Nieuwegein, the Netherlands, 19 March 2002 - Telesp Celular, a subsidiary of Portugal Telecom and leading wireless operator in South America together with CMG, have successfully conducted multimedia messaging tests in Brazil over a 2.5G CDMA 1xRTT network. Multimedia Services enable wireless messaging that includes photographs, images, animation, sound and texts.

Dick Blom, president CMG in Latin America, said that this is the first successful MMS testing over such networks in the world. "The test once again confirms CMG's capability to work with all 2G technologies (TDMA, CDMA, GSM) and their evolution to 2.5G and 3G. This is a milestone for both companies," he said.

Carlos Vasconcellos, president Telesp Celular, said that the project is extremely important and strengthens Telesp Celular's policy of developing products and services in an innovative fashion to meet the individual needs of users and companies. "The high-speed mobile Internet will cause a vast impact on the market changing the way how companies do business and provide individual customers with convenience. This translates into user-friendly services that facilitate communication among people and provide access to services that save time for customers," said Vasconcellos.

Telesp Celular, a pioneer in Brazil and Latin America in 2.5G wireless data services, was chosen for the soft launch of MMS because the operator is a leader and a benchmark in mobile data services in Brazil. "The company has a history in innovations that is respected not only in Brazil but also around the world," said Blom.
