How the simulator works
- Install the Android APK on a device you control.
- Enter a fictional or consented caller identity.
- Choose the countdown, ringtone, vibration and call-screen theme.
- Run a short private test before relying on a delayed simulation.
The app renders the scene locally. It does not dial the displayed number or place a carrier call.
Choose the right guide
Before the first simulation
- Confirm notification and ringtone volume on the same device.
- Test whether the screen can appear while the phone is locked.
- Check battery restrictions if the countdown runs in the background.
- Keep caller names and scenario details fictional or consented.

Does the APK include SMS demos?
Yes. Call Simulator Assistant includes local call, SMS-style and call-record simulation features.
