An RCS message is a type of advanced text message sent using the Rich Communication Services (RCS) protocol, designed to replace traditional SMS and MMS messaging with richer, more interactive features. Unlike SMS, which is limited to plain text and 160 characters, and MMS, which supports basic multimedia, RCS messages enable high-resolution images, videos, GIFs, audio, and longer text messages without segmentation. They also support interactive elements such as buttons, carousels, suggested replies, and call-to-action features, enhancing user engagement directly within the native messaging app on smartphones without needing third-party apps

. Key features of RCS messages include:

• Multimedia support with high-quality photos, videos, and GIFs.
• Interactive content like scrollable carousels, quick replies, and action buttons.
• Company branding and verification, allowing businesses to attach logos and verified badges.
• Read receipts and typing indicators, providing real-time feedback on message status.
• Group chat capabilities and real-time location sharing.
• Support for secure in-app payments in some implementations.
• Messages are sent over mobile data or Wi-Fi, improving delivery flexibility.
• Encryption support, with Google Messages offering end-to-end encryption for RCS messages

RCS messages are exchanged directly through the phone’s native messaging app, making the experience seamless for users and providing businesses a powerful channel to communicate interactively with customers on a platform they already trust
