RCS Has Entered the Chat (And Yes, It’s in OneSignal)

Courtney Touchstone -

We’re excited to announce a major leap forward in mobile messaging: OneSignal now supports Rich Communication Services (RCS) Business Messaging.

If you’ve ever felt limited by SMS—plain text, random short codes, no branding or interactivity—RCS is your upgrade. It’s the next generation of mobile messaging, and it’s now available directly inside OneSignal.

What is RCS messaging?

RCS (Rich Communication Services) transforms traditional SMS into visually rich, branded, and interactive conversations. Think of it as messaging that feels more like a mini app than a text. With RCS, you can send:

  • Verified sender messages that display your brand name, logo, and trust badge
  • High-resolution images and videos
  • Suggested replies and action buttons
  • Carousels and rich cards
  • Real-time read receipts and delivery confirmations

And because RCS works over mobile data or Wi-Fi, it removes the character limitations and reliability issues of SMS while still showing up in the user’s default messaging app.

Why this matters for marketers

Modern consumers expect better mobile experiences. RCS delivers just that—and it works.

Brands using RCS have seen:

  • 60% higher conversions compared to SMS
  • 3x more click-throughs
  • Faster time-to-value by combining rich experiences with mobile reach

And now, you can create these experiences from the same place you already manage your push, email, SMS, and in-app messages—OneSignal.

Built for marketers

RCS is powerful, but getting started has traditionally been complicated. We fixed that.

With OneSignal, you get:

  • No-code setup: We handle the brand verification and onboarding process for you
  • Seamless Journey building: Easily add RCS to existing customer journeys or automation flows
  • Built-in analytics: Track delivery, open rates, and clicks—all in one place

How to Get Started

RCS is currently available in the U.S. and select international markets, with broader availability coming soon. If you’re already using OneSignal for SMS or push, adding RCS is simple. If you’re using another provider for SMS, it might be time to make the switch to a provider that has RCS Business Messaging available now.
