I have tried to do a SIM with them for the past 3 months, got an SMS saying it was successful but it's not connecting to the network. I've been to 3 Vodacom stores including their head office in Noordwyk and called the call centre countless times to resolve but nothing! I keep getting sent from pillar to post between the stores and call centre. The number in question is link to insurance that requires the number to be active on the device insured and yet they can't do the SIM swap making the insurance invalid. Make it make sense. Just *******. Not even the managers have been able to resolve this matter regardless of confirmation that they have.
