No, I don't. The Internet provided by the Univeristy (Stellenbosch University) is more than I need. When I'm not within its range, for example I go to the mall, there's always free WiFi that I can access simply by using my Facebook Details.
I have an account, but only use it when nothing else is available. I don't understand why they have monthly expiring bundles at prices that are barely better than mobile data rates. Screams ripoff. The slow speeds and tiresome continual logging, even when you check remember me, isn't worth the frustration and wasted time.
