update: I subscribed to an Internet plan and the RM38 Long life package appears after a while.

RM38 Super Long life plan was in Digi Prepaid Best 2017 plan

but plan already discontinued .. unless u can find them sellers with this old Sim card.

I just simply chose the 1st option when I purchased the Internet plan,
which is NEXT 20 (Auto-renew). I just subscribed because I want to make to make the RM38 plan appear in my box of surprises.
It is just for one time, after that I just unsubscribe the plan.
So actually I have spent RM58 (RM20 the Internet plan + RM38 Super Long life) to extend for one year.

The RM38 will only appear in your box of surprise from the 15th of the month until the end of the month.
