How to Block Unknown Number Phone Calls By Country Code

Many TechWelkin readers have told us that they are getting a lot of spam phone calls. Some people get such calls where the phone number is unknown or hidden. Some other people get these unwanted calls from international numbers (One Ring Scam). A few folks have reported that they are getting as many as fifty such calls in one day. These annoying calls can wake you up in the middle of the night or may interrupt an important meeting. So, how do you deal with it? Well, you can simply block the troubling phone number. But callers often call their targets from different numbers and you will get tired of blocking calls from hundreds of numbers.

This is the reason why people often think of blocking calls by a specific country code. If you could blacklist an entire country, you will not receive any call originating from there. This makes it much easier to get around the problem of blacklisting hundreds of specific phone numbers.

But how do you block calls by country code? For Android phone users it is pretty easy! In this tutorial, we will tell you how to go about it.

Block Calls by County Code

Take the following steps. Please note that because Android gets customized by various phone manufacturers, options could be slightly different in nomenclature:

1. Open Settings
2. Go to Call Settings > Call Rejection > Auto Reject List > Create
   
3. Now create a list of phone numbers from where the calls will be automatically rejected by your phone. Enter phone numbers, or part of the number that you’d like to block. If you want to block calls by country code, just enter to country code with a plus sign prefix (for example, enter +234 to block all calls from Nigeria)
4. Change Match Criteria to Starts with
   
   
5. Save the list

This is an easy method to quickly block all the calls from a particular country. In our article on One Ring Scam, we have given the country codes of many countries where from such spam calls originate. You can block any or all of these countries if you want.

But remember, once you set this option, you will not be able to receive any calls from the blocked country. If you have any valid reason of getting a call from that country, think twice before blocking the entire country. If you have friends, relatives and/or business contacts in that country — you might want to consider this aspect as well. But if you have no reason whatsoever to get a call, just go ahead and block the country whose calls are giving you troubled sleep.
