         Item 5.  OTHER EVENTS.

         On July 2, 2001, Arch Wireless Communications, Inc. ("AWCI"), a
subsidiary of Arch Wireless, Inc. (the "Registrant"), announced that it was
deferring an interest payment of approximately $8,287,500 which was due on July
2, 2001 (the "Interest Payment") under AWCI's outstanding 12-3/4% Senior Notes
due 2007 (the "12-3/4% Notes") and that if AWCI did not pay the Interest Payment
within 30 days, it would be in default under the indenture governing the 12-3/4%
Notes (the "Indenture"), which would also then constitute a default under
substantially all indebtedness for money borrowed of the Registrant, AWCI and
the Registrant's other direct and indirect subsidiaries.

         On July 12, 2001, both AWCI and Arch Wireless Holdings, Inc., a
subsidiary of AWCI (the "Borrower"), received letters from The Bank of New York
("BNY"), acting in its capacity as administrative agent under that Third Amended
and Restated Credit Agreement, dated as of March 23, 2000, as amended, by and
among the Borrower, BNY and the other lenders party thereto (the "Credit

         In these letters, BNY stated its belief that AWCI was in default under
the Indenture on the date that AWCI failed to pay the Interest Payment (July 2,
2001) and that, as a result, an event of default under the Credit Agreement
occurred on July 2, 2001 and is continuing.  The Registrant, AWCI and the
Borrower disagree with BNY's conclusion that AWCI was in default under the
Indenture on the date that AWCI failed to pay the Interest Payment.


         Pursuant to the requirements of the Securities Exchange Act of 1934, as
amended, the Registrant has duly caused this report to be signed on its behalf
by the undersigned hereunto duly authorized.
