Is there a way to use native call screen for VoIP app on Android when no SIM card is installed?

I'm writing VoIP app using React Native and I'm using React Native CallKeep to handle connection between the app and native call screen.

However, I encountered a problem when there is no SIM card installed on Android device. Then no phone accounts are available in the system and it doesn't allow me to use the native call screen.

It's a limitation of given library, but is there any way to show a native Android call screen (even considering a native Java code) at all? Or it's a limitation of Android API itself?
