If you use iPhone, iOS includes built-in junk message blocking features you can activate in just a few taps:

  1. Enable Filter Unknown Senders
    Go to Settings > Apps > Messages > Filter Unknown Senders and turn it on. This automatically moves texts from people not in your contacts into a separate tab.
  2. Block and Report in Messages
    Open the spam text > tap the sender > Info > Block this Caller. If you see the Report Junk option in Messages, tap it to notify Apple directly.
  3. Report to Carrier via 7726
    Forward the spam text to 7726 (SPAM). This is free for most carriers and helps them better identify scam sources.
  4. Use Third-Party Apps
    If you’re looking to be even more vigilant in your fight against spam texts, you can try well-reviewed third-party spam blocking apps like Nomorobo, RoboKiller, Truecaller or Hiya.

    For even more spam text prevention, trusted third-party apps like Truecaller, Hiya, Nomorobo and RoboKiller offer large spam databases for increased protection.


How to Tell if a Call or Text is a Scam

Scammers often rely on urgency and confusion. Knowing what to look for can help you avoid falling victim:

  • Unexpected messages asking for personal information
  • Urgent requests like “Act now or your account will be closed”
  • Requests for payment via gift cards, wire transfers, or unusual methods
  • Links in texts from unknown senders

If something doesn’t feel right, trust your instincts. Legitimate organizations won’t pressure you or ask for sensitive information unexpectedly.


Tips to Prevent Spam Calls and Texts

While you can’t stop every spam attempt, these steps can significantly reduce them:

  • Don’t answer unknown numbers—let them go to voicemail
  • Avoid sharing your phone number publicly online
  • Never click on suspicious links in texts or emails
  • Don’t reply to spam messages, even to say “stop”
  • Register your number on the National Do Not Call Registry

Taking these precautions helps limit your exposure and keeps your number off scammers’ lists.


How to Handle Spam Texts

Spam texts are becoming more common—and more convincing. Here’s how to stay safe:

  • Delete suspicious messages immediately
  • Block the sender through your messaging app
  • Never tap links from unknown sources
  • Do not provide personal or financial information via text

Remember: even if a message looks like it’s from a bank, delivery service, or government agency, always verify through official channels before taking action.


Reporting Spam and Fraud

Reporting spam helps protect not just you—but others as well. You can report suspicious calls and messages to the Federal Communications Commission (FCC) at reportfraud.ftc.gov or through your phone carrier.

Many smartphones also allow you to report numbers directly when blocking them, which helps improve spam detection systems.


Stay In Control – Spam calls and texts can feel overwhelming, but you’re not powerless. By using your phone’s built-in tools, staying cautious with unfamiliar messages, and taking a few preventative steps, you can dramatically reduce unwanted contact.
