Blocking No Caller ID Calls on iPhone: A Step-by-Step Guide

Tired of getting calls from unknown numbers or No Caller ID on your iPhone? It’s time to take control of your phone and block those pesky calls once and for all. With just a few simple steps, you can say goodbye to unwanted interruptions and enjoy some peace and quiet. Let’s dive into how to get this done.

Step by Step Tutorial on Blocking No Caller ID Calls on iPhone

Before we get into the nitty-gritty, let’s talk about what we’re trying to achieve here. By following these steps, you’ll be setting up your iPhone to automatically silence calls from numbers that are not in your contacts list, which includes those No Caller ID calls.

Step 1: Go to Settings

Open your iPhone’s Settings app to get started.

In the Settings app, you’ll find a variety of options to customize your iPhone experience. For this task, we’ll be focusing on the Phone settings.

Step 2: Tap on ‘Phone’

Scroll down and select the ‘Phone’ option to access call settings.

In the Phone settings, you’ll find options related to calls, voicemail, and your SIM card, but we’re looking for the call silencing and blocking features.

Step 3: Select ‘Silence Unknown Callers’

Look for the ‘Silence Unknown Callers’ option and tap on it.

This feature is a powerful tool in your iPhone’s arsenal against unwanted calls. When enabled, calls from unknown numbers will be silenced, sent to voicemail, and displayed in the Recents list.

Step 4: Toggle the switch to ON

Flip the switch next to ‘Silence Unknown Callers’ to the ON position.

When the switch is green, you’ll know the feature is active. Now, any call from a number that’s not in your contacts will be silenced automatically.

After completing these steps, calls from No Caller ID numbers will be silenced, and you won’t be bothered by them. However, remember that this means any legitimate call from a number not saved in your contacts will also be silenced. Keep an eye on your voicemail for any important missed calls.

Tips for Blocking No Caller ID Calls on iPhone

  • Make sure your important contacts are saved in your address book to avoid missing their calls.
  • Consider using third-party call blocking apps for more advanced features and control over incoming calls.
  • Regularly check your voicemail, as silenced calls will be sent there.
  • If you’re expecting an important call from an unknown number, you can temporarily disable the feature.
  • Remember that this feature only silences calls; it doesn’t prevent the caller from leaving a voicemail.
