I would actually prefer a type of prepaid/topup system though, as was mentioned. For example you do not go into the current "free float out of bundle", you buy your bundle and use it, when it's used up you buy another one.[So you basically can't connect if you haven't topped up] Just like the R29, R50 and R110 vouchers you can buy at Pick'nPay for prepaid cells
All this implies : Instant and Multiple Bundles [thus not the current month to month setup]. Plus it'll mean it'll have to "carry-over" , you won't loose unused MB just like you don't loose prepaid minutes.
So ideally i would like to say pay R200 "up front" and use 250 MB, if i'm in the middle of month and it's gone, i'd like to simply put down another R200. The rates should still apply [i.e. buying a R600 bundle gives 1GB etc etc], so you gain the larger the bundle.
Of course the ability to simply free float should still exist , but then it should be contract based [i.e. you pay a special rate ALL THE TIME , so you do not need any bundling ].
Exactly like the cellphone setup. The more you pay per month the better the rates. You do not suddenly go back to prepaid callrates after say 300 minutes if you're on a contract , do you?.
Either way Vodacom will have to impose some sort of 'preventative' measure , because you can get 'online' for extremely low 'startup' costs , and then you can get burnt really bad on the usage [wait till that 50MB windows update start downloading while you're quickly making coffee] .
Imagine you're on MTN and not aware of the R50 p/mb costs.....[points to another amusing thread]
