Google is launching, the Rich Communication Service (RCS) through Google Messages app, the 9th Google messaging app following Google Talk, Google Buzz, Google Voice, Hangouts, Spaces, Google+ Messenger, Allo and Hangouts Chat. Users of the Google application will finally see a “Make more action with messages” notification, and they will be able to “allow chat”, or RCS. Google said it will enable this feature for US users “in the next few weeks” and that the service “will be widely available in the US by the end of 2019.” As a 2019 messaging standard, RCS is quite a foot, but keep in mind that it is an alternative to SMS – the specification is set by the operators of GSMA members. The RCS upgrades carrier messaging using features such as status information, typing indicators, location sharing, group messaging, longer messages, and improved media support. These are all the features of all the instant messaging applications you want to get in the recent era, but as an operator-integrated SMS alternative, these basics don’t exist yet.
The service is not end to end encrypted, so Google can read your message. It treats your phone number as primary identity, so operators do not have to worry about your identity. Again, this makes sense when the operator designs the specification. They hope to use themselves as the center of communication life, and clear words provide them with better opportunities for profit. Why do non-operators use this standard?
Because RCS is very basic, it is not a good standard for messaging services. The only powerful feature of RCS comes from your carrier, which will immediately upgrade the benchmark messaging service provided by it (at least for new phones). The functionality of the RCS comes from the default value. However, Google’s RCS version is not the default version. Just need to download the Messages app by Google to use it, and is not the default SMS app on most phones. The app doesn’t need to be available with Play Stores such as Google Maps, Gmail, Search and other Google apps, so OEMs do not offer it at all. Instead, they chose their own messaging application.
