If Anti-SMS Spam and Text Filters on Your Phone Don’t Suffice, Use DoNotPay!

Spam is here to stay. The more we use our electronic gadgets and increase the time spent online, the easier spam finds a way to reach us. Ranging from robocalls to spam emails, spam takes different disguises. Spam text messages are gaining momentum lately, and they are particularly annoying.

Reaching for your phone to check the latest notification only to realize it’s an unsolicited text from an email address or a group text with a suspicious-looking link is disappointing enough. Spam text messages can also incur some serious financial damage.

Depending on your cell phone plan, you might be charged for all those unnecessary incoming messages. Even more dangerous is opening links from unknown senders since they can contain malware that spreads through your phone and steals all your sensitive information.

How To Recognize Spam Text Messages

Spam text senders are getting more and more creative, and precaution is advised when you get texts from unknown numbers. Some general characteristics that can help identify a potentially dangerous spam text are:

  • It comes from a company you trust but contains a lot of typos and links with not-quite-right URLs
  • The text’s content pushes you to act immediately upon some warning
  • It offers free prizes, discounts, and gifts for no reason
  • It uses generic, impersonal greetings

Your Phone Comes With Anti-SMS-Spam and Text Filters That Can Help

Realizing how dangerous spam text messages can be pushed phone manufacturers to spend more time on developing built-in solutions for fighting spam of all kinds, including unsolicited SMS. The available options differ based on which phone you use.

Anti-SMS Spam and Text Filters on iPhones

Apple started paying more attention to spam texts with iOS 11, improving the feature with every new iteration. If you haven’t turned on this feature by now, here’s how you can do it on the latest iOS versions:

  1. Open the Settings app
  2. Scroll down and tap on Messages
  3. Find Filter Unknown Messages (it’s way down on the list of settings)
  4. Tap on the toggle button to make it active

In the default messaging app, you will notice a new tab named Unknown Senders. Messages from unsaved contacts will immediately go there and won’t trigger a notification when received. Make sure to check this inbox from time to time so you don’t miss important texts from people whose numbers you haven’t saved.

If an occasional spam text pushes through, use the default iPhone options to block texts one by one.

Anti-SMS-Spam and Text Filters on Android Phones

The Android ecosystem is more diverse, and even though most features are available to all users, some options might not exist across all phone brands powered by this operating system. Check if your phone has a built-in text filter by following these steps:

  1. Go to the Messages app
  2. Tap on the three vertical dots in the upper right corner and select Settings
  3. Choose your SIM card
  4. Select Spam protection
  5. Tap on the toggle button next to Enable spam protection

In case you’re not satisfied with the filter’s efficiency, you can always stop spam texts on Android by blocking the sender.
