A joint effort by leading telecom industry players, RCS is proving to be the cornerstone in lending network and vendor-agnostic shape to services, and also rendering them simple to upgrade and enhance since there is no vendor lock-in on proprietary protocols.

Developers today strive to build a communication platform that supports GSMA RCS 1.0/2.0/RCS-e and also refines the message-service network based on converging the traditional and new message services...
