They really have made good progress. Extensive 3G and LTE coverage. I travel from Centurion to Richards Bay a 7 hour drive streaming a online radio station with the tunin radio app and the stream does not buffer once. 3G minimum all the way.
Very impressive network but customer service and prices are still way behind. If anything at least they allow for usage of another service provider for data like Axxess and Afrihost so they have that advantage over Vodacom.
