Step 2: Add a test device
After your testing registration is approved, add your phone as a test device so you can receive RCS messages from your testing agent.
Note
After you add a test device, the tester invitation is not sent immediately. The system delays activation for at least 120 seconds, and it can take up to 20 minutes for the invitation to arrive. The console shows an approximate activation time. You do not need to wait before adding the device – the system handles the delay automatically.
After you add the test device, AWS End User Messaging sends a tester invitation to the phone number. The invitation comes from an RCS agent called RBM Tester Management and contains two buttons to accept or decline: Make me a tester and Decline. The recipient must tap Make me a tester to complete verification.
Note
On iOS devices (iPhone with iOS 18 or later), the tester invitation may appear in the Unknown Senders folder in the Messages app rather than the main inbox. If you don't see the invitation, check the Unknown Senders folder.
