How to Stop Suspicious Messages on Your US Phone Number

Receiving suspicious messages on your US phone number can be both annoying and potentially harmful. These messages often come in the form of spam texts or scam calls, commonly known as "smishing." Implementing the right strategies can significantly reduce these unwanted communications.

What Are Suspicious Messages and How Do They Affect You?

Suspicious messages are unsolicited communications that may contain malicious links or requests for personal information. Engaging with these messages can lead to identity theft, financial loss, or malware infections. In 2024, consumers reported nearly 247,000 text-message fraud cases to the Federal Trade Commission (FTC), resulting in approximately $470 million in losses. (arxiv.org)

How Can You Identify Suspicious Messages?

Recognizing suspicious messages is the first step in protecting yourself. Look out for:

  • Unfamiliar Senders: Messages from unknown numbers or email addresses.
  • Urgent Language: Phrases like "Immediate action required" or "Your account has been compromised."
  • Suspicious Links: URLs that seem unrelated to the sender's claimed identity.
  • Requests for Personal Information: Asking for sensitive data like Social Security numbers or bank details.

What Steps Can You Take to Block Suspicious Messages?

1. Utilize Built-in Phone Features

  • iPhone Users:

  • Go to Settings > Messages.

  • Enable Filter Unknown Senders to separate messages from unknown contacts.

  • To block a contact, open the message, tap the contact's name, scroll down, and select Block this Caller. (usa.kaspersky.com)

  • Android Users:

  • Open the Messages app.

  • Tap the three-dot menu > Settings > Spam protection.

  • Enable Enable spam protection.

  • To block a number, open the conversation, tap the three-dot menu, and select Block. (uscellular.com)

2. Report Suspicious Messages to Your Carrier

Forwarding suspicious messages to your carrier helps them identify and block spam. Most carriers use 7726 (SPAM) for this purpose. For example, AT&T users can report unwanted calls and texts by forwarding the message to 7726. (att.com)

3. Use Third-Party Apps

Apps like RoboKiller, Hiya, and Truecaller maintain databases of known spam numbers and can automatically block or alert you to potential threats. These apps are available for both iOS and Android devices. (kiplinger.com)

What Should You Do if You've Already Engaged with a Suspicious Message?

If you've clicked on a link or provided personal information in response to a suspicious message:

  • Monitor Your Accounts: Keep an eye on bank statements and credit reports for unauthorized activity.
  • Change Passwords: Update passwords for accounts that may have been compromised.
  • Report the Incident: Inform your bank or relevant institutions about potential fraud.

How Can You Report Suspicious Messages to Authorities?

Reporting suspicious messages helps authorities track and combat scams:

  • Federal Trade Commission (FTC): File a complaint at ReportFraud.ftc.gov.
  • Federal Communications Commission (FCC): Submit a complaint through their Consumer Complaint Center.
  • Your Carrier: Forward the suspicious message to 7726 (SPAM). (legalclarity.org)

How Can You Prevent Future Suspicious Messages?

  • Be Cautious with Personal Information: Avoid sharing sensitive data over text messages.
  • Educate Yourself: Stay informed about common scam tactics and how to recognize them.
  • Regularly Update Your Phone: Ensure your device's software is up to date to benefit from the latest security features.

By implementing these strategies, you can significantly reduce the number of suspicious messages you receive and protect your personal information.
