Billing increments are one of the "hidden" factors that have a major impact your long distance bill.  Services meter your phone calls at set increments to determine the duration of your calls for billing purposes.  The more often they meter, the more accurate their billing, and the less you pay.  Industry research indicates that a service featuring 6 second billing saves the average customer 15% over a similar service which features standard full minute billing.  Therefore, we have factored the savings you get with more accurate billing into all of our itemized billing estimates.
