non-Consolidated Income Tax. Provision for income taxes increased by 7.9%
to Won 430.3 billion for the six months ended June 30, 2003 from Won 398.7
billion for the six months ended June 30, 2002.

     Non-Consolidated Net Income. Principally as a result of the factors
discussed above, SK Telecom's net income increased by 10.5% to 999.2 billion for
the six months ended June 30, 2003 from Won 904.6 billion for the six months
ended June 30, 2002.
