Competitive signalling conversion service enables mobile roaming between North America and the rest of the world

Improved conversion service launched as part of
Comfone's complete signalling portfolio

Bern, Switzerland/3GSM World Congress, Cannes, France, 14 February 2005 -Comfone, leading provider of roaming and signalling services to mobile operators in over 100 countries worldwide, today announced the launch of its upgraded signalling conversion service, providing operators with superior global roaming capability for their subscribers as part of Comfone's complete signalling service portfolio.

Mobile operators worldwide require signalling conversion capability to enable end-users to roam between North America and the rest of the world. Conversion services, such as Comfone's new offering, overcome the differences between the various signalling standards found in America (ANSI) and the rest of the world (ITU), further extending operators' global roaming coverage and increasing ARPU (Average Revenue per User).

Comfone customers benefit from a cost-effective solution and the ease of "one-stop shopping" due to the incorporation of ITU/ANSI conversion capability into Comfone's complete signalling service. Comfone Enhanced Signalling provides a signalling network of the highest quality with a choice of over 430 signalling destinations worldwide. These include the highest number of directly connected roaming signalling links currently offered in the market. Roaming coordination for the set-up of all signalling links and a choice of signalling access solutions are some of the add-ons offered by Comfone's service. Extra features include online destination-based statistics for all directly connected links, SMS /MMS Interworking and, now, the very latest in signalling conversion services, too.

Comfone's new conversion service is provided in partnership with Syniverse Technologies, a global communications technology company with headquarters in Florida, USA, specialising in innovative business and network engineering solutions that manage and interconnect voice and data systems throughout the world. As supplier of services to over 300 telecommunication carriers in approximately 40 countries, including the ten largest U.S. wireless carriers, Syniverse is recognised worldwide as a leading provider of conversion technology.
