• to compare the cost of subscriber use according to each of the plurality of alternative calling plans to the actual subscriber use during the period of use under the existing calling plan;
• to determine whether any of the calculated costs of the actual subscriber use according to each of the plurality of alternative calling plans are less than the cost of the the actual subscriber use by at least a predetermined savings threshold during the period of use under the existing calling plan;
• and
• to notify the subscriber of the alternative calling plans that cost less than the cost of the actual subscriber use during the period of use by at least the predetermined savings threshold under the existing calling plan if and only if the predetermined savings threshold is greater than administrative costs associated with switching a subscriber to any of the alternative calling plans.
