The Signal Secure Message feature only works when you chat with someone who also uses the app. You will see the text input field reading “Signal message” before you type anything. Also, the send button will be blue with a closed lock. These indicators also mean that you are having private communication with a Signal user.

If you wish to send an insecure Signal message on Android, i.e., a normal SMS, you can do that by tapping and long-pressing the send button and switching to “insecure messages.”
