Protect Your Mobile Phone from Scam Calls: Top Apps and Solutions

Scam calls, often labeled as "Scam Likely," are a pervasive issue for mobile phone users in the United States. These fraudulent calls can lead to financial loss and personal information breaches. Fortunately, several applications and carrier-specific features are designed to help users identify and block these unwanted calls.

What Are Scam Likely Calls?

"Scam Likely" calls are incoming calls flagged by your carrier or device as potential scams. This designation is based on patterns such as high-volume calling, known scam numbers, or suspicious caller behavior. While these calls are not always malicious, it's prudent to exercise caution.

How Can I Block Scam Calls on My Mobile Phone?

1. Carrier-Specific Solutions:

  • T-Mobile Scam Shield: T-Mobile offers Scam Shield, which includes Scam ID and Scam Block. Scam ID identifies suspected scam calls and displays "Scam Likely," while Scam Block automatically prevents these calls from reaching your phone. To activate Scam Block, dial #662# and press call. Scam Shield Premium provides additional features for $4 per month per line. (perusemagazine.com)

  • Verizon Call Filter: Verizon provides Call Filter Free, which identifies spam and lets you report numbers. Call Filter Plus costs $3.99/month per line and adds personal block lists, spam lookup for unknown numbers, and enhanced caller details. (perusemagazine.com)

2. Third-Party Applications:

  • RoboKiller: RoboKiller uses AI-powered audio fingerprinting technology to identify and block spam calls, even when scammers change their numbers. It boasts a high success rate in blocking unwanted calls. (fone.tips)

  • Truecaller: Truecaller has a large database of known spammers and telemarketers that it uses to identify and block unwanted calls. It also provides reverse phone lookup services. (callwave.com)

  • Hiya: Hiya offers strong call blocking and spam protection powered by its AI system. It identifies spam calls and provides reverse phone lookup to identify unknown callers. (callwave.com)

3. Built-in Device Features:

  • iPhone: You can silence unknown callers by going to Settings > Phone > Silence Unknown Callers and toggling it on. This feature silences calls from numbers not in your contacts list. (aura.com)

  • Android: Many Android devices have built-in spam protection features. For example, Google is developing a system-level feature for Android aimed at combating spoofed calls, which will be integrated directly into Android via Google Play Services. (androidcentral.com)

How Do These Apps Compare to Carrier Solutions?

While carrier-specific solutions like T-Mobile's Scam Shield and Verizon's Call Filter offer basic protection, third-party apps like RoboKiller, Truecaller, and Hiya provide more comprehensive features, including AI-powered detection, larger spam databases, and additional functionalities like reverse phone lookup. RoboKiller, for instance, has a high success rate in blocking unwanted calls, making it a strong contender in the market. (fone.tips)

Are There Any Free Options Available?

Yes, some apps offer free versions with basic features. For example, Truecaller provides a free version that includes basic caller ID and spam blocking features. However, for more advanced features, a premium subscription may be required. (fone.tips)

How Can I Report Scam Calls?

In the United States, you can report scam calls to the Federal Communications Commission (FCC) through their website. Additionally, many third-party apps allow users to report suspicious numbers, contributing to the community-driven effort to block scam calls.

Conclusion

Protecting your mobile phone from scam calls requires a combination of carrier-specific solutions, third-party applications, and built-in device features. By utilizing these tools, you can significantly reduce the number of unwanted calls and safeguard your personal information.
