Update: Vodacom has graciously enabled Circuit Switched Data on my SIM card, however they have confirmed (much to their shock that anyone was asking) that they no longer operate a dial-up service. So the hunt continues for a working dial-up server.
Today I come to ask a question that is equal parts mad and likely entirely futile.
Does Vodacom, or any other mobile network in South Africa for that matter still allow/support ISDN or Analogue data calls?
If so, do any of them still have a dialup service number that works in this day and age...
