Hope Maxis is changing to a fairer way of charging... I have noted today that Maxis had recently (from 1.12.2010 if not mistaken) implemented a measure so user would be 'buta-buta' charged for usage beyond the quota.... refer FQA here, extract from the FAQ as follow regarding the usage beyond the quota.
Q How will I be charged once my postpaid Monthly Pass volume quota has been exceeded?
A "When you reach your Monthly Pass volume cap, the session will not be disconnected and there will not be any SMS noti cation. Subsequent usage will be charged at RM0.05/10KB but charges will be capped at a maximum charge of RM250 per bill.
Time-based passes is a new product from Maxis as the mobile internet business gets competitive with new player, YES, coming on board about a month ago.
1 Hour - up to 100MB for RM2.00 only
1 Day - up to 500MB for RM8.00 only.
