Well you can be better off with this IF you only go over your limit by a few MB's. Compare this with the other providers who ask you to buy a big bundle of data even if you only need a few MB's. Sometimes, this is overkill.
I want to be able to top up like the iBurst guys can. Let me buy another gig off you for R200 or whatever it costs but not R1000!!! And does anybody know if it is going to roll over tomorrow because it is a holiday? It is going to suck if I have to wait for 2 May to get more data...
