Digicel Trials Teleglobe for Hosted Application Managed Roaming Service for Intelligent Roaming Selection; Digicel Now Able to I

Teleglobe International Holdings Ltd (NASDAQ:TLGB) and
the Digicel Group, the fastest growing mobile telecommunications
provider in the Caribbean, today announced that Digicel Caribbean will
use Teleglobe's hosted application Managed Roaming service on a trial
basis, enabling Digicel Caribbean to intelligently assign their
outbound roamers onto preferred visited GSM networks around the world.
   Digicel has been a Teleglobe customer since its flagship launch in
Jamaica in 2001. The dynamic company now operates in eight Caribbean
countries with licenses recently secured in Trinidad & Tobago and
Haiti and announced plans, subject to regulatory approval, to acquire
Cingular's Caribbean and Bermuda operations.
   Teleglobe's Managed Roaming service will enable Digicel to assign
a traveling subscriber onto a specific visited network. Digicel may
specify the visited network that provides the best delivery of the
home network suite of services, improving the customer experience and
increasing use of these services, and/or the preferred tariff terms
for roaming, contributing to better average margin per user, or AMPU.
   The Managed Roaming application runs on a platform that is
centrally located on Teleglobe's premises, which will allow Digicel to
rely on a service rather than investing in a system of its own.
Digicel will remain in full control as they remotely manage traveling
subscribers' registration onto preferred visited networks via a secure
web-based interface to Teleglobe's Managed Roaming application.
   "Digicel is continually looking at ways to enhance its services in
order to deliver more value added to our customers and so looks
forward to trialing Teleglobe's global managed roaming service," says
Ian Marwood, Digicel Group Carrier Services Director. "We believe that
by establishing special arrangements with specific roaming partners
and ensuring that subscribers are directed to these networks our
customers will enjoy significant benefits."
   "We are very pleased that Digicel has chosen to trial Teleglobe's
global managed roaming service," said Barry MacCheyne, Vice President
of Wireless Global Sales. "Our service will allow Digicel to
better-manage their roaming business while effectively controlling
their costs, and enhancing the customer experience."
   The feature-rich Managed Roaming service empowers the home network
GSM operator to preferentially select the network for their outbound
subscribers. Out-roaming subscribers are directed onto partner and/or
preferred networks where advantageous roaming agreements have been
established or best service selections can be assured. Margin control
while roaming can be achieved through the use of dynamic preferred
versus random network assignment. In addition to the cost benefits,
the controlled selection of networks ensures improved customer service
and satisfaction.
   Managed Roaming and other hosted offerings to follow build upon
Teleglobe's current signaling services to over 400 GSM operators
worldwide, and uses a well-proven highly reliable signaling network
that spans over 225 countries. Teleglobe hosts the Managed Roaming
application on a rigorously managed, fault tolerant, scalable and open
signaling architecture. The service offers the flexibility to either a
single mobile operator or a group of operators to apply visited
network preference plans on a location-specific basis - by country,
region, state or city.
