Android Community July 12, 2021 Even though Rich Communication Services has been touted as the next generation SMS, it’s taking a while for all users to have access to it. To be able to run it on your phone, your network, OS, and your messaging app have to support it through an API. Google has already bypassed the carriers by adding an RCS API for Google Messages but it’s only available for that app. Now it looks like in the latest update to the app, 3rd party apps can request for the RCS API but it seems limited to Samsung apps only.
