<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3><B>Waterloo, ON and Singapore
</B>&#150; Small and medium-sized enterprises (SMEs) and retail customers can now
subscribe to the BlackBerry Internet Service<I>&#153;</I> from SingTel. The service
operates on SingTel&#146;s GPRS (General Packet Radio Service) network to deliver email to
customers automatically. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>For individuals and smaller
businesses, BlackBerry Internet Service&#153; allows users to access up to ten corporate
and/or personal email accounts (including Microsoft Exchange, IBM Lotus Domino and many
popular ISP email accounts) from a single device. </FONT></P>

     <P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>Mr.
          Paul Kitchin, SingTel&#146;s Vice President, Consumer Marketing, said:
          &#147;Email is one of the most preferred communications tools around
          today<SUP>1</SUP>. Increasingly, the demand is for access to email even when a
          user is away from his office or home PC.&#148; </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>&#147;Most SMEs here often outsource
their IT functions and they might not have the space or resources to put in an additional
server to integrate with their corporate email and have these pushed wirelessly to them.
BlackBerry Internet Service from SingTel is thus a safe, efficient and convenient way for
them to manage their email on the go. They need not have to worry about missing an
important email from a client, and they can be kept in the loop of business developments
via email at all times.&#148; </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>&#147;For individuals who love being
able to access their email for personal purposes, it is also a cost-effective way of
making sure they do not miss out on a message from their contacts or friends wherever they
are.&#148; </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>&#147;There are many advantages to
&#145;always on&#146; wireless email access and SingTel is pleased that our SME and
individual customers can now share in the growing wireless email market.&#148; </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>The BlackBerry&reg; handheld also
functions as a mobile phone, a personal organizer and offers wireless Internet access
capabilities. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>In December 2004, SingTel will be
offering its customers the new BlackBerry 7290&#153; handheld. It boasts Bluetooth&reg;
support for hands-free voice communications and comes with 32MB of memory for application
and data storage and an enhanced screen and keyboard. The quad-band handheld also allows
users to roam among North America, Europe and Asia Pacific*. </FONT></P>

<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>The BlackBerry 7290 also embraces the
powerful features of the BlackBerry 7200 Series, including a compact and ergonomic
handheld design, high-resolution color screen that supports over 65,000 colors,
easy-to-use QWERTY keyboard, thumb-operated navigation trackwheel, excellent battery
performance, plus integrated support for corporate and personal email, phone, text
messaging, PIM, Internet and intranet applications. </FONT></P>

     <P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>Mr.
          Kitchin said: &#147;Our customers can look forward to SingTel&#146;s robust GPRS
          network and strong international roaming capabilities for support when they
          subscribe to our BlackBerry service. Currently, we offer GPRS roaming to over
          100 networks in more than 90 destinations worldwide.&#148; </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=3>SingTel also offers the BlackBerry
Enterprise Solution&#153; for corporate customers. The take-up for the service has been
very encouraging since its launch in July this year. </FONT></P>
