Minimum Call Length

Monthly Service Charge - Aka: Monthly Fee
Some calling plans charge you a per month fee simply for subscribing to or using its service. It is a set fee regardless of how many calls you make each month. The Monthly Service Charge differs from a Monthly Minimum Usage Charge fee.

Monthly Minimum Usage Charge
This fee is charged by some carriers if your specific rate plan has volume requirements, meaning that you must make a certain dollar amount of calls per month. For example, a plan may require that you make at least .00 a month worth of phone calls. If you do not make .00 worth of calls, the carrier will charge you the difference as a fee. If, for instance, your plan requires a .00 minimum per month and you only made .00 of calls, you would see the remaining .00 as a monthly charge. The Monthly Minimum differs from the Monthly Service Fee .
