what is rcs chat on text messages

RCS, or Rich Communication Services, is a modern industry standard for messaging that provides an upgraded, rich messaging experience compared to traditional SMS or MMS. It offers features such as showing when someone is typing, read receipts, high-quality media sharing, and better security. RCS messages are sent with the RCS protocol over Wi-Fi and mobile data, and they are provided by Google or mobile carriers. When RCS chats are turned on, users can send messages over Wi-Fi and use other features. RCS is designed to upgrade SMS for modern systems and needs, offering more options, images, videos, and better security. It is considered a versatile, secure option for modern messaging and is intended to replace SMS as the standard messaging protocol in the future. RCS works with the native messaging app built into Android devices, and it is available for Android phones. However, it is important to note that RCS requires data to work, and it may not completely replace SMS, as SMS can still serve as a fallback in certain situations.
