Exhibit 99-a

                                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



Board of Directors, Ameritech Corporation

We have audited the consolidated statements of income, shareowners' equity and cash flows of Ameritech
Corporation (a Delaware corporation) and subsidiaries for the year ended December 31, 1998, as included in
Ameritech's annual report on Form 10-K for the year ended December 31, 1998.  These financial statements are
the responsibility of the company's management.  Our responsibility is to express an opinion on these
financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.  Those standards require
that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement.  An audit includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements.  An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall financial statement
presentation.  We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material
respects, the results of operations and cash flows for Ameritech Corporation and subsidiaries for the year
ended December 31, 1998, in conformity with generally accepted accounting principles.

Our audit was made for the purpose of forming an opinion on the basic financial statements taken as a whole.
The financial statement schedule included in Item 14(a)(2) of Ameritech's Form 10-K for the year ended
December 31, 1998 is the responsibility of Ameritech's management and is presented for purposes of complying
with the Securities and Exchange Commission's rules and is not part of the basic financial statements.  This
schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements
and, in our opinion, fairly states in all material respects the financial data required to be set forth
therein in relation to the basic financial statements taken as a whole.
