FOR RELEASE: IMMEDIATE

U.S. CELLULAR REPORTS FOURTH QUARTER RESULTS

Feb. 4, 2004, Chicago, Illinois — United States Cellular Corporation [AMEX:USM] reported service revenues of $620.6 million for the fourth quarter of 2003, up 8% from $575.4 million in the comparable period a year ago. The company recorded operating income of $24.3 million during the quarter, a decrease of $13.2 million, or 35%, from the fourth quarter of 2002. Operating expenses include a $22.3 million loss, primarily related to the assets to be sold to AT&T Wireless Services, Inc. [NYSE:AWE] (“AT&T Wireless”) pursuant to the transaction announced in November 2003. The company recorded a net tax benefit in the quarter of $0.5 million, primarily due to the benefits of net operating losses, including losses related to the sale of the South Texas markets. Net income and basic earnings per share were $20.6 million and $.24, respectively compared to $14.6 million and $.17, respectively, in the comparable period one year ago. In the fourth quarter of 2002, the company recorded $16.5 million of pre-tax losses ($15.9 million net of $0.6 million of taxes) related to the writedown in value of certain investments.

The company’s operating results include operations, through July 31, 2003, of the markets that were part of an exchange of assets with AT&T Wireless that occurred in August 2003. The company’s operating results include, and will continue to include through the transaction closing date, the operations of the markets that will be sold to AT&T Wireless pursuant to the transaction announced in November 2003.

Fourth Quarter Highlights

• Customer units totaled 4,409,000, a 7% increase from 4,103,000 customers one year earlier.
   
• Net customer unit activations from distribution channels totaled 141,000 during the quarter, compared to 160,000 activations for the same quarter of 2002. Fourth quarter 2003 activity reflects the writeoff of 16,000 prepaid customers and 10,000 postpay customers based on a review of certain accounts. The 10,000 postpay customer writeoffs are included in the fourth quarter postpay churn calculation.

• For the quarter, the company recorded postpay churn of 1.4%, which is favorable to industry averages and which is the company's lowest quarterly postpay churn rate since it began tracking the measure.
   
• Average monthly retail service revenue per customer increased 3% year-over-year in the quarter to $39.68, compared to $38.69 in the same period a year ago.

“2003 was a year of many successes and accomplishments for U.S. Cellular, and we capped the year with a quarter of very strong operating results,” said John E. Rooney, president and chief executive officer. “Retail service revenue per customer, or that portion of service revenues that we can most influence, was up for the eighth quarter in a row on a year to year basis. Service revenues increased 8% for the fourth quarter, on a year-over-year basis, and operating profitability, before a loss on assets held for sale, improved as well for the same period.

“All of us at U.S. Cellular are committed to satisfying customers. That’s the cornerstone of our dynamic organization, and it’s reflected in the focus of our associates on delivering exceptional customer service, whether through contact with our customers or the exceptional wireless service our upgraded networks provide. It was this focus on customer satisfaction that resulted in a 1.4% post pay churn rate in the quarter. This performance would be exceptional under any circumstance – it’s one of the best rates in the industry – but it is even more impressive given the highly competitive nature of our industry, which was made even more challenging this quarter with the introduction of wireless local number portability. Our emphasis on customer satisfaction is paying off: Most of our customers are staying, and we’re welcoming those from other carriers. We’ve had a net gain in customers from number portability since the FCC local number portability mandate took effect November 24.”

Accounting Matters

During the quarter, U.S. Cellular included in operating expenses a pre-tax loss of $22.3 million ($9.3 million net of $13 million of taxes), primarily related to the difference between the fair value and book value of the assets being sold to AT&T Wireless in the transaction announced in November 2003.

Also during the quarter, U.S. Cellular identified an impairment related to one of its minority investments, recording a $1.7 million pre-tax loss on investments for the period ($1.5 million net of $0.2 million of taxes) to reduce the investment to its fair value.

