Digi changed already. Now Digi only subsidize 50 bucks for any digi numbers called, smsed or mmsed. I'm using one. And got commitment already. Forgot how much. But as far as i know, the call rate is the cheapest among all (iirc).

And also sometimes digi has promotion for ambassador line users. Like data plan unlimited usage. Digi giving 50% off for ambassador line users.

And I think working for digi promoters under an event company doesn't make you a digi stuff tho'. Ambassador line is given to those stuff working directly under digi. =)

How does it works ?
If you happens to know anybody working permanently for digi, you can ask from them (Your friends or family members that working for digi). Then they'll know what to do. =)

I'm not sure if it's mentioned before, but how do I check my ambassador status? Cause I called digi customer careline and asked whether they have the promotion for the 50% off for the data plan or not. And the guy told me don't have. Anyone renewed theirs? I mean for the 50% off for the data plan.
