Actually, if they scap the pay-per-gig model and everyone sells uncapped it will work.
At the moment my parents use 1gb a month, thus they buy 1gb per month. Heavy users pay more for uncapped, but only heavy users see the need to buy uncapped.
Imagine for a moment if we had only the following options in this country:
384k uncapped for R100pm
512k uncapped for R200pm
1m uncapped for R300pm
2m uncapped for R400pm
4m uncapped for R500pm
6m uncapped for R600pm
8m uncapped for R700pm
10m uncapped for R800pm
This would mean that EVERYONE is on uncapped, but only a fraction of that would be heavy users. Thus, the light users subsidizes the heavy users. Sure, some users will download 100s of gigs a month, but others only 1 or 2. By giving all the users the choice of speed rather than cap you can still choose what you want, but you pay more for speed, not for how much you use it.
The reason uncapped might fail in SA is because of the capped model. Who would pay R100pm for uncapped if they can pay R19 per month for 1gig and they know 1gig is enough?
P.S. If we could get telscum to drop the line rentals this model could actually work, eg make a 384k line with uncapped data R150pm, thus the end user price is the same, but telkom only takes R50pm.
Also make per gig models illegal otherwise people would still stick to them.
But we all know how great I***A is at bridging the digital divide and helping SA get out of the internet stone age.
