     This Amendment No. 1 ("Amendment No. 1") amends and supplements the Report
on Schedule 13D, filed on April 4, 2003 (the "Schedule 13D"). Capitalized terms
used herein but not defined herein have the meanings ascribed thereto in the
Schedule 13D.

     This filing of Amendment No. 1 is not, and should not be deemed to be
construed as, an admission that the Schedule 13D or that any amendment thereto
is required to be filed or that any of the Reporting Persons are, for the
purposes of Sections 13(d) or 13(g) of the Securities Exchange Act of 1934, the
beneficial owners of any securities covered by this statement.

Item 1.  Security and Issuer.

     The securities to which this statement relates are shares of Common Stock,
par value $.001 per share (the "Shares"), of Arch Wireless, Inc., a Delaware
corporation (the "Issuer"). The principal executive offices of the Issuer are
located at Arch Wireless, Inc., 1800 West Park Drive, Suite 250, Westborough,
Massachusetts 01581.

Item 4.  Purpose of Transaction.

     From time to time, the Reporting Persons have acquired Shares in the
ordinary course of business for investment purposes and have held such Shares in
such capacity.

     The information set forth in Item 4 of the Schedule 13D is hereby amended
and supplemented by the following:

     On April 11, 2003, the Reporting Persons sent a letter to certain directors
of the Issuer to request a meeting to discuss certain issues relating to
proposals set forth in the Preliminary Proxy Statement filed by the Issuer with
the Securities and Exchange Commission. A copy of this letter is attached hereto
as an exhibit to this Amendment No. 1.

     In connection with the foregoing, the Reporting Persons are considering the
feasibility and advisability of various alternative courses of action with
respect to their investment in the Issuer, and the Reporting Persons reserve the
right, subject to applicable law, (i) to hold their Shares as a passive investor
or as an active investor (whether or not as a member of a "group" with other
beneficial owners of Shares or otherwise), (ii) to acquire beneficial ownership
of additional Shares in the open market, in privately negotiated transactions or
otherwise, (iii) to dispose of all or part of their holdings of Shares, (iv) to
take other actions which could involve one or more of the types of transactions
or have one or more of the results described in Item 4 of Schedule 13D
(including, without limitation, a change in the present board of directors 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), or (v) to change
their intention with respect to any or all of the matters referred to in this
Item 4. The Reporting Persons' decisions and actions with respect to such
possibilities will depend upon a number of factors, including, but not limited
to, the actions of the Issuer, market activity in the Shares, an evaluation of
the Issuer and its prospects, general market and economic conditions, conditions
specifically affecting the Reporting Persons and other factors which the
Reporting Persons may deem relevant to their investment decisions.

CUSIP No. 039392600                13D                        Page 5 of 6 pages
-------------------                                           -----------------

     Except as set forth herein, no contract, arrangement, relationship or
understanding (either oral or written) exists among the Reporting Persons as to
the acquisition, disposition, voting or holding of Shares.

Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect
         to Securities of the Issuer.

     Each of the Funds and Abrams International from time to time may enter into
and unwind, cash settled equity swap or other similar derivative transactions
with respect to the Shares. These arrangements do not and will not give the
Reporting Persons voting or investment control over underlying Shares and,
accordingly, the Reporting Persons disclaim beneficial ownership of any such
Shares.

     Except as set forth in Item 4 of this Amendment No. 1 and as previously
disclosed, none of the Reporting Persons has any contract, arrangement,
understanding or relationship (legal or otherwise) with any person with respect
to any securities of the Issuer, including but not limited to, any contract,
arrangement, understanding or relationship concerning the transfer or voting of
any securities of the Issuer, finder's fees, joint ventures, loan or option
arrangements, puts or calls, guaranties of profits, division of profits or loss
or the giving or withholding of proxies.

Item 7.  Material to be Filed as Exhibits.

Exhibit 99.1   Letter to certain Directors of the Board of Directors of the
               Issuer, dated as of April 11, 2003.
