TCL Plex hands on white in hand phone call up to ear

It’s faster and easier than ever to get in touch with family and friends thanks to Android smartphones. However, we don’t always want to deal with every single call that comes to our phones. Sometimes it’s spammers, strangers, telemarketers, and other unwanted callers. Luckily, you don’t need to worry about those unnecessary pests — go ahead and block ’em!

In this guide, we’ll teach you how to block a phone number from your Android device.

How to block a phone number with built-in call blocking features

Most Android phones nowadays have easy, native ways to block specific numbers. This wasn’t always the case, though, so many OEMs had to build the feature themselves. That means you’ll have to work a little harder to thwart those telemarketers, depending on your device.

Needless to say, we can’t go into detail about the necessary steps for blocking calls on every single phone out there. We can, however, show you how to block callers on most of the top Android devices.

Third-party apps for blocking phone calls

If your Android phone doesn’t have an in-built call-blocking feature, or if it does but you find it lacking, you might be wondering how to block a phone number using another method. Thankfully, you can choose one from the many third-party call-blocking apps on the Google Play Store. Of particular note are Mr. Number, Call Blocker, and Calls Blacklist.

Mr. Number

Mr. Number call blocker

Mr. Number is a free and ad-free Android app that allows you to block unwanted calls and texts on your mobile phone. This app protects your phone from spam, allowing you to block calls from people and businesses.

You can block calls from individual numbers, an area code, and even an entire country. You can also block private and unknown numbers by sending them straight to voicemail and report spam calls to warn other people using the app. Download it via the link below if you want to give it a try.


Call Blocker

Another handy call blocker app that you’d want to try is the free and ad-supported Call Blocker. If you subscribe to the paid and ad-free version, you can enjoy premium features, including Private Space that securely stores private SMS messages and call logs.

Call Blocker pretty much works the same as Mr. Number and other call blocking apps. It will block unwanted and spam calls and even comes with a Call Reminder feature that helps you identify unknown numbers. There’s also a Whitelist available for storing numbers that can always reach you. Hit the button below to download it to your device.


Calls Blacklist

How to block number with Calls Blacklist

Last but not least on our list is the free but ad-supported Calls Blacklist, a straightforward app for keeping a list of contacts that you don’t want to allow to contact your phone. An ad-free premium version is also available for about $2.

To block calls with Calls Blacklist, launch the app and add a contact number to the Blacklist tab. You can add a number via your Contacts, call logs, messages log, or add numbers manually. That’s it — contacts saved under Blacklist won’t be able to call your Android phone anymore.
