remember, at the end of the month, say you bought 10GB for R210 or so, and you have not used it up, it will expire. Download frenzy at end of month. With uncapped, even it is shaped, I can download with ease and even go beyond the 10GB without even thinking of topping up. My entire family can use the internet freely without me having to tell them to stop downloading because we only have x amount of data. The day to day headaches of top up and guilt-feeling are gone, and I can concentrate on the work I have to do on the internet.
But, yes, if the user only wants access to internet, and not use the internet to its full potential, then this R139 (1GB data+ line) is sufficient--remember the days when we all started like this, with TI all inclusive for R199 and 1GB data?? 2008 or somewhere there?
