To make and receive calls and text messages on your Windows 10 laptop without a physical Android device, you would typically need to use the "Your Phone" app, which integrates with Android devices. However, since you do not have a working Android phone, this integration will not be possible.
Currently, there is no alternative method to set up the "Your Phone" app or similar functionality without having access to an Android device for the initial configuration. You might consider using other communication tools such as Microsoft Teams or VoIP services that allow you to make calls directly from your laptop, but these would not replicate the SMS functionality provided by the "Your Phone" app without a linked mobile device.
If you are looking for alternatives, you might want to explore using services like Skype or Microsoft Teams for calls, but again, these will not provide SMS capabilities without a mobile device.
