In 2025, communication has evolved—and so has mobile messaging. Traditional SMS is no longer enough for brands or consumers who expect fast, interactive, and secure conversations. That’s where RCS chat means a whole new era of messaging. RCS, or RCS full form: Rich Communication Services, is a modern messaging protocol designed to replace outdated SMS technology. Unlike SMS, which limits you to basic text and minimal media, RCS delivers rich, engaging, app-like experiences right in your phone’s native messaging app.
