Spoke to a maxis rep yesterday about these data concerns. Let me share with you. Maxis measures the amount of data you use at about 2AM every morning. That is the point where the server will decide if you are nearing your limit and will form the decision of whether to send or not to send an sms notification.

However, they also have a policy of not disturbing customers by sending sms at 2AM. The system will instead send it later on the morning at about 9 to 11AM. If you somehow are already spending past your limit between 2AM to the time that they send you the sms .... Well you know.


His advice to me is for the first month, closely measure the data usage and close off the cellular data when it is close to the limit and wait for the bill. Then compare with what you measure and what is in the bill. This way you can see if the iphone's measurement tallies with maxis.

I feel sorry for u guys...
