This wikiHow teaches you how to block calls from unknown numbers on both iPhone and Android. You can do this by using Do Not Disturb on iPhone, or changing calling settings on Android if you're using a Samsung phone. If you're not using a Samsung phone, you can download an app called Should I Answer? to block unknown calls on Android. Unfortunately, there are no apps or settings on iPhone to block private, unknown, or restrict incoming calls.
