Silence the Unknown: How to Effectively Block Anonymous Calls on Your Phone
Are you tired of your phone ringing incessantly, only to find an anonymous caller on the other end? Anonymous calls, often masking telemarketers, scammers, or simply unwanted contacts, can be a significant source of annoyance and even anxiety. Thankfully, there are several effective strategies you can employ to block these calls and regain control of your phone’s peace and quiet. This comprehensive guide will walk you through various methods, catering to different phone types and service providers, ensuring you find the solution that works best for you.
## Understanding Anonymous Calls
Before diving into the methods, let’s clarify what constitutes an anonymous call. Typically, an anonymous call is one where the caller’s information is intentionally hidden or unavailable. This is often achieved through:
* **Caller ID Blocking:** The caller actively blocks their number from being displayed on your phone.
* **Private Number Settings:** Similar to caller ID blocking, the caller designates their number as private.
* **Unassigned Numbers:** Calls originating from numbers not assigned to a specific user or entity (often used by telemarketers).
These calls often appear as “Unknown Caller,” “Private Number,” “Blocked,” or simply a blank space in your caller ID.
## Blocking Anonymous Calls: A Step-by-Step Guide
Here are several methods you can use to block anonymous calls, ranging from simple phone settings to more advanced techniques:
### 1. Utilizing Your Phone’s Built-in Blocking Features
Most modern smartphones offer built-in features to block unwanted calls, including anonymous ones. Here’s how to access and utilize these features:
#### For iPhones (iOS):
* **Silence Unknown Callers:** This feature, introduced in iOS 13, automatically silences calls from numbers that are not in your contacts list. These calls are sent directly to voicemail, but you will still see them in your recent calls list.
* **How to Enable:**
1. Open the **Settings** app.
2. Scroll down and tap **Phone**.
3. Scroll down to **Silence Unknown Callers** and toggle the switch to the **On** position (green).
* **Important Considerations:** This feature might inadvertently silence calls from legitimate contacts who are not in your phone book, such as doctors’ offices or delivery services. Be sure to check your voicemail regularly to avoid missing important calls.
* **Manually Blocking Numbers:** You can manually block specific numbers that appear as “Unknown Caller” after they have called you (though this only works if *some* identifying info is shown on the caller ID, even if it’s just an area code).
* **How to Block:**
1. Open the **Phone** app.
2. Tap on the **Recents** tab.
3. Find the “Unknown Caller” entry you want to block.
4. Tap the **(i)** icon next to the number.
5. Scroll down and tap **Block this Caller**.
6. Confirm by tapping **Block Contact**.
#### For Android Phones:
Android’s approach to blocking calls varies slightly depending on the manufacturer and Android version. However, most Android phones offer similar functionalities:
* **Built-in Blocking Feature:** Most Android phones have a built-in call blocking feature. Here’s a general guide (specific steps may vary based on your phone model):
* **How to Block (General Steps):**
1. Open the **Phone** app.
2. Tap on the **Recents** tab (or **Call History**).
3. Find the “Unknown Caller” entry you want to block.
4. Tap and hold on the number.
5. Select **Block/report spam** or a similar option from the menu that appears.
6. You may be given the option to report the number as spam. Check the box if appropriate and then tap **Block**.
* **Using Third-Party Apps (see section 3 below):** If your phone doesn’t have a robust built-in blocking feature, consider using a third-party call blocking app.
### 2. Contacting Your Mobile Carrier
Mobile carriers often provide services or features that can help block unwanted calls, including anonymous ones. Contact your carrier’s customer support or visit their website to explore the following options:
* **Anonymous Call Rejection:** Some carriers offer a service that automatically rejects calls from numbers that are blocked or unavailable. This service may require a subscription fee.
* **How to Inquire:** Contact your carrier’s customer service department and ask about “anonymous call rejection” or a similar service. They will be able to provide information on availability, pricing, and how to activate the service.
* **Call Filtering Services:** Many carriers offer call filtering services that use advanced algorithms to identify and block potential spam and robocalls. These services often include the ability to block anonymous calls as well.
* **Examples:** T-Mobile Scam Shield, Verizon Call Filter, AT&T Call Protect.
