The RM 68 plan is applicable for the BB and unlimited internet. If you're using BB you'll subscribe to BIS .. other phones get unlimited internet. The quota is 3gb if not mistaken and internet will be slower after that.

The save smart is when your total phone bill is more than RM 100 you save 25% of the RM 68 and if your total bill is more than RM 200 than the RM68 is waived

what a friend of mine did for the iphone deal was to port to digi first and after that go get the package/phone/deal you want
