What is 1-minute rounding?
Typically, your phone call time is measured in seconds. However, when your calls are completed, the duration is rounded to the next second minute. This is called 1-minute rounding or 1-minute increment. Even if your call lasts less than 1 minute, your phone card will be charged for 1 minutes. Again, if your calls are very long, the 1-minute rounding has little impact on your pocket book so please select your phone cards wisely.
