In the 2009 financial year, Vodacom's South Africa business generated R8.6bn in revenue from interconnection, an increase of 8.6% from the previous year. Interconnect is its second-largest source of total revenue (R47bn), after airtime and access (R25.7bn).
It paid Telkom R462m in interconnect fees, while receiving R2.96bn in interconnection payments from the fixed-line operator.
Vodacom, however, does not itemize its direct network operating costs (which includes interconnect) per country. Across the group, it posted R9.79bn in interconnect revenue, with R6.95bn in so-called "interconnect" costs. This would include interconnect payments to other operators, as well as the "true cost" of interconnect.
MTN South Africa, by contrast, generated R6.95bn in interconnect revenue in 2008. Its interconnect and roaming costs totaled R5.14bn. This means a net profit of R1.81bn on interconnect. But MTN admits that "although interconnect revenues were up in the year, the proportion of these to total revenues is gradually decreasing, dropping to 20% in 2008 from 22% in 2007".
