wait... i see so many ppl saying confirm need to top up rm10 every 90 days?
but according to my calculation:
day 90: top up RM10----(extend 90days)---->
day 180: Buy quota----(extend 90days)---->
day 270: top up RM10----(extend 90days)---->
day 360: Buy quota----(extend 90days)---->
and so on........

So only around RM20 every year to maintain the number, am i wrong?
