Data service revenues reached 3.6% of net revenues in Brazil in Q1 2004, up from 1.5% in Q4 2004. But substantial growth is still likely, both Brazil-wide and within specific regions.Increasing interoperability, the rapid growth of GSM/GPRS networks, and the availability of data-enabled handsets in Brazil are all contributing to an acceleration of data revenues. Itelogy projects data revenues to reach approximately 5% by 2004 and 14% by year-end 2008 in Brazil. Albeit impressive growth in data services, the data market is still far behind the international average of 10%. According to estimates, European services revenues will increase from 16% of net revenues to over 50% by year-end 2010.
