just some question for smart plan.

if i subscribe smart plan, can i have 2 RM30 Subline and 1 RM10 subline?

with the above plan, my total bill has been over RM100. will my smart plan get 50% discount or i have to use up RM100 (68+32 call) to enjoy my 50% discount?

hope some 1 can clarify for me. thanks
