RCS, or Rich Communication Services, is a modern messaging protocol that enhances the traditional SMS experience by providing users with a more dynamic and interactive way to communicate. Unlike SMS, which is limited to basic text and media, RCS allows for features such as group chats, high-quality images and videos, read receipts, and even file sharing. With RCS, users can also see when someone is typing, making conversations feel more natural and fluid. This innovative technology is quickly becoming the new standard for mobile messaging, offering a more engaging and seamless way to connect with others.
