How to stop spam texts on iPhone and Android phones

While it’s nearly impossible to avoid text message spam entirely, you can help cut down on it by reporting spam texts to your carrier and Apple. Thankfully, Apple has made this very easy to do in iOS 16 with a one-tap reporting feature. This can also be used to report the rare bit of text spam that comes through Apple’s iMessage service, but it’s best at helping you report SMS/MMS spam — as long as your carrier supports it. Here’s how to do this.

Step 1: Open the Messages app on your phone.

Step 2: Select a conversation that contains a spam text.

Step 3: Select the blue Report Junk link below the most recent message. As long as your carrier supports it, this should appear for any conversation for which the sender is not in your contact list, and to which you have not replied.

Step 4: Select Delete and Report Junk from the pop-up that appears at the bottom of your screen.

*Note that this does not automatically prevent future spam texts from this messager, but you can block the number manually. We’ll explain how to do that in the next section. *

You can block any number to prevent text messages from that number from getting through to your phone. Spam texts often come from a wide assortment of seemingly random numbers, so it probably isn’t worth your time to block every single one, but this can be handy if a large number of unwanted texts are coming in from the same number.

Step 1: Open the Messages app on your phone.

Step 2: Select a conversation that contains a spam text.

Step 3: Select the icon with the number at the top of the conversation.

Step 4: Select the Info button from the card that appears.

Step 5: Select Block this Caller at the bottom of the next screen.


Step 6: From the pop-up that appears, select Block Contact to confirm.

This will block both texts and phone calls from the selected number — including FaceTime audio and video calls. Incoming cellular calls will be sent to voicemail, FaceTime calls will be ignored, and texts will be silently discarded. Note that texts coming in from a blocked number cannot be recovered even if you later unblock the number.


You can view and manage your list of blocked contacts in the iPhone Settings app under Messages > Blocked Contacts.

You can automatically filter out messages from unknown senders — those not in your contacts list. Filtered messages will still appear in the Messages app, but they’ll be grouped into their own folder. You can also disable notifications for messages from unknown senders so they won’t disturb you or light up a badge on your Messages app icon. Here’s how to set this up:

Step 1: Open the Settings app on your iPhone.

Step 2: Scroll down and select Messages.

Step 3: Scroll down and find Filter Unknown Senders and select the switch to toggle it on.

Step 4: To also disable notifications for messages from unknown senders, scroll back up and select Notifications near the top of the Messages settings.

Step 5: Select Customize Notifications at the bottom.

Step 6: Toggle Unknown Senders off. Note that this setting only applies to notifications on your iPhone; you’ll need to turn it on separately on your iPad or Mac if you’re syncing your text messages to those devices.

Step 7: Once you’ve enabled the option to Filter Unknown Senders, a new Filters option will appear in the top-left corner of the conversation view in the Messages app. Selecting this will allow you to choose between viewing all messages or filtering the list by either known or unknown senders. There are also options here to filter by unread messages and view recently deleted conversations.

Step 8: Note that Apple considers any active conversation you’ve replied to as coming from a known sender, even if the number isn’t listed in your contacts. If you’ve replied to a spam text and want to revert that number to being treated as an unknown sender, you’ll need to permanently delete the conversation: 


1. In the Messages app, swipe to the left on the conversation you would like to delete and continue swiping until you feel some haptic feedback and see the red banner expand all the way across the screen.
2. Select Delete from the pop-up that appears.
3. Select Filters from the top-left corner.
4. Select Recently Deleted.
5. Choose the conversation you just deleted. A blue checkmark should appear on the left side to indicate it’s selected.
6. Select Delete from the bottom-left corner.
7. Choose Delete Message to confirm.

Blocking spam texts on Android can be trickier since just about every handset maker has its own take on the operating system, which often includes its own app for handling text messages. Thankfully, the most popular smartphone makers have more recently standardized on Google Messages. Here’s how to block spam there:

Step 1: Open the Messages by Google app on your phone.

Step 2: Select your profile picture or initials in the top-right corner.

Step 3: Select Messages settings.

Step 4: Scroll down and select Spam protection.

Step 5: Select the toggle beside Enable spam protection to turn it on.

Messages that are identified as spam will go into a Spam & blocked folder that can be accessed from the three-line hamburger menu in the top-left corner of the Messages app (the one with three lines on top of each other).

Unfortunately, enabling spam protection for the first time won’t scan your existing messages, meaning any messages you’ve already received will remain exactly where they are. However, you can manually report these as spam. Further, since Google’s algorithms aren’t perfect, some spam messages will slip through. Manual reporting will move these to the spam filter and help train your phone to better recognize similar patterns in the future. Here’s how to do this.

Step 1: Open a spam message in the Messages app on your phone.

Step 2: Select Report spam.

Step 3: Select the box beside Block to block the number permanently as well.

Step 4: Choose the Report spam button.

Step 5: Select the back arrow in the top-left corner to return to your message list. The reported conversation will no longer appear on the main list since it’s been moved to the “Spam & blocked” folder.

Step 6: You can also report a message as spam without opening it by long-selecting it in the Messages app and choosing the Block option from the three-dot menu in the top-right corner. This shows a pop-up box with the opposite behavior of the Report spam option; it blocks the message by default, with a separate checkbox to optionally report it as spam.

Apple and Google both provide “hooks” in their messaging platforms that allow third-party apps to scan your incoming text messages to try to determine if they’re spam before passing them on to your phone. As a result, a number of developers have taken up the challenge of trying to build better anti-spam filtering than what Apple and Google’s messaging apps offer on their own.

Traditional spam texts are usually pretty easy to spot, as they’re typically trying to sell you something. These are also fairly easy to ignore, but of course, the reporting and blocking options we explained above will help you filter out some of the noise.
