Abstract
A combination of Global System for Mobile communications (GSM) capabilities including Short Message Service (SMS), Subscriber Identity Module (SIM) and Customized Applications for Mobile network Enhanced Logic (CAMEL) allows an advertiser to pay a portion of the airtime cost of a call originated by a mobile subscriber after that subscriber has listened to a recorded advertisement. The combination delivers a text message that associates with a recorded audio advertisement. The text message, which may be referred to later, is stored by the subscriber's handset and may be a transcript of the audio advertisement, provide additional details of the audio advertisement or it may contain an electronic coupon associated with the advertisement.
