Value for money MTN seems to have got it right. The other deals seem to compensate for the cheaper prices by shaving off a lot of other things like voice. I don't even like MTN, but they did just enough (by SA's standards, which isn't much), and undercut Vodacom immensely.
agreed on the Telkom deals, quite good.
their SMS model is also quite good i think... send 5, get 50 free if i remember correctly.... better that them offering you 500sms and they think they doing u a moerze favour, if u hardly use SMSs
but... FNB's offering seems to loose a bit of sparkle no? they're cheaper, but no airtime or data.... e.g. for R30 more pm can rather get the Telkom deal on the lower offerings. but then it does leave you free to do what u want
