how to block spam calls

Hate spam calls? Who doesn’t, right! These things are annoying as hell, and it seems like the problem is getting worse by the day. In this post, we take a look at how to block spam calls, or at least minimize them. But before we do, let’s take a look at the three most common types of spams calls.

The first are telemarketing calls from real companies trying to sell you stuff. Carriers and internet service providers love to use them in hopes of luring consumers away from the competition. Then there are robocalls, which are automated phone calls with pre-recorded sales messages. They are also frequently used for political campaigns, charitable causes, and more.

Lastly, there are scam calls from shady characters trying to take advantage of you. They pretend to be FBI, CIA, or bank employees and try to get you to reveal your financial or other sensitive data. For more details on these scam calls, check out our dedicated post on this topic that reveals some of the most common phone scams to look out for.

So, how can you protect yourself from spam calls? You’ll find the four best methods to use below.

Block spam calls with apps and carrier services

The best way to block spam calls is with dedicated apps, which rely on databases of millions of numbers. Whenever you get a call from a number listed in the database, the app will warn you with a message displayed on your screen. Alternatively, it can also send the call to voicemail so you don’t have to deal with it at all.

There are a number of apps like these available in the Play Store — some are free, while others require a subscription. You can check out a few of the best ones below:

Additionally, the big four U.S. carriers all offer apps and services to help their users fight unwanted calls. Features differ from carrier to carrier, as does pricing and availability. Most work the same as the apps described above, which means they’ll notify you when you get a spam call or block it so it won’t even reach you. You can check out what each carrier has on offer via the links below:

Keep in mind that while apps, as well as services offered by carriers, are the best way to block spam calls, they aren’t perfect. They won’t completely eliminate these unwanted calls, but they will greatly reduce them.

Block spam calls one by one

If you’re getting harassed by just a few companies or individuals on a regular basis, the easy way to block unwanted calls is to block their numbers. To do so, all you have to do is open the phone app on your Android device, long press on a number that keeps calling you, and tap on “Block”. That’s it! Keep in mind the process can slightly differ from device to device. 

This is a quick and easy solution, although it’s not the best if you’re getting tons of spam calls from different numbers — blocking numerous numbers each day can get annoying. If that’s the case, opting for a dedicated app — as described in the section above — is a better method.

Block spam calls by only allowing calls from your contacts

Another way to win in the battle against spam calls is to block all numbers except for those in your contacts list. Sure, this might be an extreme measure, but it will get the job done. The best way to achieve this is to download an app like Calls Blacklist – Call Blocker. It’s free of charge and extremely popular with more than 10 million downloads. But there are many alternatives available if it’s not up your alley for some reason.

Just download the app at the link above, open “Settings”, select “Blocking” and tap on “Block all numbers except contacts”, as shown in the screenshots above. When you receive a call from a number not saved in your contacts, your phone won’t ring, but you’ll be able to see that the call happened within the app. Nice!

This method obviously has a major drawback. You’ll likely miss calls from friends, family members, coworkers, and others who may have changed their number or are calling from a different phone. So make sure you only opt for this measure if all else fails.

Block spam calls by registering on donotcall.gov

how to block spam callsDo Not Call

The FTC runs The National Do Not Call Registry, allowing people who want to block unwanted calls to sign up with their phone number. Companies must respect it, which means they are prohibited from calling the numbers the registry contains.

However, this only applies to telemarketing. By signing up, you shouldn’t get any of those annoying calls from ISPs and other companies trying to sell you stuff, but you can still get political, survey, and other similar calls. Signing up also won’t get rid of scam calls, as shady characters normally don’t care much about the law.

Getting your phone number listed in the registry is fast and free — you can sign up via the button below.
