Item 5. OTHER EVENTS.

     On July 2, 2001, Arch Wireless Communications, Inc. ("AWCI"), a subsidiary
of Arch Wireless, Inc. (the "Registrant"), announced that it is deferring an
interest payment of approximately $8,287,500 which was due on July 2, 2001 under
AWCI's outstanding 12-3/4% Senior Notes due 2007 (the "12-3/4% Notes"). If AWCI
does not make this interest payment within 30 days, it will be in default under
the indenture governing the 12-3/4% Notes, 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.
