Ultimate Guide: How to Stop Unwanted Calls on Cell Phones

Unwanted calls on cell phones can disrupt your peace and invade your privacy. Whether you’re dealing with telemarketers, spam callers, or persistent harassers, it’s essential to know how to stop these unwanted calls and regain control over your phone. In this ultimate guide, we will provide you with comprehensive strategies, tips, and tools to effectively put an end to unwanted calls on your cell phone.

Understanding Unwanted Calls

Unwanted calls come in various forms, including robocalls, telemarketing calls, and scam calls. Robocalls are automated calls generated by computerized systems, while telemarketing calls are typically promotional calls from businesses. Scam calls aim to deceive and defraud unsuspecting individuals. Understanding the different types of unwanted calls and their motives will help you tackle them more effectively.

Built-In Features for Call Blocking

Most cell phones offer built-in call-blocking features that can help you filter out unwanted calls. On iOS devices, you can utilize the “Silence Unknown Callers” feature to silence calls from unknown numbers. Android devices provide options like “Block Numbers” or “Call Blocking” within the phone settings.

Here are step-by-step instructions on how to enable and customize these features on your specific device:

For iOS:

  • Go to Settings on your iPhone.
  • Scroll down and tap on “Phone.”
  • Select “Silence Unknown Callers” and toggle the switch to enable it.
  • This feature will silence calls from numbers not in your contacts, recent outgoing calls, or Siri Suggestions.

For Android:

  • Open the Phone app on your Android device.
  • Tap the three-dot menu icon and select “Settings” or “Call settings.”
  • Look for “Block numbers” or “Call blocking” options.
  • Follow the on-screen instructions to add numbers to the block list or enable call blocking.

Third-Party Call Blocking Apps

In addition to built-in features, you can explore third-party call blocking apps that offer advanced call-filtering capabilities. These apps provide features like caller ID, spam call detection, and blocking options.

Here are some popular apps to consider:

  • Truecaller: Truecaller is a widely used app that identifies and blocks spam calls. It also provides a community-based spam list to keep you updated on the latest spam numbers reported by other users.
  • Hiya: Hiya is another app that offers caller ID, call blocking, and spam detection features. It integrates with the phone’s built-in dialer and provides real-time alerts for incoming spam calls.
  • Nomorobo: Nomorobo is specifically designed to block robocalls and telemarketing calls. It uses a vast database of known spam numbers to keep unwanted calls at bay.

Please note that the availability and compatibility of these apps may vary based on your device and location. We recommend exploring the respective app stores for more information, user ratings, and compatibility with your device.

Tips for Handling Persistent Callers

Dealing with persistent callers can be challenging, but there are strategies you can employ to protect yourself.

Follow these tips to handle unwanted calls effectively:

  1. Document Details: Keep a record of each unwanted call, including the date, time, and caller ID information. This documentation will be helpful if you need to report the calls to the authorities or your service provider.
  2. Manual Call Blocking: Consider blocking specific numbers manually using your phone’s call-blocking feature or a third-party app. Add unwanted numbers to your block list to prevent them from reaching you.
  3. Reporting to Authorities: If unwanted calls persist and become harassing or threatening, report them to the Federal Trade Commission (FTC) and the National Do Not Call Registry. Provide them with the necessary details and any documented evidence you have.
