We all get unsolicited pings from spammers and unknown random numbers from time to time. Even if you have one of the best Android phones or the best iPhones in the market, it is inevitable that you will receive spam. While text messages aren’t as annoying as telemarketing calls, they can still get on your nerves by cluttering your inbox with their volume. Not to mention that many of these spam emails pose a security threat because they often contain a link that they want you to click on.

It is always best to delete these spam emails as soon as you receive them. But if you don’t want to bother dealing with them all the time, there are ways to filter out these spam messages and even stop them from reaching your phone. In this article, we’ll tell you how to block spam on your phone for both Android and iPhones.

How to Block Spam on Android

Blocking spam on Android phones is more difficult than on iPhones. We say this because of the large number of Android phones with custom skins on top of the vanilla Android experience. We will, however, try to simplify the process and present an easy and reliable workaround to effectively block spam on Android phones.

The first thing we recommend you do is download the Google Messages app on Android. This particular app comes pre-installed on Pixel devices, but you will need to download it manually from the Google Play Store on other devices like Samsung, Vivo, etc. The Google Messages app comes with a spam protection feature that works surprisingly well to keep spam messages at bay.


There are several ways to get rid of spam using the Google Messages app. So let’s see:

  • Once you have downloaded the latest version of Google Messages from the Play Store, open the app and tap the Account button, and search for an option name Message settings.
  • Now scroll down until you find the Spam Protection option.
  • Tap it and toggle Enable spam protection on.

This particular option will start reporting spam emails and even stop them from spamming you in the future. This works for the most part, but there are times when certain numbers can pass the Google Messages spam filter. Luckily, you can catch those numbers quite easily thanks to the spam filter that does the heavy lifting of keeping your inbox clutter-free. If a particular number is bypassing the built-in spam filter or if you’re receiving spam from a specific unknown number, here’s how to report spam on Android:

How to Report Spam Text on Android Phones

  • Simply locate the spam text in your inbox and long press on that particular message.
  • Once selected, tap the three dots icon to open the menu in the top right corner of the screen.
  • From there, press the To block option.

Google Messages will automatically move the message to the “Spam & Blocked” list, preventing it from texting or calling you in the future. Additionally, you can check the “Report spam” option to send that particular number to Google as well as your carrier.

If you don’t want to use Google Messages on, say, a Samsung phone, we suggest exploring your native messaging app and looking for an option to block spam. Almost all custom skins, including Samsung’s One UI, come with built-in spam protection features to prevent spam messages from reaching your inbox. Samsung’s Galaxy S22 running One UI 4.1 comes with a feature that lets you block numbers and spam in the Messages app. Here’s how you can access it:

  • Tap the three-dot menu in the upper right corner of the screen to open a list of menu items.
  • Now press Settings and look for an option named Block numbers and spam and activate Caller ID and spam protection. You can also use this option to block unwanted calls.

How to Block Spam on iPhone

It is relatively easier to restrict spam messages on iPhones. This is because “Messages” is the default messaging app on all iOS devices. It’s also useful that enabling a simple message filtering option on iPhones can prevent spam messages from reaching your main inbox. Here’s how to block spam on your iPhone with the message filtering option:

  • Open the Settings the app and go to posts.
  • In the Messages option, look for an option named Filter unknown senders and activate it.
  • Now go back to your Messages app to see a bunch of options that let you select which messages you want to see. Select Known senders to see only messages from your saved contacts or those you have already texted.

You can always return to this menu and choose to see messages from unknown senders as well. We suggest you keep an eye on this particular tab as it also includes messages from banks and other organizations that might send important messages like a transaction alert or verification code. So, if you are expecting an important notification from an unknown sender, keep an eye on this tab. You can also choose to view all messages at once, but this view will also include all spam messages.

Alternatively, you can also block individual numbers on iOS to completely stop receiving messages or phone calls from that particular number. Here’s how:

  • First, locate a conversation with the contact you want to block.
  • Now tap the contact at the top and then tap the information button, scroll down and press Block this caller. Once blocked, you will not receive notifications when they spam you with text messages.

Well, that pretty much concludes this tutorial on how to block spam messages on your Android phone or an iPhone. Before we share our final thoughts on this topic, however, there’s one last thing we wanted to point out: the use of third-party apps to block spam.


Third-party apps to block spam on your phone

There is no shortage of third-party apps on Android and iOS that allow you to block spam on your phone. Apps like Truecaller, RoboKiller and SMS Shield are some of the very popular names among users. Many of these third-party apps filter and block unwanted messages better, but they also ask for permission to access your call logs, messages, contacts, etc. This is one of the reasons why we didn’t recommend any third-party spam blocker apps in this tutorial. If you don’t mind, feel free to check out some third-party apps that will help you filter spam more effectively.


Final Thoughts

Android and iOS have improved a lot over the years and are now better at filtering and blocking spam. There’s always more room for improvement, but we expect to see more ways to filter and block spam messages in future versions of Android and iOS. We’ll try to revisit this article once we get our hands on the final builds of Android 13 and iOS 16, so stay tuned.
