Hello PH - RCS, sometimes referred to as SMS 2.0, is the next generation of messaging being deployed by the mobile network operators. RCS allows for two-way conversations utilizing a rich media experience including actions, buttons, quick replies, carousels and rich content. This technology turns the native messaging client on your mobile device into a host of many applications and the next development frontier. To date, RCS is only available on a limited number of Android devices and mobile network operators so our goal was to close this gap. With the nativeMsg RCS Fallback experience, brands and businesses can deploy RCS style experiences on any smartphone including Apple iOS devices today. Eventually, true RCS will have adequate coverage, but in the meantime we are looking for early participants to launch RCS and our new Fallback experience.
