Changes in Registrant's Certifying Accountant. (a) Previous Independent Accountants On August 29, 2001, VoiceStream Wireless Corporation ("VWC") dismissed Arthur Andersen LLP ("Andersen") as its independent accountant The audit reports of Andersen on the consolidated financial statements of VWC and subsidiaries for each of the years in the two-year period ended December 31, 2000 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles. The decision to change the independent audit firm was recommended by VWC's Audit Committee and approved by VWC's Board of Directors. During the two years ended December 31, 2000, and the subsequent interim period through August 29, 2001, there were no disagreements with Andersen on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements if not resolved to Andersen's satisfaction, would have caused them to make reference to the subject matter of the disagreement in its reports on the consolidated financial statements for such years. During the past two fiscal years and through August 29, 2001, Andersen has not advised VWC of any reportable events (as defined in Item 304(a)(1)(v) of Regulation S-K under the Securities Exchange Act of 1934). VWC requested that Andersen furnish it with a letter addressed to the Securities and Exchange Commission stating whether or not it agrees with the statements above and, if not, stating the respects in which it does not agree. A copy of such letter is attached hereto as Exhibit 16.1 and is incorporated herein by reference.
