Most of the companies provide value-added services to customers which are additional benefits received on purchase of a new product or service. Free value added services are in fact add-ons which can help in building goodwill and increase the revenue if given for a discount price.
Value-added services are generally marketed as premium features and add-ons to basic core functions. Although they can often operate on a stand-alone basis, they are used by telecommunications companies in order to stimulate demand for core services. They are typically not intended to merely diversify the functionality of the product package, but instead provide operational and/or administrative synergy among its range of services. Value-added services are believed to benefit both customers and service providers, as they not only add product functionality for the end user, but also can source enhanced data and analytics for business use.
