How to Stop Unwanted Text Messages on iPhone

Comment arrêter les SMS non désirés sur l'iPhone

Your iPhone now only vibrates and emits sound notifications. For what ? Phone numbers belonging to people who are completely unknown to you quickly send you countless messages filled with advertising and other unwanted content. Everything is getting frustrating and right now it's almost impossible for you to concentrate on what you have to do. Your phone buzzes continuously like a call center.

So you have taken charge of the situation. You sat down at your computer and started scouring the internet for a solution to the problem. You asked Google “how to stop unwanted text messages on iPhone”, and here you are. So, while you're at it, let me help you out by telling you how to block spam messages on your iPhone.

Why are you receiving unwanted text messages on your iPhone?

You receive unwanted text messages on your phone because the sender is trying to extract information from you to scam you. As we mentioned in another article answering the same question, unwanted SMS or spam messages contain malware that can steal your private information when installed (by clicking on sent links, etc.).

You may also receive unwanted text messages because some companies you signed up with have shared your number with telemarketers. Therefore, they have your number in their target list for their products or services. These telemarketers are hard sellers who market their products by force using any unethical means. As I explained above, you can file a complaint or complaints and pursue them using a bot revenge service.

Next, I will show you how to stop unwanted text messages on iPhone from one contact or multiple contacts using three different methods:

    How to block a contact from the Settings app

    1: Launch the iPhone Settings app

    Launch the iPhone Settings app - Stop unwanted text messages on iPhone

    The Settings app has a gray gear icon in your device's home screen.

    This method is ideal when you need to block one of the existing contacts in your phone's address book and prevent them from sending you a text message. However, you cannot perform the same operation with a number, which is not in the directory. You can use this method to block receiving further text messages from an unknown number that has already contacted you.

    2: Tap Messages

    Scroll down and select the Messages option. It’s about halfway through the “Settings” menu.

    3. Tap “Blocked”.

    You will need to scroll down the Messages screen to be able to select the Blocked item. It's in the middle of the page, in the SMS/MMS section.

    4. Select “Add New”.

    Scroll through the new menu and touch the Add new… item. It is at the bottom of the list of blocked numbers.

    If the list of blocked numbers is empty, only the indicated option will be present, so you will not need to scroll down the page.

    5. Find the contact you need to block

    Scroll through your phone's address book until you find the person you want to block, then tap their name. This person will be added to the list of blocked contact names.


    Unfortunately, the iOS operating system does not allow you to block the reception of all SMS messages, except those sent by authorized numbers. Therefore, it is only possible to block numbers already in your phone's address book or those from which you have already received an SMS.

    Adding a phone number to the blocked list is impossible without having received a call or having it in the device's address book.


    Contact your mobile carrier if you continue to receive numerous text messages from unknown senders. Your service provider can directly stop the unwanted text messages you receive, since the support staff has much more powerful tools than can typically be found online.
