Spam calls are a nuisance, and they can even be dangerous. Scammers often use spam calls to try to trick people into giving them personal information or money. Thankfully, there are a few things you can do to block spam calls and protect yourself from scammers.

How do spam calls work?

Spam callers use a variety of methods to make calls. Some spam callers use automated dialers, which can dial millions of numbers in a short period of time. Other spam callers use VoIP (Voice over Internet Protocol) technology to make calls from computers.

Spam callers often use spoofed phone numbers, which makes it look like they are calling from a local number or a well-known company. This can trick people into answering the phone, even if they don't recognize the number.

What are the different types of spam calls?

There are many different types of spam calls, including:

Sales calls: Spam callers often use sales calls to try to sell people products or services, such as insurance, credit cards, and home security systems.

Scams: Spam callers also use scams to try to trick people into giving them personal information or money. Common scams include tech support scams, investment scams, and romance scams.

Political calls: Spam callers also use political calls to try to influence people's votes.

How to block a spam caller

There are a few things you can do to block spam calls:

Use your phone's built-in spam blocker. Most smartphones have a built-in spam blocker that can automatically block spam calls. To enable the spam blocker, go to your phone's settings and look for the spam filtering option.

Use a third-party spam blocker app. There are a number of third-party spam blocker apps available for both Android and iOS devices. These apps can be more effective than the built-in spam blocker in blocking spam calls. Some popular third-party spam blocker apps include Hiya, Truecaller, and RoboKiller.

Block spam numbers manually. If you are getting spam calls from the same few numbers, you can block them manually. To block a number, open the call log on your phone and tap the block button next to the number you want to block.

Don't answer calls from unknown numbers. If you don't recognize the number that's calling you, don't answer it. If the call is important, the caller will leave a voicemail.

Additional tips for blocking spam calls

Here are a few additional tips for blocking spam calls:

Keep your phone's software up to date. Software updates often include security patches that can help protect your phone from spam calls and other malware. Make sure to install software updates as soon as they're available.

Report spam calls to your carrier. Most wireless carriers allow you to report spam calls to them. To report a spam call, forward it to your carrier's spam reporting number. The spam reporting number varies by carrier, so check your carrier's website for more information.

What to do if you fall victim to a spam call scam

If you think you may have fallen victim to a spam call scam, contact your bank or credit card company immediately. You should also change the passwords to all of your online accounts. If you gave the scammers any personal information, such as your Social Security number, you should place a fraud alert on your credit report and monitor your credit report for any unauthorized activity.

Conclusion:

Spam calls are a nuisance, but there are things you can do to block them and protect yourself from scammers. By following the tips above, you can reduce the number of spam calls you receive and keep your personal information safe.
