Tecnomen Corporation       PRESS RELEASE     12 December 2003


Tecnomen has supplied a prepaid system worth around 3 million euros to
Argentina’s CTI Móvil, a subsidiary of the América Móvil Group, for
their new GSM network. CTI Móvil launched the service to its customers
in December.

Tecnomen is now a supplier to eight operators controlled by the
América Móvil Group in Latin America. América Móvil is the leading
provider of wireless services there with millions of subscribers
throughout the region.

CTI Móvil, Argentina’s fourth largest mobile operator, holds licences
to provide nationwide wireless service in Argentina, a country with a
population of approximately 37 million people.

"We are pleased with América Móvil’s continued confidence in
Tecnomen’s products. This deal demonstrates Tecnomen’s commitment to
providing advanced but cost-effective prepaid services in Latin
America," said Oscar Fernandez, Managing Director Latin America.

With the help of the feature-rich Tecnomen Prepaid platform, CTI Móvil
can selectively group and target the features provided by the platform
to meet the needs of their specific market segments. Tecnomen Prepaid
does not impose any restrictions on SIM card or handset type, and
simultaneously supports different protocols including TDMA, GSM and
CDMA. It supports SMS charging and roaming, allowing subscribers to
benefit from a prepaid service whilst travelling abroad.
