Vumatel dug themselves into a hole with their Vumareach products, they didn't anticipate Openserve lowering their prices as much as they did.
Vumareach was supposed to be for "lower income" areas though their definition of "lower income" seems dubious. Initially a lower cost build to provide these areas with a 20mb service but costumer demand made them introduce a 40mb service and now they are either going to launch a 80mb or 100mb line next year.
Most probably it will cost between R600 and R750 for the the 100mb. If memory serves me right that's within the range of the cheapest options for regular Vumatel fibre.
The problem Vumatel is having is that their core customers want cheaper fibre and their Reach customers want faster speeds.
You would say the logical thing to do is can Vumareach and just lower price of Vumatel services to be in line with Vumareach but they can't do that because Vumareach has much higher contention than regular Vumatel, if they are going to do that if means upgrading the infrastructure of several Vumareach areas and I don't think that will be cheap.
