Mr. Number is a 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.

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 you don’t want to allow to contact your phone. An ad-free premium version is also available for about $2.

No. You will have to unblock a number to get in touch with it.

No. You can keep on blocking people, scammers, and marketing calls until your fingers fall off!
