I received a Free ADSL DATA voucher from Incredible Connection for 39GB to use over 12 months. I am already subscribed to Cybersmart. 1 - Is there any cath to this free voucher? 2 - Can I use it while still with Cybersmart 3 - Can someone please refer me to a Dummy's guide on how to set it up on a telkom Closer ADSL Router and how to switch between the to ISP's?
