Hi all, need some suggestions/advices from you guys since you guys here are pro.

My parents current plans:
Dad: Digi Postpaid 60 (Senior discount RM10) 60GB data - RM50+6% SST
Mum: Digi Postpaid 50 (Senior discount RM10) 50GB data - RM40+6% SST

I would like to change their plan to prepaid because it seems like prepaid offered much better package and also no need pay for the 6% SST (right?) lol

Look forward from you guys ya, thanks in advance.