* **How to Activate:** Download the carrier’s call filtering app from the App Store or Google Play Store and follow the instructions to activate the service. Some services may be automatically enabled for certain plans.
* **Number Change:** As a last resort, if you are receiving an overwhelming number of anonymous calls, you may consider changing your phone number. This is a more drastic measure, but it can be effective in stopping unwanted calls.
* **Considerations:** Changing your number will require you to update your contact information with all your important contacts, businesses, and services. It can also be disruptive to your daily routine.
### 3. Utilizing Third-Party Call Blocking Apps
Numerous third-party apps are available on the App Store and Google Play Store that can help block spam calls, robocalls, and anonymous calls. These apps often use extensive databases and advanced algorithms to identify and block unwanted callers.
* **Popular Call Blocking Apps:**
* **Truecaller:** A popular app that identifies and blocks spam calls, as well as providing caller ID information. It has a large community-based database of reported spam numbers.
* **Hiya:** Another well-regarded app that offers call blocking, caller ID, and spam detection features. It also includes a number lookup feature that allows you to identify unknown numbers.
* **Nomorobo:** A specialized app designed to block robocalls. It uses a ring-once-and-hang-up technique to identify and block robocalls before they reach you.
* **RoboKiller:** An aggressive call blocking app that uses answer bots to engage with and waste the time of spammers and robocallers. It also provides call blocking and spam detection features.
* **How to Choose an App:**
* **Read Reviews:** Check app reviews on the App Store or Google Play Store to get an idea of the app’s effectiveness and user experience.
* **Consider Pricing:** Some call blocking apps are free, while others offer premium features for a subscription fee. Choose an app that fits your budget and needs.
* **Privacy Considerations:** Be sure to read the app’s privacy policy to understand how it collects and uses your data. Choose an app that respects your privacy and does not share your data with third parties without your consent.
* **How to Use a Call Blocking App (General Steps):**
1. **Download and Install:** Download the app from the App Store or Google Play Store and install it on your phone.
2. **Grant Permissions:** Grant the app the necessary permissions, such as access to your contacts, phone calls, and call history.
3. **Configure Settings:** Configure the app’s settings to block spam calls, robocalls, and anonymous calls. You may be able to customize the blocking behavior, such as sending calls directly to voicemail or blocking them entirely.
4. **Update Database:** Regularly update the app’s database to ensure that it has the latest information on spam numbers.
### 4. Using a VoIP Phone System’s Blocking Features
If you use a VoIP (Voice over Internet Protocol) phone system at home or for your business, you likely have access to more advanced call blocking features than traditional landlines or mobile phones.
* **VoIP Provider’s Features:** Most VoIP providers offer a range of call management features, including:
* **Blacklisting:** Manually add specific numbers to a blacklist to prevent them from calling you.
* **Anonymous Call Rejection:** Automatically reject calls from numbers with blocked or unavailable caller ID.

### 5. Contacting Law Enforcement (in Extreme Cases)
If you are receiving harassing or threatening anonymous calls, you may consider contacting law enforcement. While they may not be able to track down the caller in every case, they can investigate the situation and take action if necessary.
* **When to Contact Law Enforcement:**
* **Threats of Violence:** If you receive calls that threaten you or your family with violence.
* **Harassment:** If you are repeatedly harassed by anonymous callers.

## Tips for Reducing Anonymous Calls
In addition to blocking anonymous calls, here are some tips to help reduce the number of unwanted calls you receive in the first place:
* **Don’t Answer Unknown Numbers:** If you don’t recognize the number, let the call go to voicemail. If it’s important, the caller will leave a message.
* **Don’t Give Out Your Number Unnecessarily:** Be cautious about giving out your phone number online or to businesses that you don’t trust.
* **Register on the National Do Not Call Registry:** While this may not stop all unwanted calls, it can help reduce the number of telemarketing calls you receive.
* **How to Register:** Visit donotcall.gov or call 1-888-382-1222 (TTY: 1-866-290-4236).
* **Be Wary of Online Forms:** Avoid filling out online forms that require your phone number unless you are certain that the website is legitimate.
* **Opt Out of Marketing Lists:** Contact businesses that you have previously given your phone number to and ask to be removed from their marketing lists.
