GPRS and Java Coming Good

Europe: The number of customers actively using multimedia messaging services (MMS), Java games and GPRS services continued to accelerate over the last two months mmO2 revealed today. Growth in new mobile data services and plans to deliver
significant customer benefits through enhanced market segmentation were detailed
by mmO2 at a presentation today to city analysts and the media.

mmO2 almost doubled the number of MMS active users to more than 180,000 and saw
the number of Java games purchased to date increase from 278,000 to more than
half a million since its last reported figures at the end of March 2003. In the
same period, active GPRS users jumped by 120,000 to 643,000 as more customers
took up O2's Blackberry 'email on the move' solution, with 27, 000 units sold to
date, and sales of the xda from O2 grew to 64,000.

Launched on 2 June 2003, O2 Active has gained more than 60,000 active users and
now around 580,000 customers have compatible handsets. O2 Active is an easy to
use service, offering ringtones, MMS, games, music, video, information and
pictures through a colour icon driven menu.

The success of these services and the continuation of the explosive growth in
text messaging have been further boosted by the company's sponsorship of Big
Brother 4 and other events. mmO2 carried around 2.2 billion text messages during
April and May and UK customers alone sent around one billion SMS's in the same
period.

In addition, mmO2 made a number of other key announcements today in the fast
growing mobile data market. These include:

• Plans for the commercial launch of wLAN in the UK and extended service
offerings in Germany and Ireland. The company aims to offer access to around
1,000 sites across Europe by the end of this year supported by international
roaming through a common O2 interface.

• Results from its recent customer trials of video over mobile and music
over mobile. mmO2 found that breaking news was the most popular video service
and Avril Lavigne topped the music chart.

• The introduction later this year of version two of the xda from O2 - a
combined colour PDA and mobile handset.

• A group-wide agreement with America Online to bring AOL's popular
instant messaging to O2 customers across Europe.

Peter Erskine, chief executive of mmO2, said: 'The mobile data day is all about
providing a greater depth of understanding of the activities that will
contribute to our target of achieving 25% of revenues from data by the end of
2004. We will provide an insight into how mmO2 will continue with its strategy
of growing new mobile data customer propositions and maintaining our lead in SMS
and online services, while keeping strong financial discipline.'
