Is There a Way to Block Numbers on My Motorola Razr Phone?

You can block incoming calls from unwanted callers to your Motorola Razr mobile phone by adjusting your security settings. Adjusting the settings allows you to only accept calls from people who are saved to your Motorola Razr's address book. When a call comes in from someone not in your address book, the phone does not even ring. The built-in feature is free to use, and you can enable or disable it at any time.
