Has anyone else noticed that K'nect data doesn't last anywhere near as long as eg Vodacom's. The difference in price is crazy - +/- 95/Gb from Voda and 19.50 from K'Nect, but does K'nect actually give you a Gig for your 19.50 Buckses. And is there a technical difference in the "type" of data that different operators offer. I may be using all the incorrect terminology here but I hope you get what I'm trying to say?
