On Vodacom you can go from contract to prepaid, the secret is to ask....its one of those services that are there, but you have to ask, the information does not get volunteered.....I wonder why- - - LOL....
you can on vodacom, but mtn says thier systems wont allow the change. so if youre an mtn subscriber, and you want to keep your number, you HAVE to port it... thats one sure way to loose customers!
