If I subscribe to Maxis Value Plus plan (postpaid), let's say Value Plus 50, which mean I will have RM50 credits to spend.

My question is, if I get for example (Mobile Internet 1 day pass - RM8 or Mobile Internet monthly 100MB pass - RM18), will I get extra charge on top of my Valus Plus plan or, Maxis will deduct part of RM50 credits?

Currently, Maxis is deducting my RM50 credits, if Pay Per Use.
