Do Customers Need an App for RCS?

No—customers do not need to download an app. RCS works in native messaging apps (Google Messages on Android; Messages on iOS 18+), with automatic SMS fallback when RCS isn't available.

How RCS Works on Existing Phones

RCS is built into the messaging apps that come pre-installed on modern phones:

Android Devices

• Google Messages (pre-installed on most Android phones)
• Samsung Messages (pre-installed on Samsung devices)
• Carrier messaging apps on some networks

If your customer has a modern Android phone, RCS likely already works—they just don't know it.

iPhone (iOS 18+)

• Apple's iOS 18 added RCS support to the Messages app
• iPhone users see RCS messages with rich features
• Older iOS versions fall back to SMS automatically

Other Devices

• Feature phones: Fall back to SMS
• Older smartphones without RCS: Fall back to SMS

The Coverage Reality

As of 2024:

• 75%+ of Android phones have RCS support enabled
• iOS 18+ users support RCS in Messages app
• 95%+ of US smartphone users can receive RCS or SMS messages

That means virtually all your customers can be reached.

What Customers Actually Experience

From the customer's perspective, RCS messages look like any other text message. They tap to read, see your logo and brand colors, view images and videos inline, and tap buttons to interact. No friction, no learning curve.

The Automatic Fallback Magic

Here's the best part: you don't have to manage device lists or worry about coverage. The platform automatically:

1. Detects if the recipient's device supports RCS
2. Sends a rich RCS message if supported
3. Falls back to SMS if RCS isn't available
4. Tracks which path each message took

Your analytics show you the breakdown, so you can see your RCS vs SMS fallback rates and optimize accordingly.

What About Users Who Don't Want RCS?

Some customers prefer plain SMS. That's fine—your messages will fall back to SMS for them automatically. They still get your message, just without the rich features.

Geographic Variations

RCS support varies by country and carrier:

• United States: Excellent support across major carriers
• Europe: Strong support in UK, Germany, France, Spain
• India: Widespread adoption
• Asia Pacific: Growing in Japan, Australia, Singapore
• Latin America: Expanding in Brazil, Mexico

For regions with limited RCS support, the platform handles fallback seamlessly.

What This Means for Your Strategy

The fact that RCS works on existing apps means:

• Zero customer friction: No download barriers
• Higher reach: Works on devices customers already use
• Better engagement: Customers get rich experiences without changing behavior
• Universal delivery: SMS fallback ensures no message is lost

The Bottom Line

You can launch RCS campaigns without worrying about app adoption. Your customers will see your messages in their existing messaging app, with rich features where supported and plain SMS where not. Everyone gets your message.
