Hey guys. I don't know if this is the right thread to post. There are too many threads I saw but I don't know which one is the best one. @__@

Anyways, I am very confused about Celcom Postpaid. I saw different types, do they have different features? I was thinking of changing to Postpaid sometime soon. Can you change from Prepaid to Postpaid without changing the number?

If I use Postpaid, how do they charge for Internet usage?
