How to Block Unknown Callers

This wikiHow teaches you how to block calls from anonymous numbers on your iPhone or Android. You can do this by using Do Not Disturb on your iPhone, or by changing call settings on your Android if you have a Samsung phone. If you don't have a Samsung phone, you can download an app called "Should I Answer?" to block incoming unknown calls on Android. Unfortunately, there isn't an app or a setting available on iPhone that will only block incoming private, unknown, or restricted calls.

• If you live in the United States of America, you can register your phone number with the Do Not Call registry by going to http://ift.tt/numkdw, clicking REGISTER HERE, and entering your phone number and a working email address. This will require telemarketers and spammers to remove your phone number from their call lists within 31 days.
