If you’re like most people, you probably have a phone that has a built-in call blocker. This feature helps you keep your calls from ringing when you don’t want them to. But what if you want to call a number that’s in your contacts list but you don’t have the phone number? There are a few ways to block yourself from calling that number on your iPhone. The first way is to go into your settings and select the “call blocker” option. Then, type in the phone number that you want to block and hit “add.” The second way is to go into your contact list and select the " blocked numbers" option. Then, type in the phone number that you want to block and hit “add.” Finally, if all of these methods don’t work for you, there are some third-party apps that can help with this problem.
