Calling plan information is provided whenever a user makes a call that
fits within the plan. The user may be assigned an account related to the
calling plan with information associated with the account. The
information may include a time function such as the time remaining until
expiration of the calling plan or the time used in the calling plan. A
call made from an originating number that is associated with the calling
plan triggers the provision of information. After the information is
provided, the call may be routed to a terminating number as dialed by the
user. After the call, the information associated with the calling plan
may be updated.
