How to set up RCS messaging on iPhone

If you’ve ever texted with Android users on your iPhone®, you’ve probably noticed the difference—no read receipts, no typing bubbles, and no high-res photos. But that’s changing with iOS® 18, which introduces support for RCS (Rich Communication Services). This update makes conversations between iPhone and Android smoother, more secure, and more feature-rich.

At Asurion, we help people get the most out of their devices. Whether you're exploring new iOS updates or troubleshooting connection issues, we’ve got you covered. Here’s how to enable RCS on iPhone and improve your messaging experience.

What is RCS messaging?

RCS is the next generation of SMS. It supports features like:

• Typing indicators.
• Read receipts.
• High-quality image and video sharing.
• Better group chats.
• End-to-end encryption (for supported messages).

With iOS® 18 RCS messaging, Apple is bridging the gap between iPhone and Android texting, making messages feel more like iMessage—even across platforms.

How to enable RCS on iPhone

Once you’ve updated to iOS® 18, here’s how to turn on RCS messaging:

1. Open the Settings app.
2. Tap Messages.
3. Scroll down and look for RCS Messaging.
4. Toggle RCS Messaging to On.

How to know if RCS is working

After you enable RCS on iPhone, these signs can help you confirm it’s active:

• You see typing bubbles when texting Android users.

• You can send higher-quality media and see read receipts.
• Group chats between iPhones and Androids feel more seamless.

Keep in mind that both you and the Android user need to have RCS enabled for the full experience.

What if RCS isn’t showing up?

If you don’t see the RCS option in your iPhone settings:

• Check that your carrier supports RCS messaging.
• Restart your phone after updating.
