Now South Africa's cellular operators are on the carpet on price-fixing allegations as the Competition Commission issues subpoenas key people around allegations against MTN and Vodacom.
According to a report in Business Report, the Competition Commission is pursuing an investigation into price-fixing allegations following the network operators' submissions to the Parliamentary portfolio committee set up to find ways of reducing the interconnect rate.
It's still not clear who has been subpoened, or which companies they work for, but interviews are taking place, according to the report.
Co-incidentally, MTN and Vodacom increased their interconnect rates by 500%, to R1,25, in 2001 as Cell C was entering the market.
A number of complaints have been received over the last four years, Business Report says, but action seems to have been spurred by the portfolio committee hearings.
Both companies deny the allegations.
