From your calculation, means that Starhub charge per seconds, which is 15cents per minute, or 0.25cent per second. (example: The call lasted 90 seconds. 90s * 0.25cents per second = 22.5cents)
Am I right?
That means Starhub will count very accurately. Thus, there is definetely IMPOSSIBLE K.subra will get this kind of bill. I think K.Subra can report to Starhub Service Centre and check more details on your bill maybe.
p/s: by the way, my phone can count the total call duration in unit of seconds.
Partially correct, if every call is more than 1 min.
But if a call is less than 60 sec or 1 min, the charge is still charge 15cent minimum.
Meaning is when making outgoing call is 20 sec, the charge is still 15 cent.
As for @Ksubra mentioned ["always increase the minuts"].
This is to mean that there are several outgoing calls is less than 1 mins; of which Starhub system will automatic add to minimum of 60sec (for calculation purpose)
Unless all his calls are more than 1 min.
This is why i stated that it will be quite impossible to manually calculate using the mobile phone log.
There is a VAS to check your usage on call timing.
The VAS term is "Itemized Bill" of $5.35 monthly with activate cost $10.70 one time charge.
At the mobile plan, there is a "Select" drop down box, and
select "Add Value-Added Service" will go to the "Vaue-Added Services" page.
Under the "Itemized Bill", is the description.
We can add or delete any VAS ourself, thru this way.
