Once you’ve been granted access to RCS registration in the Twilio console, you’ll have the ability to register RCS test devices for testing traffic and to preview your RCS Sender's look. If you run into issues receiving messages on your Test Devices or after registration, please review following:
Does Your Device Support RCS Business Messaging?
Android Devices
- RCS is supported on Android devices through the Google Messages app by most major mobile carriers.
iPhone Devices
As of iOS 18, Apple supports RCS. Here are key points to remember:
- RCS between people (P2P) is different from RCS Business Messages (A2P). If your device can send RCS messages to others, it might not be able to receive RCS Business Messages.
- Device support also depends on both Apple and your mobile carrier.
How to Check RCS Business Message Support on iOS
To see if your iPhone can receive RCS Business Messages:
- On an iPhone running iOS 18, open the Settings app.
- Navigate to Apps > Messages > RCS Messaging.
- Ensure the option for RCS Business Messages is visible and toggled on.
If you do not see the menu for RCS Messaging, or the toggle for RCS Business Messages, then your carrier has disabled RCS Business Messages on iOS.
