Table of contents

In today’s digital age, mobile phones have become integral to our daily lives, profoundly influencing our communication habits. However, the increased reliance on mobile technology brings a significant challenge: the prevalence of unwanted calls. According to the Federal Communications Commission (FCC), U.S. consumers receive approx. 4 billion robocalls per month.


Robocalls are not just annoying, but they can be dangerous, too. While some are legitimate, such as appointment reminders from healthcare providers, many are unsolicited and potentially harmful. Scammers can use these automated calls to trick you into stealing your money or personal information. The key to stopping robocalls is recognizing their patterns and employing effective countermeasures.

What Are Robocalls?

Robocalls are automated phone calls that deliver pre-recorded messages. These calls are made without human intervention. Telemarketers and scammers often make robocalls via auto-dialer software to reach large numbers of people at once.

Every day, millions of robocalls affect mobile users from all around the globe. There are more robocalls nowadays because they’re cheap to make. Moreover, technological advancements have also aided scammers for callers to mask their identity and location, a tactic known as caller ID spoofing. This spoofing has made blocking robocalls challenging as it disguises the call’s true source and the scammers’ identity. That’s why every phone user must know how to stop robocalls to prevent falling into the traps of scammers.

Types of Illegal Robocall

Scammers use different types of illegal robocalls to try to get your personal information. One might pretend to be from a bank asking for your account details, while another might say you won a prize to get your personal information.

Call Spoofing

Call spoofing happens when scammers change their caller ID to hide their real number. They trick you into thinking the call is from someone you can trust, like a local business or a government agency. 

Charities Calls and Scam

Callers pretend to be from a charity and ask for donations. People are more likely to give money if they think it’s for a good cause. Scammers take advantage of it to collect money from you. But the money doesn't go to any actual charity.

False Offers and Giveaway Calls

Another type of robocall is that the scammer promises you a prize, discount, or a special offer, but to get it, you must provide personal details or pay some fees. Most people easily fall into the trap of being excited to get a deal or big prize.

Free Trial Scam

You’re offered a free product trial in the free trial scam, but there’s a catch. They often ask for your credit card details for “shipping” or “handling,” then charge you without clear consent. This is one of the most popular robocalls, as scammers believe no one would refuse free things.

Chinese Robocalls

Chinese robocalls often target Chinese-speaking communities, threatening them with immigration or legal issues. These calls create fear and urgency among those who think they might be in trouble. As a result, they do what the caller has asked for.

IRS Scam

In the IRS scam, the caller pretends to be from the IRS and claims you owe taxes. They threaten legal action if you don’t pay immediately. This type of scam is typically effective as people are often scared of getting into trouble with the IRS.

Debt Collection Scam

In debt collection scam, callers claim you owe money for a debt and must pay immediately. They might even have some of your personal information to sound convincing. Unfortunately, most people pay money due to the fear of the legal consequences, even if the debt isn’t real.

Are there any legal Robocalls?

Blocking robocalls is certainly crucial to protect ourselves from scammers. But before doing that, you must also be careful about what type of robocall you want to block. Not all the robocalls are harmful. In fact, some of these calls are both legal and beneficial. Such calls are made for good reasons and follow the law.


For example, a legally automated call might be a message from your child’s school about a sudden closure or a call from your doctor’s office reminding you about an appointment. These calls are meant to give you important information quickly and easily. So, while it’s essential to guard against scam calls, you should also be aware of good robocalls.
