Yes,

Unless they have new plan, else i dun think they will remove it.
Else u may try rm70 mnp plan or digi ambassador rm68 plan

You cant convert your current DG plan to MNP70 plan. If you really wish to have this discounted plan you must MNP from others telco to this MNP70 plan.

For Ambassador 68 plan, this plan not open for public to subcribe.
Do you have any friends or family members who are DG staffs? If yes ask them if they still have any ambassador slot and register your NRIC into the Ambassador program.

Cheers.

Try port to Umobile if not that good after 30 days u can port back to DG and subcribe the MNP70 plan.
- I suggest Umobile cause the plan the offer not that bad
