US Patent 8249552 Pre and post-paid service plan manager

A service plan manager is provided, including a manager engine and a storage device to store data for a service account that comprises a pre-paid service plan associated with a first communication device and a post-paid service plan associated with a second communication device. The manager engine determines whether a balance associated with the pre-paid service plan is below a threshold, and communicates a request for increasing the balance to a device associated with the service account if the balance associated with the pre-paid service plan is below the threshold. The manager engine discontinues service for the first communication device until an approval of the request for increasing the balance is received, increases the balance in response to a receipt of the approval of the request for increasing the balance, and adds an amount associated with increasing the balance to an invoice associated with the service account.
