RCS, or Rich Communication Services, is an advanced messaging protocol designed to replace traditional SMS. It enables enhanced features like high-resolution photo sharing, read receipts, typing indicators, and group chats. Unlike SMS, RCS works over mobile data or Wi-Fi, offering a more dynamic messaging experience. It aims to bring features similar to messaging apps like WhatsApp or iMessage to default texting apps. Supported by many carriers and Android devices, RCS is becoming the new standard for mobile communication.
