How to Stop Spam Text Messages: Effective Security Tactics

Spam text messages, often known as SMS phishing or "smishing," are a common nuisance that can lead to privacy concerns, data theft, and even financial loss. Whether it’s a promotional text you never signed up for or a phishing scam trying to steal your personal information, it's important to stay protected. Below are effective tactics to stop spam text messages and keep your devices secure.

 1. Block and Report Spam Numbers

Most mobile devices come with built-in features for blocking specific numbers. This is one of the quickest and easiest ways to prevent repeat offenders from contacting you. 

 How to Block and Report Spam Texts:

- iPhone: 

   - Open the message, tap the contact at the top, and select "Info."

   - Choose "Block this Caller" and follow the prompts.

   - Additionally, you can report the message by forwarding it to 7726 (SPAM).

- Android:

   - Open the message and tap the three dots at the top.

   - Select "Block" or "Report Spam."

Most carriers also allow users to forward spam texts to 7726, which alerts them to potential fraud.

 2. Enable Spam Filters on Your Device

Both Android and iOS provide built-in filters that can automatically detect and sort spam messages.

- iPhone: 

   - Go to Settings > Messages and turn on Filter Unknown Senders. This will prevent any unknown numbers from reaching your main inbox.

- Android: 

   - Open the Messages app, tap the three dots, and go to Settings > Spam Protection. Enable the option to block suspected spam texts.

 3. Use Third-Party Spam Blocking Apps

Third-party apps offer advanced spam filtering features and work across most carriers and devices. Apps like RoboKiller, Truecaller, and Hiya help block spam texts and calls by crowdsourcing reports from other users. These apps frequently update their databases of known spam numbers and phishing attempts, offering an extra layer of protection.

 4. Don't Engage with the Message

Responding to a spam text or clicking on links within a suspicious message can confirm to the sender that your number is active. This often leads to an increase in spam. 

Key guidelines:

- Never click on links in spam texts.

- Don’t reply, even if the message prompts you to reply with a keyword like “STOP” to unsubscribe. Doing so could verify your number for further spam.

 5. Be Cautious with Personal Information

Cybercriminals often use spam texts to steal personal information through phishing attempts. These texts might claim to be from your bank, a government agency, or a well-known company, asking you to provide sensitive details.

- Legitimate companies will never ask for personal details via text.

- If you're unsure, contact the company directly using verified contact information.

 6. Opt Out of Unwanted Marketing Messages

Sometimes, spam texts come from legitimate businesses. If you no longer wish to receive these texts, most reputable companies offer an easy opt-out process by replying with “STOP.” Just be sure that the message is truly from a trusted source before responding.

You can also use the Do Not Call Registry to limit telemarketing messages and calls.

 7. Contact Your Carrier

Mobile carriers offer their own solutions for blocking spam. Some even provide services that scan your incoming messages and calls for suspicious activity. These services may be free or come with a small fee.

- AT&T Call Protect

- Verizon Call Filter

- T-Mobile Scam Shield

Carriers may also have settings to report spam or phishing texts directly from your phone, giving them more data to track down offenders.

 8. Avoid Sharing Your Phone Number Publicly

One of the most effective ways to prevent spam is to limit the exposure of your phone number. Avoid sharing your number on public forums, social media, or when signing up for questionable websites and services. Consider using a secondary number for non-essential accounts to reduce spam risk.

 9. Update Your Operating System

Security updates often include patches that protect your device from the latest phishing attempts and malware. Ensure that your device’s operating system is up to date to guard against known vulnerabilities that could be exploited through spam texts.

 10. Use Two-Factor Authentication (2FA) Cautiously

While two-factor authentication (2FA) is an excellent security feature, many people use text messages as their second factor. However, this can be risky if your number is compromised through phishing. 

Consider switching to a more secure form of 2FA, such as an authentication app like Google Authenticator, to reduce your reliance on SMS.

 Final Thoughts

Dealing with spam texts can be frustrating, but these security tactics provide multiple layers of protection. By blocking numbers, using spam filters, and being cautious with personal information, you can significantly reduce your exposure to these unwanted messages. Stay vigilant and make use of the resources provided by your mobile carrier and third-party apps for optimal protection.
