India call tricks : Be careful, Calling cards phone cards for international long distance calling employ this trick to cheat you.
this applies to most India calling cards for all india cards,
Bangalore, Mumbai, New Delhi, Chennai, Hyderabad, Lahore, Karachi city
cards too . What these phone cards or calling cards have is a rounding
mechanism which will fool anyone and especially the ones who are too
careful about the minutes.
of cards have 3 minute rounding
or 6 minute rounding. This means that if you have a 6 min rounding card
and you call for 2 minutes, they will deduct 6 mins from your phone
card. Its no point using a stop watch to calculate and in the end in
such schemes, it will act in their favour if you do so :) . Most cards
employ this sleak trick.. say for 3 minute rounding they have something
like 1+3 minutes rounding. If you end your call in 2 mins, you will
lose 2mins !! Say your card has 30 mins. They will divide it into
blocks of 3 mins each. Now 1+3 mins rounding means they will deduct 1
minute first and then will deduct in blocks of 3 mins.So if you have
spoken for 2 mins, the first block is 1 min, next you have 29 mins ,
divided into 9 blocks and you have already eaten into the second block.
So you lose that block. So now your time remaining is 8 blocks which is
24 mins. So you end up using 6 mins for a 2 min call !!!
