How to block text messages on iOS and Android
Regardless of which feature-rich smartphone you have, its main function is to keep you in contact with the people in your life. Calling someone is one way to catch up, but it’s hard to argue against texting and SMS messaging, which, for many, is faster and more convenient.
However, there are times when you may receive a message from a contact you’d rather not see again, or get a random message from someone with a questionable number. Sure, you can delete the message and move on, but a much more permanent solution is to block those people entirely, thereby preventing their texts from reaching you until you decide otherwise. Thankfully, both iOS and Android devices allow you to easily do this, and we’ve broken down how to block text messages on your cell phone.
If you’re looking for a guide on how to block numbers from calling you, we’ve created guides on blocking calls on Android, and blocking calls on iOS too.
Blocking texts in iOS
Block texts from known contacts and phone numbers
Blocking texts in iOS requires a little more than simply blocking the phone number or contact in question, even though that will stop you from receiving notifications from those people when they try to reach out. For messages specifically, tap the message from the contact you want to block, then tap Details in the top-right corner. Again, in the top-right corner, you’ll want to tap the “i” icon to open the Info page, then tap Block this Caller at the bottom of the page.
Another way is to go to Settings > Messages > Blocked and tap Add New to add a new blocked contact. Using either method, you’ll not only block messages, but also phone calls and FaceTime calls. This saves you from having to go to the Phone and FaceTime apps and settings to block the same person.
Block texts from numbers that appear as “unknown” or “private”
Unfortunately, you can’t outright block unknown and private numbers in the same way you can known contacts. You can, however, filter and separate them from the rest of the people you know. Go to Settings > Messages and toggle on the Filter Unknown Senders option. This will create a new tab in your Messages app called “Unknown Senders,” but you won’t get notifications for these. It may not be ideal, but it’s a decent compromise.
Report Spam iMessages
Another thing you can do is report spam and junk iMessages. When you get an iMessage from someone you don’t know, there will be a “Report Junk” link. Tap the link to forward the sender’s information and message to Apple. The company should deal with the contact and eventually render the person or bot unable to message you again.
You can also email Apple at “firstname.lastname@example.org”. Keep in mind that you’ll need a screenshot of the message, as well as the email address or phone number that sent the iMessage, and the date and time you received it.
Apple doesn’t deal with SMS and MMS messages, but you can always report them to your carrier. AT&T, for example, suggests sending the spam message to 7726 (SPAM). Afterward, the carrier will look into the message.
Blocking texts in Android
On a Google phone
There are two ways to go about blocking messages on a Google phone, like the Nexus 6P, 5X, or the Google Pixel. The first is to open the Messenger app, then open or start a conversation with one of your contacts. Tap More — represented by three vertical dots — select People & options, and tap Block. You can also open the Messenger app, touch and hold the conversation you want to block, tap Block when the option appears in the top-right corner, and tap OK.
On a Samsung phone
Like on a Google phone, Samsung phones have two ways to block messages. One method involves opening Messages, then choosing the conversation that contains the contact you want to block. From there, tap the More icon, select Block number, and toggle Message block to “On.” Then, tap OK.
Alternatively, head to Messages > More > Settings. Tap Block messages to select the check box, then tap Block list. From here, manually enter the contact’s number and tap the ‘+’ sign, or choose from your inbox or contacts list. When you’ve entered all the numbers you want to block, tap the back arrow.
On an LG phone
LG’s blocking process is fairly quick and straightforward. Start by opening LG’s messaging app and tapping the SMS or MMS message you want to block. Then, tap the three dots in the upper-right corner, then tap Block number to confirm your choice. The number should now be blocked.
On an HTC phone
Much like LG’s blocking process, HTC’s way of blocking unwanted messages is quick and easy. Open Messages, then tap and hold the desired text conversation until the Message options appears. Then, tap Block contact.
Using your carrier
Many mobile carriers provide services and additional settings to help their customers block messages from specific numbers, like those from telemarketers. T-Mobile has Message Blocking, Verizon has Block Calls & Messages, Sprint requires using Limits and Permissions via My Sprint, and AT&T has Smart Limits.
Block texts with Android apps
Additionally, there are dozens of apps in the Google Play Store that you can install to your Android device if your looking for more ways to block numbers and messages. Below are four we recommend checking out if you want to go down that path.
Clean Inbox – SMS Blocker (free)
SMS Blocker will block SMS messages and automatically remove spam on your behalf. Both sets of messages can be filtered out and blocked by using the phone number, a sender phrase, or a specific content word. Blocked messages are placed in their own separate folder, and can also be exported in a Notepad format, presumably to make it easier to save them for future reference. This is all included in the free version of the app, though the premium version lets you block all unknown numbers, add password protection, and provides an option to automatically delete SMS messages. You can also use it to remove the limit placed on the number of Block/Allow list entries.

Block call and block SMS (free)
While this isn’t specifically made to block SMS messages, it’ll do the job all the same. The app’s main focus is dealing with phone calls, which involves managing a blacklist, but the end result lets you use your phone without being interrupted by unknown callers, texts, and the notifications that accompany them. One potential downside to this app, however, is that it needs to be set as the default SMS app in order to effectively block SMS messages. That could be a major turn off if you’re already a fan of another messaging app.

Text Blocker (free)
Unlike the Block call and block SMS app, Text Blocker (aka Postman) doesn’t need to be your default SMS app in order to work. Instead, it works with just about any other messaging app. It will also begin blocking messages and spam as soon it’s installed, but that doesn’t mean you can’t customize it like the rest. In fact, you can change the spam filter level to tone down how much it blocks, and recover messages you accidentally blocked with a single tap. Text Blocker also has a useful feature known as Smart Notifications, which allows you to adjust how often you’re notified of new spam messages. Notifications can also come in instantly, be delayed, or turned off completely. Best of all, it’s compatible with Android 7.0 (Nougat), so you can run the Android N developer preview without one breaking the other.

Truecaller is the successor to the widely popular Truemessenger app, and it fulfils much the same niche, allowing users to instantly recognise when a spam number is calling or messaging, and will automatically block marketing emails. Their powerful Caller ID system will also name and shame unknown numbers that call you, making this one of the best apps for knowing who’s messaging you. Used by over 250 million people, this is a strong contender for being your blocking app.
