Do My Customers Need to Download an App?
No app download required for most users. RCS works natively in Google Messages (Android) and is built into the iOS Messages app starting with iOS 18. If a customer doesn't have RCS, messages automatically fall back to SMS—so you never lose a message.
Key Points
- No app download required
- Built into Google Messages on Android
- Built into iOS Messages starting iOS 18
- Automatic SMS fallback for unsupported devices
- Universal coverage without user friction
Do Customers Need an App for RCS?
This is one of the most common questions I get, and the answer is almost always good news: no app download required.
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:
- Detects if the recipient's device supports RCS
- Sends a rich RCS message if supported
- Falls back to SMS if RCS isn't available
- 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.
