Yes, Google supports RCS (Rich Communication Services) and has been working to promote its adoption as a standard messaging protocol. Google has developed its own RCS client, called Google Messages, which is pre-installed on many Android devices. Google Messages supports RCS messaging and offers features such as read receipts, typing indicators, and the ability to send high-quality photos and videos.
In addition to developing Google Messages, Google has been working with mobile network operators and device manufacturers to promote the adoption of RCS as a global messaging standard. In 2018, Google launched the RCS Business Messaging program, which enables businesses to send RCS messages to their customers in a more interactive and engaging way. The program is designed to help businesses better connect with their customers and provide a more seamless and engaging messaging experience.
While there are still some challenges that need to be addressed before RCS can become a true global standard for messaging, Google's support is helping to drive the adoption of RCS and improve the messaging experience for users.
