Digicel Trials Teleglobe for Hosted Application Managed Roaming Service for Intelligent Roaming Selection; Digicel Now Able to Intelligently Assign Their Outbound Roamers onto Preferred Visited GSM Networks around the World.

HAMILTON, Bermuda -- 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.
