Additional minutes refer to the minutes used over the included amount. The number of included minutes is dependent on your plan.
If you go over your plan’s allotted minutes, the overage rate is calculated at 4.9¢ per minute*.
*DETAILS: The 4.9¢ rate is assuming that your phone call used both the inbound-leg and forwarding-leg to complete the call. The inbound-leg is calculated at 2.0¢ per minute, and the forwarding-leg is calculated at 2.9¢ per minute. If your call uses both and inbound-leg and forwarding-leg, your overage charge is the sum of 2.0 + 2.9 = 4.9. If the call came into your UniTel Voice Phone System, and was not forwarded to you (only went to the virtual voicemail) then you would only be charged 2.0¢ in overage for that call.
