Restricted calls may pose a significant challenge to personal privacy. Hence, it would be helpful to learn actionable methods to combat it. This article delves into the intricacies of restricted calls, outlining the motives behind them and offering practical solutions for blocking them on both Android and iPhone devices. 

Understanding Restricted Calls

When the caller hides their number, the call becomes restricted. They do this by dialing *67 before making a call. This makes their phone number not show up on your phone. It appears as “Private,” “Anonymous,” or “Restricted.” People do this for many reasons, like wanting privacy or trying to surprise someone.

Knowing about restricted calls helps you handle them better. You can decide if you want to answer these hidden number calls or block them for good. Some might be from friends doing a prank, but others could be spam or scam calls trying to trick you. Being aware lets you protect your privacy and security on your smartphone, whether it’s an Android device or iPhone.

Why Block Restricted Calls?

Blocking restricted calls keeps your phone secure from unknown callers. It also protects your privacy by stopping unwanted calls from reaching you.

Security Reasons

Calls from restricted numbers can hide unwanted callers, like telemarketers or scammers, threatening your security. These callers often use hidden numbers to avoid identification and accountability. By blocking restricted calls, you protect yourself from potential frauds and scams that could harm you financially or emotionally.

Protecting your personal information becomes easier when you block these restricted calls on your smartphone. Scammers find it harder to reach you with their deceptive schemes. This simple step keeps your identity safer and reduces the risk of falling victim to phone-based scams, which are becoming more common today.

Privacy Concerns

Privacy concerns are at the heart of why many choose to block restricted calls. These calls hide the caller’s identity, making it hard to know who is trying to reach you. This lack of transparency can lead to unwanted intrusions into your personal life, including harassment or scam attempts. Blocking these numbers protects your privacy and stops these anonymous callers from breaching your personal space. 

Employing features like caller ID blocking on smartphones helps maintain your privacy and ensures that only approved contacts can get in touch with you directly. Making use of such security measures keeps your private information safe and wards off unwelcome disruptions caused by hidden callers.

How to Block Restricted Calls on Android

To block restricted calls on Android, users can explore their phone’s built-in settings. They might also consider downloading a call-blocking app from Google Play for added protection.

Using Built-in Features

Smartphones come loaded with features to make life easier. One such convenience is the ability to block restricted calls directly from your device. Here’s how you can use built-in features on your smartphone to block those unwanted calls:

  1. Open your phone app: Start by going into the phone application, where you usually see your call history.
  2. Find Call History: Look for recent calls or call history in the app. This is where you’ll find the numbers that called you.
  3. Select the restricted call: Tap on the call you wish to block. Restricted calls might show up as “Unknown” or “Private.”
  4. Tap on the information icon: Look for an “i” icon or similar to get more details about the call.
  5. Choose to block: There should be an option here to block or restrict this caller. Click it.
  6. Confirm your choice: Your phone might ask if you’re sure about blocking this number. Confirm your decision.

For Android phones, these steps will prevent that number from interrupting you again. Most Android devices have a straightforward way of doing this through their security settings or call settings menu. On iPhones, these steps are just as simple and keep those restricted numbers away without much hassle.

Remember, after blocking a restricted call, review your blocked numbers list occasionally to ensure no important contacts are accidentally blocked.

Employing Call Blocking Apps

Using call blocking apps on your smartphone is another foresightful option. These apps help you manage unwanted calls efficiently.

  1. Download a reputable call blocking app from the app store. Look for apps with high ratings and positive reviews to ensure reliability.
  2. Install the app and grant it the necessary permissions. This may include access to your contacts, call history, and the ability to block calls.
  3. Set up your preferences within the app. Some apps allow you to create blacklists of numbers you wish never to hear from again.
  4. Explore features for detecting spam or scam calls. Many call blocking apps have databases of known spam numbers and can automatically block them for you.
  5. Take advantage of community reports within the app. Users often share insights on new telemarketing numbers or robocalls, keeping the database updated.
  6. Review blocked calls in the app’s dashboard. This feature lets you see which numbers were blocked and decide if you need to make adjustments to your blacklist.
  7. Utilize parental control options if available. These can help protect younger family members from receiving inappropriate calls or messages.
  8. Check for integration with social media platforms or messaging services for comprehensive protection across all communication channels.
  9. Update the app regularly to benefit from improved features and an expanded database of known spam callers.

Employing a call blocking app offers an additional layer of security against unwanted, restricted calls, keeping your phone experience peaceful and privacy intact.
