It is not strange that many of us get restricted or unknown calls sometimes, and we often get irritated by irrelevant calls which we don't want to answer.

In today's article, we will familiarize you with all the details regarding how to block all the incoming restricted calls which are usually shown as the "unknown number" on the phone, and we will describe what the restricted calls are and whether we should answer a restricted call or not. Then we can block restricted calls using the built-in options or the third-party Apps in the future.

Some people may ask: "what kind of calls are called restricted calls? Are restricted calls different from other calls?". Well, you will get the answer in Part 1.

Part 1: What is a Restricted Call?

First of all, let's differentiate restricted calls and unrestricted calls: unrestricted calls refer to the calls that can clearly show the phone numbers, while restricted calls are the calls without phone numbers showing on the caller ID or call log, and we can't call back a phone call not knowing the phone number.

When you receive a restricted call, it means that you are being contacted by somebody or one company that does not want himself/herself/itself to be tracked or called back for these or those reasons. Here comes a question - is it necessary to answer a restricted call?

Part 2: Should You Answer Restricted Phone Calls?

People send a restrict call for various reasons, some don't want their privacy left out to people with bad intentions, a restricted call is a good choice when they are not sure what kind of person they are contacting with; others just don't hope to be disturbed by unimportant people and waste time.

Although it is possible that a restricted call is without any harm as it also has some legitimate reasons, we should be careful when we receive a restricted call. After all, many restricted calls are from people with dishonest reasons.

Take the example of scammers, they usually use restricted calls to make robocalls and this way, they have more ease in befooling people and catch a bit more fish with their bait. And popularity of Apps that block such calls is rising due to such scams.

The second example is of telemarketers who employ this practice. These calls from telemarketers are harmless but frequent calls annoy us.

Another but the worst example is of stalkers, criminals, and other dangerously shady people who make restricted calls and tempt people into their traps. In case they harass you relentlessly, you will not even have their number to report to law enforcement agencies, so you should still think carefully before you accept any kind of restricted calls.

So, in a nutshell, there is no answer in "yes" or "no" for this question as it varies from call to call. If we have no idea whether we should answer it when we see a restricted phone call on our phone, we can directly block all restricted calls, then we never need to make a choice. Next, let's learn how to block restricted calls on our cell phones.
