I'm not that familiar with prepaid, is it ok for me not to reload it till the next month? I don't download everyday, thinking doing it just one week per month. Do I have to buy a new sim card every month? I don't want to topup for the 30 days as I won't be using it that much.

So, I still have to buy the prepaid in order to ensure the line won't be terminated. Ugh, RM 30 per month, I guess consider as OK since can download like krazy
