有別於過去單一運營商透過 App 方式支援 Rich Communications Services 效果不彰。Google 收購了 Jibe[1] 之後，已經將 RCS[2] 整合入 Google Messenger，並預載在 Pixel 品牌手機上。透過 Android 平台來推展 RCS 支援與標準[4][5]，Sprint[2][3] 會是第一家開始搭售 Google RCS 客戶端的電信運營商。不想內建 Google Messenger 的手機公司，像是 Samsung[6] 則是透過收購 NewNet 的方式取得技術。
目前 RCS Universal profile 開放規格[7]只是出第一階段規格書，包含基本的通訊協議規格，2017 年第二季會發出下一階段規格書，將會包含 Messaging as a Platform, APIs, plug-in integration 等規格。
RCS Universal profile 是基於 RCS 5.3 定義，基本上補強了協議擴充功能與互通性。但是 3GPP RCS 規格與 China Mobile 的 NGCC (Next-Generation Converged Communication)[8]，現階段有很大的差異性。
Universal Profile 中偏好的協議實踐方法與中國移動不同，但目前全球最大 RCS 網路系統中是由中興通訊為中國移動建制，已開始 App 內部試商用階段，如果未來兩份通訊協議規格無法統一互通，那麼中國市場可能會變成擁有強大影響力的孤立市場。
