RCS (Rich Communication Services) is a communication protocol designed to replace SMS and MMS, offering a more modern and feature-rich messaging experience, primarily on mobile phones

. It was developed and defined by the GSM Association (GSMA)

. RCS brings features like high-resolution image and video support, file sharing, typing indicators, and improved group chat functionality

. Here's a breakdown of what RCS offers:

• Enhanced Features RCS delivers features similar to those found in popular IP-based communication services, such as group chat, high-quality media sharing, read receipts, and location sharing

• Rich Media Support Unlike SMS, which has character limits and limited multimedia support, RCS allows you to send high-resolution images, videos, and audio messages without strict file size limits

• Interactive Capabilities RCS includes features like read receipts, typing indicators, and the ability to manage group chats easily

. It also supports interactive elements within messages, such as buttons for booking appointments or confirming orders

• Cross-Platform Communication With Apple's adoption of RCS in iOS 18, users can enjoy features like high-resolution media sharing and typing indicators when messaging between Android and iOS devices

• Integration RCS is integrated into many Android devices, making it easier to use

. Google Messages uses RCS and provides it through their Jibe backend, even without carrier support, while still connecting to the global RCS network

• Security RCS offers end-to-end encryption for secure communication when messaging other users who also have RCS enabled
