If you’re like most people, you probably have a phone that allows you to answer and reject calls. But if you’re iPhone 6 user, there’s a new feature that allows you to block unknown calls. To use this feature, open the Settings app and go to the Call Blocker section. Under the Call Blocker heading, select Unknown Caller. Now, enter the phone number of the person who you want to call and press OK. The call will be blocked and your phone will show an error message saying that it couldn’t find the caller. If you want to continue blocking calls even if they are from someone you know, just add them as a contact in your phone’s contacts book and they’ll be able to call through your blocker.
