Never said they weren't but they could have done a lot better and so could Cell C. They never took advantage of it both with data and voice. Telkom even cancelled their competitive Smartdata packages. These are all facts if you look back. MTN and Vodacom was able to match them at every turn which wasn't the intention with the lowering of the mobile termination rates.Once again and as in general I agree to disagree. Telkom Mobile is doing just fine and growing by the day even charging at higher than R10/GB. Please don't conflate voice revenue with data revenue. Uncapped data on mobile is definitely not the norm - it's marketed as such but as almost always it is severely constrained especially off-device (ie. mobile hotspot/tethering etc). The drop of speed to 3G is usually around 64-128kbps as a fallback and even when you are within FUP they'll drop your video to 1-1.5mbps for streaming. I'm not sure where you're getting your numbers from but you seem to love to oversimplify the cost. But please, as I've asked before, point me to an uncapped offering without the fine print and FUP for a mobile offering from a regular mobile operator with 10 million subscribers or more that costs less than R1000 even at our crappy exchange rate?
I'm not going to argue with you about the uncapped part as every time these conversations pop up people post the cheap uncapped packages but next time everyone AGAIN acts like they don't exist. True not all of them are but a lot of them are true uncapped.
I'm not oversimplifying the cost of data. There are competent bodies studying these things and even with 3G they put the cost at only a few bucks per GB. Since then we've had HSPA and LTE-A which makes better use of spectrum and the cost has dropped dramatically. We should be paying no more than R2/GB if they took advantage of volumes but instead they hold on to this idea that they must recoup network costs. When in truth if they offer it people will use it.
