How to stop spam texts: 8 do’s and don’ts

They’re about as welcome as robot calls and junk mail — spam text messages.

They show up as unwanted and unexpected text messages on our phone screens. That’s aggravating enough, but it gets worse. Whoever is sending you a spam text message is likely trying to defraud you.

Most spam text messages aren’t coming from another phone. They’re often originating from a computer and being delivered to your phone — at no cost to the sender — via an email address or an instant messaging account.

Besides being painfully annoying, spam texts pose the risk of exposing you to identity theft, installing malware on your device, and accessing your personal information. It’s illegal to send unsolicited commercial text messages to a wireless device unless the sender gets your permission, according to the Australian Communications and Media Authority.

Don’t despair. You can reduce unwanted text messages and help prevent them from showing up on your phone and other mobile devices. Read through this guide to learn the do’s and don’ts of dealing with spam texts and how to stop spam texts for good.

1. Don’t reply directly to any spam text message

Directly replying to a spam text message lets a spammer know that your number is genuine. What happens next? They can sell your phone number to other spammers who might bombard you with promises of free gifts and product offers.

2. Treat your personal information like it is cash

Spam text messages may lure you into disclosing personal information like how much money you make, how much you owe the bank, your Medicare number and credit card details. Most legitimate companies do not request personal information like passwords, account details, and other personal details via text message.

When in doubt, look up the company phone number, call them and verify if a legitimate request was made. Don’t call the number sent in the text message.

3. Don’t click on any links in the text message

Clicking on a link in a spam text message could install malware that can collect information from your phone. It can take you to spoof sites that look real but are designed to steal your information. Malware can also slow down your cell phone’s performance by taking up space on your phone’s memory. Once the spammer has your information, it can be sold to marketers or, worse, identity thieves.

It can also lead to unwanted charges on your mobile phone bill. Your mobile provider may charge you for receiving a text message, regardless of whether you requested it.

4. Do review your mobile phone bill regularly

It’s smart to check your phone bill regularly to make sure it reflects the correct amount. If there are charges that don’t look right, call the phone company and find out if you’re receiving or sending spam messages from your phone.

5. Do check your phone’s settings

Your phone probably has built-in features to help block unwanted calls and text messages. Type in “block” using your device’s search function.

For Android phones, look for the three dots in the top right-hand corner of your text. Click on it and select “People” and “Options.” Next, select “Block” to stop receiving spam text messages from that number.

For iPhones, click on the “i” in the top right-hand corner of the spam text. Next, click on the number and select “Block.”

6. Do place your mobile phone number on the Do Not Call Registry

Wondering how to stop spam calls? Adding your phone number to ACMA's Do Not Call Registry lets you opt you out of receiving most telemarketing calls. If you receive an unwanted call after your number is on the registry for 31 days, you can report it to the ACMA.

7. Do check to see if your mobile phone provider offers a call-blocking service

Most major mobile service providers offer call-blocking services or plans that let you block phone numbers from unknown callers for a specific period of time. You can also see if one of the third-party call-blocking apps and services will work with your provider’s wireless service.

Wondering how to block text messages? These call-blocking services or apps can usually block texts as well. 

Some third-party call blocking apps* include:

  • Hiya
  • Robokiller
  • Truecaller

8. Do report spam texts to your mobile phone provider
