🚫 Turn Off iMessage

To ensure messages are sent over the cellular network (SMS/MMS) and not via Apple's iMessage service, disable iMessage during testing:

1. Open Settings.
2. Go to Messages.
3. Toggle iMessage → OFF

⚠️ Disabling iMessage is essential to prevent messages from being routed through Apple's internet-based service, which may interfere with protocol-level SMS/MMS test validation.
