Why non voice services are so important for the mobile industry?
3.25 billions, here is the world wide mobile subscribers number by end of 2007, about 50 % of the world population, and a 25 % annual growth. It is a tremendous market, mainly turned towards voice traffic which represents more than 85 % of operators’ revenue. Due to the high level of the competition in mature countries, Average Revenue Per User (ARPU) is slowly decreasing. It’s an absolute necessity for mobile operators to offer new services, other than raw voice, in order to balance voice revenue erosion.
