8ta has a deal of 2G (anytime) + 1G FREE (night usage) for R149.
See:
http://8ta.co.za/plans/2gbpromo/
All you have to do is go to an 8ta store and activate a SIM.
Take RICA papers with (ID and proof of residence).
All you do is purchase airtime (anywhere) and convert to the 2G + 1G promo deal.
This is the current cheapest deal in SA, prepaid.
After the Cell C deal ended, I went yesterday and got the 8ta
SIM. Bonus is I use my Cell C dongle modem, and it's 100% compatible with
the 8ta network. It's just as fast as Cell C for me.
PS: Dear moderators, this is not an ad for 8ta, so don't delete this post again. It's a relevant alternative
to Cell C having finished their promo deal. After all, we all have a right to seek affordable alternatives.
That is the point of this site; to compare and liberate consumerism. If Cell C come out with a new offer, I may swing back.
