                                       3

This Amendment No. 6 to the Schedule 13D of TDC A/S (formerly Tele Danmark A/S)
("TDC") relates to the beneficial ownership by TDC of the Common Stock, par
value U.S.$0.001 per Share (the "Shares") of Hungarian Telephone and Cable Corp.
(the "Issuer"). This Amendment No. 6 amends and supplements the Schedule 13D of
TDC filed on July 15, 1997, as amended by Amendment No. 1, Amendment No. 2,
Amendment No. 3, Amendment No. 4 and Amendment No. 5 thereto (the "Schedule
13D"). Capitalized terms used but not otherwise defined in this document have
the meanings assigned to them in the Schedule 13D.

ITEM 3: SOURCE AND AMOUNTS OF FUNDS OR OTHER CONSIDERATION.

Item 3 of the Schedule 13D is hereby supplemented by adding the following:

On March 30, 2005, TDC entered into an agreement to acquire (i) 2,750,936
Shares, (ii) 12,000 shares of the Issuer's Series A Convertible Preferred Stock
and (iii) warrants entitling the holder to purchase an aggregate of 2,500,000
Shares. The aggregate purchase price for those is $79,933,292. TDC will fund the
purchase price out of its working capital.

ITEM 4: PURPOSE OF TRANSACTION.

Item 4 of the Schedule 13D is hereby amended and supplemented by adding the
following after the seventh paragraph of such item:

TDC entered into a Securities Purchase Agreement, dated as of March 30, 2005
(the "SPA"), with Ashmore Global Special Situations Fund Limited, Asset Holder
PCC No. 2 Limited Re Emerging Economy Portfolio, Asset Holder PCC Limited Re:
Ashmore Emerging Markets Liquid Investment Portfolio, Ashmore Emerging Markets
Debt Fund and EMCD Limited (collectively, the "Sellers"). Pursuant to the
provisions of and subject to the conditions set forth in the SPA, TDC agreed to
acquire from the Sellers (i) 2,750,936 Shares, (ii) 12,000 shares of Series A
Convertible Preferred Stock and (iii) warrants entitling the holder to purchase
an aggregate of 2,500,000 Shares.

TDC's decision to increase its equity ownership in the Issuer by acquiring the
Shares and other securities described in the SPA followed a strategic review by
TDC of how to optimize its investment in the Issuer. In the course of that
review, TDC considered various alternatives, including the possibility of
acquiring 100% of the equity interest in the Issuer. TDC concluded that at the
present time, its strategic and other interests are best served by acquiring a
controlling interest in the Issuer and that it would not seek to acquire 100% of
the equity interest in the Issuer. Acquiring a controlling interest in the
Issuer will, among other things, permit TDC to consolidate its investment in the
Issuer for financial reporting purposes. Acquiring less than 100% of the equity
interest in the Issuer will permit TDC to retain greater flexibility in respect
of the Issuer, including retaining the Issuer's current ability to access the
capital markets or to use its Common Stock as an acquisition currency.

TDC expects that it will continue to evaluate regularly its investment in the
Issuer and, depending on the results of any such future review, it may decide to
alter its strategy in respect of its investment in the Issuer, and accordingly
may increase or reduce its interest in the Issuer.

Except as set forth above, TDC has no present plans or proposals which relate to
or would result in:

         (a) The acquisition by any person of additional common stock of the
Issuer, or the disposition of common stock of the Issuer;


                                       4

         (b) An extraordinary corporate transaction, such as a merger,
reorganization, or liquidation, involving the Issuer or any of its subsidiaries;

         (c) A sale or transfer of a material amount of assets of the Issuer or
any of its subsidiaries;

         (d) Any change in the present board of directors or management of the
Issuer, including any plans or proposals to change the number or term of
directors or to fill any existing vacancies on the board;

         (e) Any material change in the present capitalization or dividend
policy of the Issuer;

         (f) Any other material change in the Issuer's business or corporate
structure;

         (g) Any changes in the Issuer's charter, bylaws, or instruments
corresponding thereto or other actions which may impede the acquisition of
control of the Issuer by any person;

         (h) Causing a class of common stock of the Issuer to be delisted from a
national securities exchange or to cease to be authorized to be quoted on an
inter-dealer quotation system of a registered national securities association;

         (i) A class of common stock of the Issuer becoming eligible for
termination of registration pursuant to Section 12(g)(4) of the Securities
Exchange Act of 1934; or

         (j) Any action similar to any of those enumerated above.

ITEM 5: INTEREST IN SECURITIES OF THE ISSUER.

Paragraphs (a) and (b) of Item 5 of the Schedule 13D are hereby deleted and
replaced in their entirety by the following:

(a) - (b)TDC beneficially owns 10,799,782 Shares of the Issuer (including any
         Shares that will be owned or will be deemed to be beneficially owned
         pursuant to the SPA) and such Shares constitute approximately 69.8% of
         the outstanding Shares of the Issuer. Of the 10,799,782 Shares
         beneficially owned by TDC, (i) 7,999,782 Shares are or will be owned by
         TDC, (ii) 300,000 Shares are or will be deemed to be beneficially owned
         by TDC because TDC owns or will own 30,000 shares of Series A
         Convertible Preferred Stock of the Issuer, each of which is convertible
         into ten Shares at the option of the holder of those shares and (iii)
         2,500,000 Shares will be deemed to be beneficially owned by TDC because
         TDC will own warrants to purchase an aggregate of 2,500,000 Shares.

         TDC has the sole power to vote and dispose of all of the 5,248,846
         Shares it currently owns and, if TDC converts its 18,000 shares of
         Series A Convertible Preferred Stock, it will have the sole power to
         vote and dispose of the Shares acquired upon conversion. In addition,
         upon consummation of the transactions contemplated by the SPA, TDC will
         have the sole power to vote and dispose of all of the 2,750,936 Shares
         it will own pursuant to the SPA and, if TDC converts its 12,000 shares
         of Series A Convertible Preferred Stock and exercises its warrants to
         purchase 2,500,000 Shares, it will have the sole power to vote and
         dispose of the Shares acquired upon conversion.

ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
         TO SECURITIES OF THE ISSUER.

As described in Amendment No. 5 to the Schedule 13D, TDC and the other parties
to the SPA entered into a stockholders agreement, dated as of September 3, 2004
(the "Stockholders Agreement"). The Stockholders Agreement will terminate upon
the consummation of the transactions contemplated by the SPA.
