Act at the source: remove your data from data brokers

Call-blocking services and tools will reduce the number of spam texts you receive, but only short term. If you keep receiving random text messages, then your phone number is probably available on the internet. The best and more effective way to handle spam messages is to manage your online footprint and restrict access to your personal and financial information. Read on to learn how.

Before sending you a spam text, the spammer has to know your phone number. There are several options:

  • You may have shared it publicly via social media.
  • You may have given it to a legitimate company that then suffered a data breach. 
  • You may have entered it on a scammy website that gives or sells data to spammers. 
  • Your data may be for sale on data broker sites. 

To remove your data, you can contact each data broker individually and use your knowledge of any local laws they operate under to request that they delete your data from their databases. Or, you can use a service like Incogni to remove your data from data brokers and people search sites with just a few clicks.

Add your number to the FTC Do Not Call Registry

Start by adding your number to the FTC’s Do Not Call Registry (DNC) to prevent telemarketers and other unwanted callers from contacting you. The DNC registry has been successfully preventing unwanted calls in the US since 2011, and the number of Americans who’ve registered their numbers is steadily growing. We strongly encourage you to join the club. 

Here’s how:

  1. Go to
  2. Click on “register your phone number.”
  3. Enter the phone number you want to register.
  4. Verify your phone number.
  5. Click “submit.”

Most phone carriers have an app that alerts you about incoming spam calls. But don’t fret! Some providers have apps designed to help you deal with spam messages as well:

  • Verizon offers the Call Filter app. It provides spam detection, text blocking, filtering, a white-list option for iOS, and a neighborhood spoofing filter.
  • US Cellular has the Call Guardian app offering caller ID, spam alerts, and spam reporting. Also, it lets you create a personal spam block list.
  • Google Fi has blocking options in the app itself.

Get a spam-blocking app 

On Android

If you don’t want to use the Google messages app and if your cell service provider doesn’t offer any solutions, there’s still a way to stop spam texts on Android. Your best bet might be to get a spam-message blocking app. Such apps filter unknown senders and warn you of suspicious messages.

There are plenty of apps to choose from, so you can find one that works for you and stick with it. Nomorobo and RoboKiller are two of the most popular ones, but take your time to explore the market and find your perfect fit. 

On iPhone

Some third-party apps for iPhone automatically block and filter unknown messages and spam for you. To name just a few: RoboKiller, TextKiller, Hiya: Spam Blocker & Caller ID, and Nomorobo Robocall Blocking.

Once you’ve downloaded it, the app should be up and filtering by default. If it’s not, here’s how to enable (or disable) it manually through iPhone settings:

  1. Go to “settings.”
  2. Tap “messages.”
  3. Tap “unknown” and “spam” under message filtering.
  4. Pick the filtering app you downloaded and toggle it on.

Block and report spam texts on Android devices

There are several things you can do to significantly reduce the number of such texts you receive on your Android device:

  1. Block spam text from a specific sender’s phone numbers
  2. How to enable spam protection on your Android phone

Block spam text from a specific sender’s phone numbers

Your Android device allows you to block phone numbers. So as soon as you receive a spam text, you can block the sender’s number and never hear from them again. This is particularly useful if you keep getting spam messages from the same number.

2. Tap the three-dot menu in the top-right corner.

3. Tap “block & report spam.”

  3. Tap the three-dot menu in the top-right corner.
  4. Tap “block.”
  5. Confirm by tapping “OK.”
  6. Optionally, mark “report spam” to also report the spam to Google. This may incur charges for sending the message.

How to enable spam protection on your Android phone

This is only an option if you’re using the Messages by Google app, but worth mentioning nonetheless. It’s the primary messaging app on many Android devices; you can download it if your phone doesn’t already have it and you don’t mind the privacy risk.

Here’s what you need to do to filter messages on this app:

1. Open the app and tap the three dots in the top-right corner of the screen.


2. Tap on the “settings” option.


3. Select “spam protection.”

4. Open the “spam protection” settings and toggle on the “spam protection” feature.


How to recognize malicious spam texts

Some legitimate texts include links. And some spam text sent by legitimate companies can be stopped by replying with something like the word “STOP.”

The key difference is that marketing spam is simply annoying, while malicious spam can be very dangerous. So, it’s crucial that you be able to tell an advertisement from a malicious spam text message. Here’s how:

  • Sense of urgency: scammers try to make you feel like you have to react to their message without taking the time to think about it. If you feel pressured to take action, it’s quite likely to be a text sent by bad actors.
  • Texts from authorities: hackers often pretend to be someone with authority. The IRS won’t be sending you an SMS, nor will any other government agency. Don’t open any links or otherwise interact with messages that look like they’ve been sent from a governmental authority.
  • Bad grammar and spelling: a surprising number of hackers can’t put a sentence together. Scam messages are often poorly written and contain grammar and spelling mistakes. This is a dead giveaway of a message you can’t trust.
  • Verify suspicious activity: you may get a text message asking you to verify an account login or a transaction with a link attached to it. Once again, such messages are rarely sent by text message. Don’t click any links unless you’re 100% sure they’re legit.
  • Failed delivery attempt: another very common scam message. There was a failed attempt to deliver a package to you, click on the link to reschedule delivery. Only issue: the link is malicious and installs malware on your device.
  • Help! You may receive a spam text message from someone pretending to be a family member asking for help. Call them and make sure everything is OK, which will usually be the case. Once again, don’t click any links or otherwise interact with such texts.

Keep in mind that phone numbers are notoriously easy to spoof. Just because you think you’re getting a text message from a trusted contact, doesn’t mean that you are. Any suspicious text should be treated with caution, even if it comes from one of your closest loved ones.

Don’t answer or interact

This is more of a preventive measure to take once you receive a spam text. Don’t reply or interact with the text message in any way. By replying to a message, you show that your phone number is active, which means it will get more messages from spammers in the future.

If there is a link attached to the message, it’s very likely to contain malware. Pressing on the link may end up being a very costly mistake. Hackers can steal your sensitive information or even take complete control of your phone.
