It's a mistake to base pricing on a cost-plus model. And while I don't like paying the price of SMSs here or anywhere else, I would even less approve of using political or legislative pressure to interfere with the way businesses price their goods and services.
If you were a programmer or consultant, how would you like it if the government regulator said you had to price on cost-plus?
Think about it for a millisecond: The incremental cost of producing another copy of software is virtually zero. Cost-plus regulation would mean you'd have to sell the first 5000 copies at say R1000 each, and then drop the price to 5 cents thereafter. But almost no-one would buy at R1000 a licence. They'd rather wait, expecting the price to drop ... and that wouldn't happen because the publisher could never sell enough to recover cost. The market gets severely distorted, and soon the range and quality of software drops dramatically because no-one can price freely and make their own choices about cost amortisations.
Same holds for telecommunications and data services and all others goods and services.
The real problem is that we don't have a free and open market in telecommunications and data, but a tightly-controlled cartel protected by the state. Neither you nor I can start up our own telecoms company and compete with the incumbents - we have pay vast "licence" fees upfront and annually to Caesar (the state) for "permission" to operate. This is deeply unjust and an unwarranted intrusion in the free market.
And if you think an unregulated market will lead to chaos, you need to think again. Do you know which country in Africa has the best, fastest and cheapest telecommunications services on the continent? The only one with an unregulated market - Somalia! Google it if you don't believe me. (Edit:
here's an old article from
eight years ago, on the BBC (which is very suspicious of private enterprise) - since then prices have dropped much further, and services improved.)
Rather than push for yet more regulation and control, we should be pushing harder for less state interference and the abolition of all administrative controls, licence fees and barriers to entry by other players. It's the only real and sustainable way of getting sanity into the pricing models.
