I am interested in the 28 month validity. And on top of that, Data Season pass.

I would like to know how to obtain the 28 month validity?

Do I port in a number, and enjoy 28 month validity without having to pay a sen? I currently have a Tron number, which I dunno whether to keep or not.

If I purchase a new sim pack, how much would I need to pay in total to get 28 Month validity?

Since I would like to purchase a Data season pack of say i.e 10GB@RM50, it doesn't matter if I port in or purchase a new simpack.. both ways I will enjoy 28 month validity, right?

What is the minimum amount of data I can use out of the Season pass? is it 500Mb or 1 MB? 4G or 3G?
