Basically it is a Zero Ambassador these days, free RM 50 calls/SMSes to Digi no.
Then few years later it allows 50% discount on data, so I had RM 34 for 3GB (instead of usual RM 68) and it was quite a steal considering still no data war that time. This year automatically upgraded my package to 6GB but paying RM 34. However, I still cancelled my data plan as I'm using a dual SIM phone which I'm using my Celcom corporate data that gives me 20GB per month.

Now most of the time I'm paying RM 0 every month unless I buy any Digi deal.
