Get ready for a significant upgrade to your smartphone’s default messaging experience! The latest evolution of Rich Communication Services (RCS), known as Universal Profile 4.0, is set to revolutionize how we communicate, bringing native video calls and a host of other exciting RCS 4.0 features directly into your chat app.
This update promises to make messaging more interactive and feature-rich, bridging the gap between traditional SMS and popular third-party chat applications. The GSMA, which oversees RCS development, has finalized this comprehensive upgrade, pushing the standard to new heights.

What’s New in RCS Universal Profile 4.0?
The Universal Profile 4.0 introduces several key enhancements designed to make your messaging more powerful and seamless. These improvements aim to provide a more unified communication experience across different devices and platforms.
Native Video Calls Arrive
- Messaging-Initiated Video Calls (MIVC): The standout feature of RCS 4.0 is the ability to start video calls directly within your messaging app. You won’t need to switch to a separate app like Google Meet or FaceTime to go from a text conversation to a face-to-face chat.
- Group Call Flexibility: This feature also supports group video calls, allowing participants to join an ongoing conversation even if they missed the initial notification. This ensures continuity and convenience for everyone involved.
Enhanced Messaging Features
Beyond video calls, RCS 4.0 brings a suite of improvements to the core messaging experience, making your chats more expressive and media-rich.
- Rich Text Formatting: Finally, you can easily add bold, italics, or strikethrough to your messages. This allows for more emphasis and clarity in your text conversations.
- Higher Quality Media Sharing: Sending photos, videos, and audio will be significantly better. Devices will now intelligently identify supported media formats between conversation partners, ensuring your content is shared at the highest possible quality without excessive compression.
Business Messaging Upgrades
RCS 4.0 also includes valuable updates for business messaging, enabling more engaging and interactive interactions between companies and their customers.
- Embedded Streaming Videos: Businesses can now embed streaming videos directly into Rich Cards, eliminating the need for users to download content to view it.
- Improved Link Control: Businesses will have greater control over how links open, allowing users to stay within the messaging app for quick actions or be directed to a dedicated external app for more complex tasks like payments.
Why It Matters
The introduction of RCS 4.0 is a significant step forward for smartphone communication. For years, users have relied on third-party apps for advanced features like high-quality media sharing, read receipts, and group chat capabilities. RCS aims to bring these modern features directly to your phone’s native messaging app.
With Apple’s adoption of RCS for iPhones in late 2024, the playing field for cross-platform messaging has already improved. RCS 4.0 further enhances this interoperability, promising a more consistent and feature-rich experience whether you’re chatting with an Android or iPhone user. It reduces the need to switch between multiple apps, streamlining your digital conversations.
Looking Ahead
While the GSMA has officially finalized RCS Universal Profile 4.0, the actual rollout to devices will depend on mobile carriers, device manufacturers, and messaging app developers like Google Messages. Widespread adoption may take some time, possibly rolling out gradually through late 2026 or into early 2027.
However, the finalization of this standard lays the groundwork for a future where your default messaging app is a powerful, all-in-one communication hub, capable of much more than just basic texts.
Conclusion
RCS Universal Profile 4.0 marks a pivotal moment for mobile messaging, bringing native video calls and a suite of rich communication tools to the forefront. These advancements promise a more integrated, expressive, and convenient way to connect with friends, family, and businesses, making your smartphone’s messaging app more capable than ever before.
