FOR RELEASE: IMMEDIATE

TDS AND U.S. CELLULAR RECEIVE NON-COMPLIANCE NOTIFICATIONS
FROM THE AMEX

CHICAGO — Nov. 22, 2006 — Telephone and Data Systems, Inc. [AMEX:TDS, TDS.S] and United States Cellular Corporation [AMEX: USM], as expected and pursuant to prior conversations with The American Stock Exchange (“AMEX”), today announced that both companies received notices from the staff of the AMEX indicating that TDS and U.S. Cellular are not in compliance with listing standards due to their failure to file quarterly reports on Form 10-Q for the period ended Sept. 30, 2006 on a timely basis.

As a result of the non-compliance notices, TDS and U.S. Cellular will be included in a list of issuers, which is posted daily on the AMEX website, that are not in compliance with the listing standards and “.LF” will be appended to their trading symbols whenever such trading symbols are transmitted with a quotation or trade. The AMEX will post both companies to their late filers list on or before Nov. 27, 2006.

The website posting and indicator will remain in effect until TDS and U.S. Cellular have regained compliance with all applicable listing requirements. TDS and U.S. Cellular expect to be in compliance with such listing requirements when they file their Form 10-Q reports for the period ended Sept. 30, 2006. The companies have not filed their Form 10-Q reports for the period ended Sept. 30, 2006 due to a restatement of their financial results for each of the years ended Dec. 31, 2002 — 2005, including quarterly information for 2004 and 2005, and the first and second quarters of 2006. The companies anticipate filing the amended Form 10-K and Form 10-Q reports in December 2006.

TDS and U.S. Cellular will also file Form 8-K reports to report additional matters relating to the notices from the AMEX.
