Are you getting a lot of spam text messages? It can get tiring to be interrupted by a notification on your iPhone, only to find it's yet another junk message. Like phishing emails, these messages are often the starting point for scammers targeting potential victims. These scammers may pose as marketers selling a product or as ordinary people trying to connect with a friend but pretending to have the wrong number.
The good news is that you can stop these using a feature already available in iOS -- it's just a little hidden. Here's how you do it.

How to stop spam text messages on iPhone
What you'll need: To follow this tutorial, you'll need the latest version of iOS available for your device.
Open the Settings app on your iPhone, scroll down until you can access Apps, and tap on the Messages option.
Tap on Messages to access the settings for your Messages app.
Scroll down to find the Filter Unknown Messages option and turn it on. This option is turned off by default, so you'll need to toggle it to the "on" position to enable it.
Note: When enabling the Filter Unknown Messages feature, it's important that you add all known senders to your contact list. This will ensure you don't miss an important message from someone you haven't added to your address book, like a school using a messaging service.
Scroll to the end of the Messages settings to find "Filter Unknown Senders."
Go to the Messages app and check the Filters option. There will be a list of the following options:
All messagesKnown sendersUnknown sendersUnread messagesRecently deletedYou can stay in the Known Senders filter if you want to ignore spam or unknown messages. This filter will show you messages from numbers in your contact list and those with whom you've interacted.
Enabling the Filter Unknown Senders in your Settings will ensure you only receive notifications when someone messages you from the Known Senders list. You won't be notified if an unknown sender sends you a message, but you can always access these messages by going to the Unknown Senders list in your Messages app.

If you're expecting a message from someone you know, ensure their number is saved in your contacts or check the Unknown Senders tab often. Services like Instacart, DoorDash, and Uber Eats also use rotating custom text message numbers to communicate with customers, which won't be in your contact book. If you're expecting a delivery, I'd recommend checking the Unknown Senders tab during your delivery window.
The message inbox will now default to show messages from people in your contact list only.

Why am I getting so many spam text messages?
Remember those "extended car warranty" calls that got popular a couple of years ago? This annoyance made government agencies like the Federal Communications Commission (FCC) and cellphone companies crack down and take measures to stop them.
Some phone companies started flagging incoming calls as "Spam Caller" or "Scam Likely," making it easier for individual users to decline calls and block numbers. People blocking incoming calls from unknown numbers have made scammers switch to other avenues, which is one reason why spam text messages are at an all-time high.
