There are two main reasons for the popularity of the pre-paid services, despite the high unit call cost, viz. (1) the mobility, and (2) the absence of a recurrent cost. Very clearly, both of these are premised on a very simple principle (which I wish the marketing morons out there would realise) - reinforcement of basic freedoms. This is also the fundamental driver behind the inexorable success of open source. In the case of mobility, freedom of location has provided a greater chance of success for traders, work seekers, and so on. In the case of the absence of a recurrent cost, this freedom of choice is very relevant to those without a recurrent and constant income, whilst not losing the opportunity to remain connected (ability to receive calls anywhere at no charge to the person being called). Obviously, none of this applies to the Telkrap offerings, which is why they will never be regarded with any sort of favour, except by those with a few Khulisa shares. Getting back to the cell providers, it should be very apparent that they interfere with these basic freedoms at their peril...
