    If you don't want to install third party applications, you can open the app Contacts (o People) of Android, select the contact to block and first press the icon of pencil at the top right and then on the button on the button (...). After that you have to activate the option All calls to voicemail and all calls received from the selected contact will be automatically redirected to voicemail. If the voicemail service is not active, the number will simply be busy.

    On some smartphones, such as Samsung-branded ones, a function is available to block calls without diverting them to the answering machine. To use it, open the dialer (the screen where telephone numbers are dialed), presses the button Menu/Other che si trova in alto a destra e seleciona la voce Settings from the menu that appears. Then go up Other settings e seleciona le voci Call barring> Voice call.

    On Android 6.0 and above, you can also block a number by opening the call history, keeping your finger pressed on the contact to be blocked and selecting the appropriate command from the menu that opens.

    Applications to block calls on Android

    How to block a mobile number

    If you use an Android smartphone that does not include the call blocking function, or in any case you prefer to turn to third-party applications, you can try Calls Blacklist. It is a real "black list" that automatically hangs up the phone when you receive calls from unwanted senders.

    To use the application, download it for free from the Play Store, start it and press on "+" button located at the bottom right. At this point you can choose whether to block a number included in the call history (by choosing the option From the call log), from contacts (choosing the option From contacts) or if enter a number manually. If you want to block all numbers starting in a certain way (e.g. the prefixes of tolled numbers) you can choose the option It starts with.

    Done! At this point, all the numbers you have entered in the blacklist will no longer be able to call you. Trying to do so, in fact, they will receive the busy signal (after a free ring) and you will not hear the mobile phone ring, but you will receive a notification about the blocked call.

    In case of second thoughts, you can easily remove the numbers previously entered in the blacklist by selecting them from the app screen and pressing the button Clear.

    Please note: Calls Blacklist also includes an additional function to block SMS, but be careful because on Android 4.4 or higher it does not work properly. It can only be activated if you turn the app into the default application for managing messages and this can lead to additional costs when sending SMS.

    Block anonymous mobile numbers

    Is there anyone persistently calling you anonymously? You can find out his identity, and then block his phone number, using Whooming, a service that uses the call forwarding technique to reveal the real number of the anonymous caller. I have well explained to you how to use it in my tutorial on how to find out the private number.

    Alternatively, if you have an Android smartphone, you can install an application such as Should I Answer? and automatically block all anonymous calls (as well as those from call centers, scammers and other known annoyances). I have explained to you in detail how this app works in my tutorial on how to block a number on Android.
