Based on what is published and made available to public by the telco, you've got most of your facts wrong.
Under Terms and Conditions - Fair Usage policy , #18.
18. Using the BlackBerry device to provide Internet access for another device which is otherwise unconnected, using the BlackBerry device as a modem (known as tethering) or using the SIM card on non-BlackBerry devices will subject the user to be charged based on Pay-As-You-Use rate of 10sen per 10kb.
Excerpted from : http://www.digi.com.my/whatshot/promotions/blackberry/tnc.do
So , let's summarise again for the DG Smart RM58 unlimited plan.
- You will be charged in a pay-per-use manner for tethering
- You will be charged in a pay-per-use manner for using WAP on any other phones besides your registered blackberry (note it goes by the IMEI and PIN).
- WAP and BIS data usage using your registered blackberry (exclude tethering) , is unlimited. This is confirmed with a DiGi cust service agent.
Regarding the unbilled amount screenshot provided by Ramuk in post #160, i am facing the same situation as well. I do no tether, and i only use BIS and WAP on the registered berry. This is my first month, i haven't got to my billing cycle yet, so i cannot confirm if such charges would be finally billed at all, but my feeling is that i won't be billed for what should've been unlimited data, even though the unbilled amount screen lists them out.
Bear in mind that the screen you were looking at was "
Unbilled Amount" screen. Such items could be waived at the monthly bill that you receive. We can always confirm this 'theory' when the monthly bill is issued or via a cust service agent.
good point, which means tethering is not free for digi smart plan.
