FOR RELEASE: IMMEDIATE

U.S. CELLULAR REPORTS STRONG SECOND QUARTER RESULTS

July 21, 2004, Chicago, Illinois — United States Cellular Corporation [AMEX:USM] reported service revenues of $662.7 million for the second quarter of 2004, up 9 percent from $610.1 million in the comparable period a year ago. The company recorded operating income of $65.9 million during the quarter, an increase of $62.4 million from the second quarter of 2003, as restated. Operating expenses in 2003 included a $49.6 million loss, as restated, on the impairment of certain intangible assets and a $3.5 million loss related to the then-pending exchange of U.S. Cellular’s Florida and Georgia properties with AT&T Wireless Services, Inc. [NYSE:AWE] (“AT&T Wireless”). Net income and basic earnings per share were $38 million and $0.44, respectively, compared to a net loss and basic loss per share of $1.7 million and $0.02, respectively, in the comparable period one year ago, as restated.

Second quarter 2004 operating results do not include any results from operations of the Florida, Georgia and south Texas markets that were either traded or sold to AT&T Wireless. The Florida, Georgia and south Texas markets contributed $42.9 million of service revenues in the second quarter of 2003. A reconciliation of the service revenues follows later in this press release.

Second Quarter Highlights

Customers totaled 4,684,000, an 8 percent increase from 4,343,000 customers one year earlier.
Net customer activations from distribution channels totaled 137,000 during the quarter, compared to 103,000 activations for the same quarter of 2003.
For the quarter, the company recorded postpay churn of 1.5 percent, which is favorable to industry averages.
Average monthly retail service revenue per customer increased 5 percent year-over-year in the quarter to $41.58, compared to $39.69 in the same period a year ago.

President’s Comments
“We are very pleased to report yet another quarter of exceptional operating performance at U.S. Cellular,” said John E. Rooney, president and chief executive officer. “We added 137,000 net customers in the quarter, up 33 percent from the second quarter a year ago, bringing net additions for the first half of the year to 333,000. The strong net add performance, coupled with higher retail service revenue per customer unit, drove service revenue growth of 9 percent. When adjusted for those markets traded or sold to AT&T Wireless in August of 2003 and February 2004, service revenue grew 17 percent.

“This excellent performance is a direct result of our ‘Customers expect it; We deliver!’ customer strategy. Truly satisfied customers share their experiences, which is why it’s not surprising that word-of-mouth referrals account for a meaningful number of our new customers. Fully supporting that passion about customer satisfaction are our competitive service offerings, broad distribution and high-quality network. We further improved our network during the second quarter, adding another 298 cell sites, so that we now have 4,420 sites providing excellent coverage in our markets. Our continued efforts to deliver high levels of customer satisfaction resulted in another quarter of low postpay churn, at 1.5 percent.

“More recently, we began offering service in Oklahoma City and Lincoln, Nebraska. Both of these market launches are good examples of our strategy to expand our service into contiguous markets. During the quarter we plan to initiate service in Portland, Maine, the only portion of the state in which we do not currently offer service. These efforts and our strong performance for the quarter underscore the fact that we have a sound strategy and are delivering on it.”

Financing Matters
During the quarter, the company sold $330 million of 7.5 percent Senior Notes due 2034 and $100 million of 6.7 percent of Senior Notes due 2033. The company will use the net proceeds to redeem all of its 6 percent Liquid Yield Option Notes due 2015 and all of its 7.25 percent notes due 2007 during the third quarter.

Market penetration is calculated using 2003 Claritas population estimates for 6/30/04 and 3/31/04 and 2002 Claritas estimates for 2003. "Total population" represents the total population of each of U.S. Cellular's consolidated markets, regardless of whether the market has begun marketing operations. The 6/30/04 and 3/31/04 total population counts include the population of the market added to consolidated operations as of 1/1/04, but exclude the population of the six markets sold to AT&T Wireless in February 2004. The 12/31/03 and 9/30/03 total population counts exclude the population of the 10 markets transferred to AT&T Wireless in August 2003 and include the population of markets acquired from AT&T Wireless in that transaction. The population of markets in which U.S. Cellular has deferred the transfer of licenses from AT&T Wireless are not included in the total population counts for any period.

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