Blocking phone numbers on Android

Firstly, let’s get this out of the way blocking someone’s phone numbers or SMS messages is an action that is totally done on your end, and the person isn’t going to find out about it unless, of course, they can guess so by calling you again and again and the phone calls don’t go through. 

When you block a phone number, there’s no way it can get through to you. When the person calls, your phone won’t ring and depending on your phone’s manufacturer, you may or may not get a notification that a blocked number contacted you. On the other hand, the person calling you would be told that your phone is busy. 

While blocking a number doesn’t explicitly block them from sending you SMS messages, they won’t see a delivered status on their end. Once again, depending on the manufacturer of your phone and your SMS app, you may or may not have to block them separately when it comes to SMS.

Contacting a blocked number

The story is different when you’re trying to call or message a previously blocked number. You see, blocking phone numbers isn’t a two-way thing. So while you’re still able to call or message the blocked number, as usual, they won’t be able to get back to you unless you unblock the number.
