If you’re like most people, you probably have a voicemail on your Android phone that you use to send calls to people you don’t know. But what if you want to call someone who is already on your phone, but doesn’t have a voicemail? You can do this by using the call forwarding feature of your Android phone. To forward a call to voicemail on your Android phone, first open the call history of the person you want to call. Then go to their contact list and find the number they called from. To forward the call, just press and hold onto the number until it turns into a green light and then release. This will add that person’s voicemail to your call history.
