Rich Communication Services (RCS) just got a serious boost in usability and quality thanks to the GSMA’s latest release of Universal Profile 3.1. The milestone brings tangible improvements to how RCS works on the ground, especially in the increasingly competitive landscape of mobile messaging where quality and reliability make or break adoption.
In a blog post published earlier today, GSMA’s Tom van Pelt laid out the details of the version 3.1 update, which builds on the foundation of Universal Profile 3.0. The headliners this time around include smarter onboarding and client-server connections, plus significantly better audio messaging.

As Mr. van Pelt explains, the “most impactful” upgrade revolves around connectivity. One of the longstanding challenges with RCS has been inconsistent onboarding and flaky performance under poor network conditions. UP 3.1 addresses this directly by streamlining how RCS clients connect to operator services. It does this via tighter integration with OS-level push notification services and improved client-to-operator interfaces. That may sound like dry backend stuff. However, the result is anything but: expect smoother setup, fewer hiccups, and more reliable messaging, especially when your signal isn’t cooperating.
On the audio front, the GSMA is introducing support for the xHE-AAC codec. That’s a mouthful, but the takeaway is clear. Audio notes and other sound-based messaging features are getting a noticeable bump in clarity and efficiency. Whether you’re sending a quick voice memo, ambient background sounds, or engaging with an audio-enabled chatbot, you’ll get better-sounding results without bloating your data usage. For anyone who relies on voice messaging — a growing segment in global markets — this is an important advancement.
RCS has come a long way since its inception, and momentum is finally building in its favor. According to Google, over a billion RCS messages are sent daily in the US alone. And with cross-platform support rolling out (as even Apple has finally started dipping a toe in the RCS pool) we’re reaching a critical moment for the protocol to prove it can keep up with user expectations.
Universal Profile 3.1 is more than just a technical spec update. It represents a growing consensus across carriers, OEMs, and OS vendors to unify and level up the messaging experience. And with 5G standards now mandating RCS implementation, these updates aren’t just optional — they’re the future.
For hardware and software developers, network operators, and messaging nerds alike, now’s the time to take a fresh look at what RCS can do. Finally more than just SMS’s smarter cousin, it’s evolving into a robust, multimedia-integrating messaging platform in its own right.
