RCS Business Messaging is now live at Telnyx

RBM is here—and it's ready for primetime.

Today, we're launching the Telnyx RCS Business Messaging (RBM) API, giving businesses the power to deliver branded, interactive messaging experiences directly into their customers' native messaging apps. Until now, RCS has been held back by limited support across platforms and carriers. But that’s changing—fast. With Apple announcing RCS support in iOS 18 and global carriers signaling broader readiness, we're entering a new era of rich messaging. Brands can now reach Android and iPhone users alike with a variety of features, including high-resolution media, carousels, tap-to-action buttons, and verified sender trust—all through a single, scalable API built for the future of business messaging.

What's new with Telnyx RCS?

Telnyx RCS is purpose-built for developers who demand flexibility, scalability, and global reach. Our platform is designed from the ground up to make it easy to build, test, and launch RCS Business Messaging flows with minimal friction—whether you're enhancing customer support, marketing, or transactional messaging. With direct-to-carrier infrastructure across global markets, Telnyx ensures your messages are delivered quickly, reliably, and at scale. Plus, we offer developer-friendly tools, clear documentation, and flexible APIs so teams can move fast and create immersive messaging experiences with confidence. With Telnyx RBM, you can expect:

• Verified sender branding with your name, logo, and color palette
• Rich message types including images, videos, carousels, buttons, and location sharing
• Fallback to SMS/MMS for devices that don't support RCS
• Global reach via direct-to-carrier infrastructure
• Built-in compliance with opt-in, opt-out, and encryption best practices

And because RCS works over data, messages can include more interactivity than traditional SMS—think mini web experiences, powered by native UI.

Why now?

For years, RCS was limited by Android-only support. That changed with Apple’s iOS 18 announcement. Starting in late 2024, iPhones will support RCS, finally closing the interoperability gap and making RCS a viable replacement for plain-text business messaging.

Add to that the GSMA’s roadmap for interoperable end-to-end encryption, and the market is signaling that RCS is no longer a future bet—it’s a current opportunity.

RCS in action

With RCS Business Messaging, businesses can go far beyond plain text to deliver interactive, branded experiences directly within their customers’ native messaging apps—regardless of your use case. No more linking out to mobile websites or relying solely on SMS—RCS brings the functionality of an app into the message itself. Whether you're engaging customers post-purchase, launching a new product campaign, or automating support with AI, RCS opens the door to richer, more responsive conversations that drive results:

• Send branded order updates with buttons to track, reschedule, or reorder
• Deliver rich promotions with swipeable product carousels
• Power AI chatbot flows directly in the messaging app
• Use fallback-to-SMS logic for full reach without campaign drop-off

Built for scale

Telnyx delivers RCS over the same infrastructure that powers our voice, messaging and AI products. That means you get ultra-low latency, high deliverability, and full API control—plus transparent pricing with no black-box markups.
