Announced on July 25, 2025, by the GSMA, RCS Universal Profile 3.1 brings big updates to Rich Communication Services (RCS). This new standard helps group chat work better for all. It also lets RCS clients get to operator services faster and with less trouble. Because of these changes, you now get a better and smoother time in your RCS Chats. With a universal profile, group chat and RCS feel much easier and more stable for people to use.

Media quality has improved a lot now. You can send voice messages that sound clear. You can share ambient sound clips, and people can hear them well. You can also send high-quality pictures and videos in group chat or one-on-one RCS Chats. This makes RCS chat feel good and new for all of us.

In the next parts, you will see how the new mechanisms help your voice messages sound good. These also keep your connection strong in rcs. You will feel happier every time you chat.

xHE-AAC Codec for High-Quality Voice Messaging

Previously, RCS clients could only play this codec. Now, they can record and play audio, allowing you to send voice notes and ambient sound clips with high quality and small file sizes. This means clear, real-sounding audio without taking up extra space or data.

This upgrade benefits group chats, audio chatbots, and business messaging. GSMA’s Tom van Pelt says, “Voice is the most natural form of talking, and clear sound is key for user happiness.” With xHE-AAC, playback is crisp, noise is reduced, and compression artifacts are minimal.

Efficient compression also means faster sending and lower data use. With this update, RCS voice messaging now matches the audio quality of top messaging apps, making conversations for work or fun sound exactly as they should.

Enhanced Connection Handling with Push Notifications

It now uses push notifications, so your device no longer needs a constant link to operator services. RCS messages now work like popular apps such as WhatsApp and Telegram, offering a more reliable experience. You’ll get all your messages even if you switch between Wi-Fi and mobile data or pass through weak signal areas.

For phone makers and developers, updating RCS clients is key to support the new setup steps.

Push tools on Android and iOS also need proper management. As Google Messages and other apps adopt this, there will be fewer lost messages and lower battery use, improving overall performance.

In low-signal areas or when networks change, push-based delivery ensures messages still arrive. This update helps RCS catch up with other messaging apps, making it smoother and more dependable for everyone.

Building on End-to-End Encryption from Universal Profile 3.0

Universal Profile 3.0 introduced MLS-based end-to-end encryption (E2EE) to keep RCS messages private. Only the sender and receiver can read the message, even if they use different services.

Now, Universal Profile 3.1 takes it further. It raises file size limits, allowing images, documents, and audio to be sent more securely. All files stay encrypted while in transit, ensuring your shared content is kept private.

With E2EE Subspec 2.0, RCS now encrypts messages, media, and receipts from your phone to the recipient’s. This upgrade boosts privacy for group chats, business messaging, and personal conversations.

GSMA’s Dario Betti says, “You can’t skip security in modern messaging.” Universal Profile continues to make RCS chats, audio, and receipts safer, simpler, and more reliable for everyone.
