The document discusses the rise of texting as a preferred communication method, especially among young people. It proposes using Rich Communication Services (RCS) APIs to enable innovative text-based business-to-consumer (B2C) applications and services. WebRTC could also bridge traditional phone networks with web-based applications and allow telcos to expose voice services via APIs. Sample use cases described include customer relationship management, public services, commerce applications, and enabling "new voice" capabilities. The document argues RCS and WebRTC APIs could help telcos engage in the growing texting economy and develop new communication services.
