Vodacom Voicemail Notification

[Moni88]

I have been struggeling for months now with my dads phone to get vodacom to send an sms when he has a voicemail. It is set up on the menu by 121 but it still does not send a sms notification....

I thought this was automatic behaviour? I've always gotten the SMS notification and I never set anything up...
