I've got my t-stick this saturday morning. and asked a sellperson if casual rate can be use. and what he told me was, if I start using it this month then I would be charged $29.95 at the end of this month, which is absurd for someone is not planning to use 500 MB data this month or any other month.. so I check telecom website and related gz threads. And following are my understanding of this plan

1) Price start at 10c per 1 MB ($30 = 300 MB).
2) If you used more than 300 MB but less than 500 MB then you be charge at 29.95
3) below 300 MB usage per month will be pay as you go

It would be great if telecom sellperson know their product better or maybe explain better, especially to new telecom mobile customer.
