Oh dear...
It looks like everyone's fallen for the trick already. Read the other articles, guys - talks broke down with ICASA, and this cut is nowhere near acceptable, even to ICASA, never mind parliament, or consumers. Not only is this a very clever publicity stunt, but it actually also a blatant lie.
Do the sums:
R1,25 less 19% = R1,01 peak rate
R0,77 less 19% = R0,62 peak rate
Now "blend" those two numbers, say 60/40 day/night (which is really quite an unlikely level of night-time calls, but for the sake of argument), and you get:
86c !!!!
To get a figure of 78c, you have to assume that 60% of calls happen at night. Really? Fixed to mobile?
Not only is the number a lie, but they currently offer on-net retail rates below those values on their networks. So much for "cost-based".
Even if they passed on the entire benefit on retail rates (which they obviously won't), you get something like:
Current retail price: R1,50 less 24c (as above), and you'd be paying R1,26. That's still not much of a drop, given everything we've heard to date.
In summary, MTN and Vodacom have cut their interconnection rates by 19%, unilaterally, without agreement from anyone else, not even ICASA, and have made up a number (78c) that they think the public will like to hear. Magnanimous, I'm sure, but it's obviously not going to stop here... Watch this space.
