FOR RELEASE: IMMEDIATE

U.S. CELLULAR ANNOUNCES SHARE REPURCHASE PROGRAM
Follows Termination of Possible TDS Offer for U.S. Cellular

CHICAGO - Mar. 6, 2007 - The board of directors of United States Cellular Corporation [AMEX:USM] has authorized the repurchase of up to 500,000 Common Shares of U.S. Cellular from time to time through open market purchases, block transactions, private transactions or other methods. This authorization will expire on March 6, 2010. The share repurchase plan will offset dilution, primarily from employee stock-based incentive compensation plans, preventing a tax deconsolidation that could occur if Telephone and Data Systems, Inc.'s [AMEX:TDS, TDS.S] ownership of U.S. Cellular fell below 80 percent. This authorization is in addition to U.S. Cellular's existing de minimis share repurchase authorization that permits the repurchase of approximately 170,000 shares in each fiscal quarter. There is no expiration date for the de minimis share repurchase program.

On March 5, 2007, TDS, U.S. Cellular's parent company, ended activity related to its possible offer to acquire all of the Common Shares of U.S. Cellular that it does not already own. TDS currently owns approximately 80.7 percent of U.S. Cellular common stock. On Feb. 18, 2005, TDS announced that it might at some point in the future make an offer to issue its Special Common Shares in exchange for all of the remaining Common Shares of U.S. Cellular which are not owned by TDS. The intended purpose of such a transaction was to make U.S. Cellular a wholly-owned subsidiary of TDS.

To consider a possible transaction, if and when one was announced by TDS, the U.S. Cellular board established a special committee of U.S. Cellular directors that are not directors or executive officers of TDS. The special committee has been dissolved following TDS' announcement that it has ended activities related to a possible offer to acquire U.S. Cellular Common Shares.
