With spam texts on the rise, especially on iPhones and iMessage, we thought it would be helpful to put together a guide on how to block those annoying texts. I’m not sure about you, but I started using SMS messaging in 1999, and I only started receiving spam texts around a year ago. Go figure.
What makes this issue particularly irritating is that spammers have become more clever and sophisticated over time. Now, they not only spoof your area code but the prefix as-well, so it seems as if it’s actually a local phone numberp
This is done to trick users into thinking that the text itself is legitimate. And taking things even further, scammers are now texting unsuspecting users from their own numbers.
This issue, we should note, only impacts Verizon users, and the company claims that they’ve “made a significant effort to limit the current activity” of the scheme. But even if you’re not a Verizon subscriber, you could still probably stand to receive fewer spam texts. Here’s how to block spam text messages.
How iPhone users can stop spam texts
Filter unknown senders
One option to limit iPhone spam texts is to filter messages from unknown senders. With this option, spam messages originating from a number not part of your contact list will go to a separate folder.
To turn this toggle on, follow the below instructions. Before doing so, we should highlight that this filter might also catch non-spam texts from companies like Uber and Door Dash. In other words, if you turn this filter on, make sure to check the “Unknown Senders” tab in the Messages app often.
- Open the Settings app, and head to “Messages.”
- Turn on the “Filter Unkown Senders” toggle.
Unfortunately, the same technology that allows individuals worldwide to communicate is being leveraged by scam artists looking to take advantage of unsuspecting users.
To this point, scammers sent upwards of 11.6 billion spam messages during March. The New York Times notes that this represents a 30% increase from the previous month.
Block specific senders
While there’s no bulletproof way to block spam messages, iPhone users can take steps to limit their frequency and visibility.
One thing you can do upon receiving a spam text is to block the number. This will prevent spam messages from that number in the future. Follow the below instructions to do so.
- Tap on the spam message from the sender you want to block.
- Next, tap on the phone number at the top of the message.
- Tap “Info.”
- At the bottom of the list of options, tap “Block this caller.” Then tap “Block Contact.”
The number should now be blocked and unable to send you spam messages.
Report spam texts or junk messages in Messages app
When you use iMessage, Apple’s messaging platform, you can report spam messages. If the sender is not in your contacts and has other spam criteria, Apple sometimes offers a flag that says these messages might be Junk or spam. You can just tap that, tap the Report Junk button, and tap Delete and Report Junk.
When you do this, the person sending you the message is reported to Apple, and the message is then permanently deleted from your phone.
Get rid of calls and spam texts from unknown numbers
On a somewhat related note, there’s also a way to silence incoming calls from numbers not in your address book. The calls will still go through but will go straight to voicemail instead. Incidentally, phone calls from numbers you’ve previously texted with will be able to go through.
Go to Settings > Phone and toggle the Silence Unknown Callers option to turn this feature on.

Report the spammer to your carrier
This isn’t going to halt all incoming spam texts and calls immediately, but it benefits others, and if everyone reported these messages, there would be fewer spammers. Here’s how you can do it.
Take the original spam text and forward it, so it’s reported to your carrier. If you’re on AT&T, Verizon, T-Mobile, or Sprint, use this number: 7726 (SPAM).
File a complaint with the FTC
Under U.S. law, sending unsolicited text messages of a commercial nature without your consent is illegal. The Federal Trade Commission (FTC) oversees a complaint assistant you can use here to report spammers and scam texts and calls.
What are Robotexts?
A robotext is similar to a spam text message, but it’s an automated text message rather than a robocall. Sometimes robotexts are part of a larger play by spammers and scammers, hoping to reel you in so you provide some personal information that can later be used in a spam onslaught.
Some of these texts can lead to higher cell phone bills, identity theft, and even malware installed on your phone.
What’s the reason I’m suddenly getting spam texts and calls?
Spammers use any trick in the book to reach as many phone numbers as possible. They purchase lists of numbers available on the dark web and use software to automatically create and generate lists of numbers. Changing your number won’t prevent spam texts and calls because of this.
Should I reply to spam messages and robotexts?
The answer is no unless you signed up for a specific service that you’re trying to cancel. Usually, if you reply with “STOP,” it can unsubscribe you from the messaging list with reputable businesses and vendors.
Suppose you reply “STOP” to a scam text. In that case, it can actually notify the sender that this is a valid number and a person is replying, giving them more of an opportunity to try and scam or phish your information. Additionally, since the number is valid, it can be added to more spam lists and increase your spam texts and calls.
