stomp? lol...grow up please. anyway, it's your own ernest to use
manual detection. Few years ago, I've been paying singtel bills for
sms from malaysia to singapore when I were in Singapore seas.
Few months back, I called to a country in Asia (not Singapore)
while I was in malaysia. A 5 minutes phone call cost me $30. 1 min
cost $6.
A mobile phone is for people to find you while you're on the go.
If you wanna chit chat, do it using a house phone. This is the
convention. 
Are you mentally retarded? Did you even understand the TS's
issue? Just because you paid $30 for a 6 minute call to 'some other
country' doesnt make it something you should be proud of. In fact,
I find it quite stupid and ignorant. Seeing how you could have
bought a local calling card for 1/3 the price and spoke to that
'other country'' for god knows how much longer a time.
Anyway that is far besides the point. The TS asked if he has a
case against starhub for CHARGING him as though he was overseas
when he was actually in Singapore. Happened to me a few times while
I was in Camps down at changi. They HAVE to waive of the charges.
Call the call center. Make a big fuss. If they dare to say 'oh you
could have passed your phone to your friend who went over seas
what' then demand the call list (they have one) and you will see
over a span of a few hours some calls 'from' overseas and some from
Singapore. Then ask them how that happen? Play tennis with your
phone throwing it back and forth from overseas ar?
Switching to manual detection is a solution to this problem, BUT
IT IS NOT YOUR DUTY NOR OBLIGATION. It is your prerogative to use
your phone within the confines of your country withouot having to
worry or stress. Make uber big noise about this issue. If not all
the poor people living in woodlands and changi all kenna taken
advantage of. No idea how much they are ripping off innocent people
who dare not challenge big companies.
Good luck and
Cheers!
P.S - I have personally had very good experiences with star hub
customer service. No worries, normally they will just waive it and
apologies. Very nice people. Unlike Shit-tel. Retarded customer
service.
