Which numbers for which networks (a thread for the casual mobile developer)

HI Guys

Every now and then I develop some sms/wap related application and some of them require that you have to figure out which network a client comes from. I know that number portability screws this up, but a lot of clients didn't make use of number portability, and for my purposes this is fine.

The problem is, networks move over to new prefixes every now and then, and I haven't found a good list of network prefixes (ie Vodacom: 072, 082, etc). I don't develop these apps enough to stay on top of new prefixes

Please help me keep this thread updated whenever a new prefix comes out. It will help other developers too

At this stage I have:

Vodacom: 082, 072, 076, 079
MTN: 083, 073
Cell C: 084, 074
Virgin: (don't have a clue)

Thanks

Virgin is also 074.

Vodacom 071

MTN also use 078

Not sure how this number exercise will help?

If (for example) a MTN 083 number has been ported to Vodacom how will you know??

Yeah, I have an 082 number but am on MTN so wont realy help...
