Yes
Basically what he's trying to say is that the interconnection rates getting charged all around
does not effect their profit margin on normal usage of the network.
BUT that the consumer is charged for the "delivery fee" anyway.
You run a shop that delivers bread to cafe's
Your bread costs R6, you already have your profit margin on it as it costs you R4 to produce
You charge a delivery fee of R2 to the shops (per bread)
The shop pays R8 for each loaf
If your delivery fee gets halved, you only charge R7 per loaf to the shop. It immediately then translates into a cut in bread pricing to the end consumer.
The end consumer being the cafe's
The bread maker/delivery guy (you) being the cellphone company
Understoods?
