How to block unwanted messages on mobile: Android

Let’s start with how to block unwanted messages on an Android phone : I already warn you that the procedure below, in addition to SMS, will also prevent you from receiving calls from the numbers you choose to block. First, launch the Google Messages application , which should be the one you already use to read SMS.

Then, tap on the preview of the last message received from the number from which you no longer want to receive SMS and, once the conversation screen opens, press on the user’s number displayed at the top left.

On the next screen, tap the ⁝ icon located at the top right, select the Block numbers item and, if you deem it appropriate, check the Report as spam item (if the check is already shown, do not press anything) . Finally, proceed by pressing on the Block item and that’s it: you will no longer receive messages or calls from the selected number. It wasn’t difficult, was it?

In case of second thoughts, to unblock an aforementioned number, go to > Blocked conversations and spam> > Blocked Contacts and, in the screen that is shown to you, press the X icon next to the number you are interested in.

Want to know how to block unwanted advertisements on mobile ? You can apply this same procedure that I explained to you for the numbers that send you spam messages; Furthermore, the Messages app, which I have told you about so far, also has a function to filter the alleged incoming advertisements and the latter is usually active by default.

To check that this is actually the case, do this: from the main page of the application, tap the ⁝ icon at the top right and, from here, tap the Settings item . Now press on the item Antispam protection , then check that the lever of the switch located in correspondence with the item Activate antispam protection is moved to ON and, if the lever is set to OFF , remedy by pressing on the switch itself.

As an alternative, you can try blacklisted apps made up of numbers from “known annoyances “, such as Truecaller , which I also told you about in my tutorial on how to block calls from call centers .

As an alternative to what I have shown you above, if yours is a Xiaomi phone , you can also use the Block List function of the MIUI settings to block numbers that send spam messages. To use this function, tap on the gear icon that you find in the notification area, on the home screen or in the app menu and, once the Android settings are open , go to Apps> System app settings> Security> Block list .

In the last screen that opens, make sure that the switch located next to the Block List item is active and, if not, tap on it to activate it. Subsequently, first press on the item Blocked numbers and then on the item Add . Then select the wording Add a phone number , type the number you want to block in the compilation field and to conclude, tap the check icon located at the top right.

Finally, I would like to point out that the default applications for SMS of some smartphone brands are integrated with options for protection from harassing messages based on keywords. For example, if you are using a Samsung phone , you can take advantage of this feature by starting the default Messages app and going to > Block messages> Block phrases and then typing an appropriate keyword (eg “offer” or “discount “ ) In the specific compilation field. For other alternative solutions to avoid receiving unwanted messages, I refer you to my tutorial on how to block SMS on Android .

How to block unwanted messages on mobile: iPhone

Do you want to know how to block unwanted messages on mobile in the specific case of iPhones ? No problem, I’ll settle you immediately. Even the phones of the Cupertino giant have a convenient function for blocking SMS. To use this, open the iOS settings by pressing on the gear icon that you can find on the home screen or in the App Library of your device.

Once this is done, press on the Messages item and then proceed by tapping on the Blocked Contacts item . At this point, press on the Add item , choose the contact you want to block from the list of those available and that’s it. How do you say? Is the phone number that sends you harassing SMS not saved in your device’s address book ?

Then do this: start the Messages app by pressing on its icon (a balloon on a green background), then tap on the preview of the last message received from the number you want to block. Press, therefore, on the phone number you see above and then tap on the Info button and then on the Block contact item : you will no longer receive messages from the selected number.

Please note, however, that in this way you will no longer receive calls (including FaceTime ) and emails from the number in question. How do you say? Have you thought about it and would like to unblock the contact in question? In this case, go to Settings> Messages> Blocked contacts> Edit and, on the next screen, press the red button next to the number you want to unblock. Finally, confirm by pressing first on the item Remove and then on the item Finish .

By going to the settings menu > Messages> Unknown and spam you can also activate the filter to organize messages from strangers in a special tab and activate the filtering of messages with antispam apps like Truecaller , which I also told you about in my tutorial on how to block calls from call centers . For other workarounds, I invite you to check out my tutorial on how to block my tutorial on how to block advertisements .
