Jannie, I don't give Vodacom too much credit for this freebie. I see the reasons for this offer, in the following order of precedence...
1. Advertising - Billboards have become boring, lets try something different. Rather than spend tens of millions on TV/Radio/sponsorship, changing to red etc etc, give the buggers a bit of free data....hopefully 5 % of them will sign a contract.
2. Let's catch the buggers that go OOB
3. Test out the network under load - i.e.. use the buggers as guinea pigs
4. Lets show the country that we are good guys, and give the buggers a birthday present (although they are hoping for a form of reward)
Maybe the order is not right, but that is how I see it
Oh...thanks Vodacom, now I cannot use my VC contract because my speeds are down to 0.07 Mbps download