SFAS No. 143

U.S. Cellular adopted Statement of Financial Accounting Standards (“SFAS”) No. 143, “Accounting for Asset Retirement Obligations,” effective Jan. 1, 2003. An asset retirement obligation is the cost of closing facilities and removing assets, or performing other remediation to a property as required by contractual agreement. This accounting principle requires entities to record the estimated fair value of a legal liability for an asset retirement obligation in the period it is incurred. Adoption of this standard in the first quarter of 2003 required U.S. Cellular to recognize estimated liabilities related to the future remediation of certain leased properties.

During the fourth quarter of 2003, the company revised the probability that leased cell sites would require remediation and determined that an additional remediation liability was required. As a result of this change, the company has restated its first-quarter 2003 financial statements to reflect a liability for future remediation of $54.4 million and a charge of $14.3 million, net of taxes and minority interest, as a cumulative effect of an accounting change. This cumulative effect reflects amounts that would have been charged to expense in prior years had SFAS No. 143 been effective for periods prior to Jan. 1, 2003.

2

This change also required additional charges to income for depreciation and non-cash accretion expense in each of the first three quarters of 2003. A summary of these changes is included on page 8. The company will amend and re-file its Forms 10-Q for the quarters ended March 31, June 30 and Sept. 30, 2003 to reflect these changes.

U.S. Cellular Corporation, the nation’s eighth largest wireless service carrier, provides wireless service to more than 4.4 million customers in 147 markets throughout 26 states. The Chicago-based company operates on a customer satisfaction strategy, meeting customer needs by providing a comprehensive range of wireless products and services, superior customer support and a high-quality network.

Investors are encouraged to consider these and other risks and uncertainties that are discussed in documents filed by the Company with the Securities and Exchange Commission.

(1) Market penetration is calculated using 2002 Claritas population estimates for 12/31/03, 9/30/03, 6/30/03 and 3/31/03 and 2001 Claritas estimates for 12/31/02. "Total population" represents the total incremental population of each of U.S. Cellular's consolidated markets, regardless of whether the market has begun marketing operations. The 12/31/03 and 9/30/03 total population counts exclude the population of the 10 markets transferred to AT&T Wireless Services, Inc. in the August 2003 transaction and include the population of the markets acquired from AT&T Wireless Services, Inc. in that transaction. The population of markets in which U.S. Cellular has deferred the transfer of licenses from AT&T Wireless Services, Inc. are not included in the total population counts for any period.

(2) Represents only those markets which have begun marketing operations.

(3) Per unit revenue measurements are derived from Service Revenues as reported in Financial Highlights for each respective quarter as follows:

Service Revenue per Financial Highlights	$	620,639	$	628,440	$	610,109	$	564,601	$	575,387
Components:
Retail service revenue during quarter	$	515,171	$	506,983	$	498,176	$	464,341	$	464,633
Inbound roaming revenue during quarter	$	50,653	$	59,638	$	56,840	$	54,606	$	64,533
Long-distance/other revenue during quarter	$	54,815	$	61,819	$	55,093	$	45,654	$	46,221
Divided by average customers during quarter (000s)		4,328		4,271		4,292		4,178		4,003
Divided by three months in each quarter		3		3		3		3		3
Average monthly revenue per unit	$	47.80	$	49.05	$	47.38	$	45.05	$	47.91
Retail service revenue per unit	$	39.68	$	39.57	$	38.69	$	37.05	$	38.69
Inbound roaming revenue per unit	$	3.90	$	4.65	$	4.41	$	4.36	$	5.37
Long-distance/other revenue per unit	$	4.22	$	4.83	$	4.28	$	3.64	$	3.85

(4) Average monthly local minutes of use per customer (without roaming)

(5) Postpay churn rate per month is calculated by dividing the average monthly postpay customer disconnects during the quarter by the average postpay customer base for the quarter.

(6) Due to changes in accounting for agent rebates, for all periods shown this measurement is no longer calculable using information from the financial statements as reported. The numerator of this calculation is derived by adding Marketing and Selling Expenses and Cost of Equipment Sold, then subtracting Equipment Sales Revenues, then adding the amount of agent rebates related to the retention of current customers for each respective quarter. The numerator is then divided by the number of gross customer unit activations for each respective quarter to arrive at marketing cost per gross customer unit addition.
