Effective Strategies to Block Spam Calls on Your Smartphone

In an era where our smartphones are central to our daily communications, the inundation of spam calls can disrupt our day-to-day lives. This article provides a refreshed and comprehensive guide to help you understand and eliminate unwanted calls, ensuring your phone is a source of convenience, not frustration.

Understanding and Combatting Spam Calls

Spam calls can range from mere nuisances to serious security threats. Unwanted marketing calls, fraudulent schemes that impersonate banks or authorities, or robocalls that waste your time, are all too common. Thankfully, there are several avenues to safeguard yourself from these interruptions and enhance your peace of mind.

Begin with Basic Blocking Techniques

Starting with simple steps, you can block specific numbers on both iPhone and Android devices. Though this isn’t a solution for all spam calls, particularly those from numbers that frequently change, it is effective for persistent unwanted callers. On iOS, navigate to the Phone app, tap on Recents, then the blue information icon next to the number you wish to block, and select “Block this caller.” Android users can access their Recent calls via the Phone app, press and hold the number, then choose “Block.”

Carrier-Level Protection Services

The major mobile carriers offer built-in services to identify, block, and even report spam calls, leveraging SHAKEN/STIR technology to verify calls. Carriers provide free baseline services as well as premium features for added protection. For instance:

  • AT&T’s Call Protect service helps detect and prevent suspicious calls.
  • T-Mobile offers Scam Shield, complete with Scam ID, Scam Block, and free Caller ID.
  • Verizon’s Call Filter alerts you to potential spam and allows for number blocking.

Each carrier grants customers the ability to create personalized block lists and offers optional services at an additional cost for more comprehensive protection.

Third-Party Apps: An Additional Layer of Defense

Applications such as Nomorobo, RoboKiller, and Hiya specialize in thwarting robocalls by referencing a constantly updated list of spam numbers. Subscribers to these services have the flexibility to manage their own blacklists and ensure important calls are not mistakenly blocked. While these apps require an active subscription, they offer robust features compatible with the latest mobile operating systems.

Leveraging Built-In Smartphone Features

Google Pixel and Samsung devices, among others, include features to mark or block suspected spam callers. Moreover, with iOS 13 and later, Apple introduced the Silence Unknown Callers function, which can filter out calls from numbers not found in your contacts or recent communication history.


Equipping yourself with the knowledge and tools to stop spam calls empowers you to reclaim control over your phone. Staying vigilant and proactive in protecting your personal space from unwanted calls is not only beneficial for your privacy and well-being but it also enhances your smartphone experience.


Q: What is the most reliable way to prevent spam calls on my phone?

A: Utilize carrier-level protection services, enable built-in phone features, and consider subscribing to reputable third-party apps for comprehensive spam call prevention.

Q: Is it worth investing in premium spam-blocking services?

A: If you are experiencing a high volume of spam calls, premium services can offer advanced blocking options and personalized control that may justify the cost.

Remember, keeping your smartphone’s software up-to-date and staying informed about the latest spam trends are crucial in fortifying your defenses against invasive calls. Combat spam with confidence using these expert strategies.
