Vodafone AirTouch PLC
1 February 2000


        VODAFONE AIRTOUCH AND CASIO COMPUTERS TO BRING THE
         WORLD WIDE WIRELESS WEB TO THE PALM OF YOUR HAND

Vodafone  AirTouch  Plc and Casio Computer Co.,  Ltd.  have  today
announced  a  world-wide agreement for the  joint  development  of
mobile multimedia palm-top computers incorporating a wide range of
wireless  internet content and services.  Set to provide customers
with  a  lightweight handheld device offering full colour internet
access  with audio and video capability, the agreement with  Casio
forms part of Vodafone AirTouch's global platform for mobile  data
and internet access.

'The Vodafone Casio handheld device will provide Vodafone AirTouch
customers around the world with easy access not only to our global
internet  portal,  but also direct access to  the  full  range  of
multimedia text, graphic, video and audio content provided by  our
local  and  global partners over the web,' commented  Chris  Gent,
Chief  Executive of Vodafone AirTouch, 'Our aim is to  become  the
world's leading mobile multimedia operator and our agreement  with
Casio marks another significant step towards achieving this goal.'

Incorporating personal organiser facilities, a full  colour  touch
screen  and an in-built camera, as well as stereo audio and  video
capability,  the  mobile device will give customers  access  to  a
range of additional services.  These will include the sending  and
receiving of picture or multimedia e-cards, the management  of  e-
mail,  diary  and contact information, the ability to  hear  audio
clips  of match reports and the latest music releases and  in  the
near  future,  even view video clips of film previews  and  action
replays of sports highlights - the possibilities will be endless!

The  size  of  a  PDA (Personal Digital Assistant),  the  palm-top
device  will provide Vodafone AirTouch customers around the  world
with   a  complete  out-of-box  solution  for  receiving  complete
multimedia  services wherever they are.  Due to be available  from
the  autumn of this year, the first version of the palm-top device
will  connect  to a digital mobile handset which acts  as  a  high
speed  data  wireless  modem  using GPRS  GSM  technology.  Future
versions will incorporate mobile GPRS handset technology in to the
palm-top  device as a one-piece, off-the-shelf handheld multimedia
access solution.

Providing customers with a rich variety of multimedia content  and
services,  icons pre-installed on the handheld mobile device  will
enable simple click through access from the colour screen to  view
content  and  services from Vodafone AirTouch's partners  via  its
global  internet  portal.  In addition to offering  WAP  (Wireless
Application Protocol) access, customers will be able  to  use  the
palm-top's colour display to access full internet content as  they
would  from  their  fixed  PC, since the palm-top  will  translate
richly formatted web content to fit the quarter VGA colour screen.
The  palm-top computer will also support other internet  standards
such  as  Cookies and Java Script, making true mobile  internet  a
reality.

'Our  strategic alliance with Vodafone AirTouch will enable us  to
combine Casio's acknowledged world expertise in handheld computing
and  mobile  data with Vodafone AirTouch's global reach  to  offer
customers   world-wide  the  ability  to  access   true   wireless
multimedia services,' commented Kazuo Kashio, President  of  Casio
Computer, Tokyo, Japan, 'In our partnership with Vodafone AirTouch
we   aim   to  go  beyond  the  traditional  operator/manufacturer
relationship and work together to bring real benefits to customers
through end-to-end multimedia solutions.'

The  device will support both existing and future technologies and
the  first  jointly  developed palmtop devices will  support  GPRS
technology, connecting to GPRS GSM mobile handsets. Full  3G  (3rd
Generation) services will also be supported when available.

Statements in this press release relating to future status or
circumstances, including statements regarding future performance,
costs, revenues, cash flows, earnings, divestments, growth and
other trend projections and the synergistic benefits of the merger
are forward-looking statements. These statements may generally,
but not always, be identified by the use of words such as
'anticipates', 'should', 'expects', 'estimates', 'believes', or
similar expressions.  By their nature, forward-looking statements
involve risk and uncertainty because they relate to events and
depend on circumstances that will occur in the future. There can
be no assurance that actual results will not differ materially
from those expressed or implied by these forward-looking
statements due to many factors, many of which are outside Vodafone
AirTouch's control, including steps that Mannesmann's management
may take to frustrate Vodafone AirTouch's efforts to obtain
managerial control of Mannesmann, increase the costs or reduce the
benefits of the transaction, the triggering of change of control
provisions in Mannesmann's licences or other agreements, the
ability to obtain regulatory approvals without onerous conditions,
the impact of labour disputes, the risk of negative impacts on
Vodafone AirTouch's credit ratings, the potential costs, including
tax costs, of divesting Orange and Mannesmann's industrial
businesses, limitations on Vodafone AirTouch's ability to control
Mannesmann due to voting restrictions and other provisions of
Mannesmann's charter and German law, general economic conditions,
competition, technical difficulties and the need for increased
capital expenditure (such as that resulting from increased demand
for usage, new business opportunities and deployment of new
technologies), the ability to realise benefits from entering into
partnerships for developing data and internet services, and the
inability of Vodafone AirTouch and Vivendi to agree the detailed
terms for the New Company.
