Most of us would agree that the spam calls we keep receiving on our smartphones have proven to be a nuisance for many years now.

Typically, users will tend to get roughly four to six robocalls each day; if you think that you are the only one, you could not be more wrong.

Each day you wake up, you will receive a lot of annoying robocalls.

In today’s time, robocallers have improved their strategy by masking spam that looks like genuine local phone numbers.

In most cases, the spam calls are quite amusing – who would not want to laugh at a robotic threatening voice warning you about a potential arrest due to your pending taxes?

However, you should remember that these continuous barrages of calls are very annoying.

Today, these spammers make use of the internet to fire countless calls.

Even if very few people do fall for the scams, they will still end up making a significant profit, which will easily cover these small expenses.

Today, most Android devices like Google and Samsung smartphones feature in-built options for flagging suspicious robocalls and spam calls.

In the case of a Google Pixel phone, the whole screen will turn red once it detects an incoming spam call.

This is the easiest way of knowing which calls you can answer and the ones that you can avoid.

Alternatively, you can also tap on the three dots on the right corner of your Pixel smartphone; head over to the Settings option, then on Caller ID and Spam.

Here, you will find various filters for spam calls and spam ID.

Most other Android devices have similar features.

As for Apple devices, iOS 13 has come up with a standalone app called Silence Unknown Callers; as you may have guessed by the name, this app will instantly block all callers that are not present in your contact list, have not texted you, or have not been in contact with you.

All such spam calls will straightaway be dumped to your voicemail.

You do not have to download this app separately; you simply need to head over to the Settings, then Phone, and enable Silence Unknown Callers.

Option 5: Make Use Of The Do Not Disturb Feature To Allow Calls From Your Contact List Only

In both iOS and Android OS, you will find a dedicated Do Not Disturb mode.

Once you enable this mode, you will only receive calls from people and businesses that are present in your contact list.

Of course, this method is quite a drastic one as you could easily miss calls from people who are not present in your contact list.

Thankfully, all such calls will be redirected and sent to your voicemail.

Later, you can add that number to your contact list.

However, experts recommend that this option should only be used as a last resort; additionally, you also need to be very meticulous and good about updating your contact list on a daily basis.

Why Do Most Spam Calls Look Like Real Numbers?

Yes, most spam calls look like real numbers.

This can prove to be quite annoying.

This trick is known as neighborhood spoofing; if you are looking for more information, you can head over to RoboKiller to learn more.

Basically, scammers think that any number that matches your local area code (or even the first few digits of the phone umber), the human mind will get tricked into answering it.

Because of this, the trickery also feels more despicable.

What if you receive the call while you are in the middle of a family emergency?

What if you are visiting the doctor or a pharmacy?

Thankfully, most of these spam blocking apps have been improved so that they can easily spot neighborhood spoofing.

According to RoboKiller, its app is a great option for noticing neighborhood spoofing from the start.

Another great option is Nomorobo, whose main focus is to detect neighborhood spoofing.

Tip 1: Always Add Yourself To The Do Not Call Registry

Most telemarketers, in theory, are supposed to celebrate and honor the National Do Not Call Registry.

You can always add yourself to this list simply by heading to the website ( and following the remaining steps as prompted.

After you have signed up and registered as a member, your account at the Do Not Call Registry will never expire or lapse, contrary to some ongoing rumors.

You will also not have to keep re-adding your number to the list or keep renewing it.

You should know that, Do Not Call Registry will not cover surveys, debt collectors, political groups, and charities; it will only cover sales calls.

The same can also be said for the companies with whom you may have been in business.

Of course, you always have the option of telling the telemarketer verbally to stop calling you.

However, there are some types of robocallers and scammers that will not pay any heed to the DNC Registry and choose to ignore it completely.

Since these robots do not answer anyone, using the above-mentioned methods is considered the best choice.

Tip 2: Try To Fool The Robot Into Thinking You Are Not A Real Human

Of course, who has not thought of calling a scammer or a robocaller to swear up and down? However, this anger will only take you so far.

If you want to do any real damage, you need to make the robot caller confused whether they are talking to a real person or not.

Whenever you receive a call from a scammer or robocaller, you simply need to pick up the phone and do nothing.

Do not push any buttons or say anything, even if you receive instructions from the robot.

Eventually, the call from this robot will go to your voicemail or will hang up if you have picked it up by mistake.

You should never put your trust in a robotic voice, even if it sounds like a human.

Tip 3: You Can Lodge A Complaints To The FTC

If you ultimately failed to stop these scammers and robocallers, you can always report your case to the FTC.

While they will be unable to pursue each and every complaint, they will look into the important ones based on the magnitude of the issue.

As mentioned previously, the FTC does take down some of the scam callers.

Of course, you may still end up receiving calls from scammers and robots even after using all these methods.

However, we do hope that this article can at least ease the avalanche of a problem that you are facing.

Hopefully, you will be able to trust your caller ID again once all carriers can get their call verification process up and running.

This will actually help answer calls more often from people on your contact list.
