What is Rounding?
Some calling cards round to the nearest second, minute, others 3 minutes etc. Rounding means they measure your talk time in increments. For example if a card is advertising 3 min rounding and you talk for 1 minute the telecom company will round up to 3 minutes and charge your card for 3 minutes of talk time. If you talk for 5 minutes the company will round up to 6 minutes and take away 6 minutes from your card, if you talk for 20 min the Telecom company will take away 21 minutes from your card and if you talk for 12 minutes they wont take away any additional minutes because 12 minutes is an exact increment of 3. The lower the rounded minutes or seconds the better the value of the pre-paid calling card.
