Sponsored Call enables subscribers to access thematic content channels that provide discounted or free calls in exchange for subscriptions or listening to advertisements. Before call setup, subscribed users receive promotional audio or video messages from advertisers and may earn bonuses such as free minutes or discounted rates.

Subscriptions can be activated via SMS, USSD, IVR (DTMF), or web interfaces. Advertisers manage content through a dedicated web portal with access to statistics and campaign controls.
