According to info posted in the MTN thread, it seems that without a card included MTN is R100 less expensive, for the 1G contract, and with the card included (as is 3G-One), R50 more expensive.
From what i gather it's not really the 'bundled'/'contract' costs that will make the ultimate difference [i.e R500 for 1GB vs. R600 for 1GB] ...it's actually the out-of-bundle rates [R2 p/mb vs R1.25 p/mb ] . Quick calculation shows major cost differences there. Imagine 200MB overshoot every month, that'll be R400 vs. R250. (and overshooting with 200MB on a 1GB account is not that hard i'm sure

).
Quick speculaive calculation :
Vodacom : 150 MB bundle : R150
MTN : R100 MB bundle : R100 + 50MB out of bundle @ R1.50 = R175
So if you stay in bundle, Vodacom wins. Now chances are you won't stay in your bundle on merely 100MB [i know i won't]. Yet you do not want to go for a more expensive bundle and LOOSE money because you haven't used it up.
[HINT : carry over of unused MB is an absolute crucial missing factor here]
So lets say you overshoot and use total of 200MB per month. (That is 50MB overshoot on Vodacom bundle and 100MB overshoot on MTN bundle).
Vodacom : R150 + R100 = R250
MTN : R100 + R75 + R75 = R250
Now it looks equal, except for one catch. You only pay a 'flatrate' of R100 at MTN but R150 at Vodacom . So technically you have a smaller bundle, pay less for it and can -optionally- double overshoot the bundle and still match the vodacom bundle on the MTN system. Now do the same calculation on the 1GB account with R1.25 out of bundle rates....should notice some major saving options on the MTN system especially since the bundle is -already- R100 cheaper ON TOP of the cheaper out-of-bundle rates .....
So defintely something to consider
