> Rich Communication Services – the next-generation messaging protocol succeeding SMS

RCS (Rich Communication Services) is the modern messaging standard replacing SMS with rich media features.

## What is RCS?
Rich Communication Services (RCS) is a messaging protocol developed by the GSMA as the successor to SMS and MMS. It enables features like read receipts, typing indicators, high-resolution image and video sharing, group chat, and interactive cards — all natively in the device's messaging app.

## RCS for business
RCS Business Messaging (RBM) allows brands to send rich, interactive messages to customers — including carousels, suggested actions, and branded sender IDs. Combined with VoIP services, providers can offer a complete [unified communications](/voip-glossary/unified-communications/) package.
