How to Block Spam Calls on Android and iPhone?

Spam calls are very annoying and often highly risky. Recently, they have increased a lot alongside smartphone and internet scams. You must know how to block these spammers and stay safe from scams. Here’s how to block spam calls on Android devices and iPhones permanently.

There are several ways spammers can get your contact number and frustrate you by calling repeatedly. In an era where you have to use your phone number to register here and there, it becomes quite impossible not to give your number to any third-party source. The only thing you can do is to block the spammers.

Fortunately, blocking spam calls and robocalls on Android devices and iPhones is possible. There are several ways to do that. You can use any suitable method to get away from the spammers and keep your call history clean. Let’s move to the learning part.

Register Your Phone Number In Do Not Call List:

Citizens in the United States can register their phone numbers in the National Do Not Call Registry by the FCC. By doing so, you are opting out of telemarketing calls, and the spam calls you receive regularly will reduce significantly. Entering your number in the Do Not Call list is simple and free.

Follow these steps to register your phone number in the National Do Not Call Registry:

  • Visit in a browser of your choice.
  • Now click on “Register.”
Register On DND Registry
  • Next, click on “Register Here.”
Register Here
  • Next, enter your phone number and your email address, and click on “Submit.”
Enter Phone Number
  • You can enter up to three phone numbers at a time.
  • Next, click on “Register.”
  • The FCC will send you an email to verify it’s you.
  • Go to your email inbox and open the mail.
  • Click on the verification link to verify your details.
Verify Number
  • Finally, you’ll see a prompt stating that registration is complete.

That’s it. This method will help you block spam calls on Android and iOS devices, especially robocalls. However, it isn’t a foolproof method, and you may still receive unwanted calls. You will also have to use additional device-specific methods shared below to block them.

How To Block Spam Calls On Android?

There are several ways to block spam calls on Android phones like Samsung, Pixel, OnePlus, Xiaomi, Oppo, or any other smartphone. We have shared the best ways below.

1. Block Spam Calls Using Google Phone Dialer:

If you use the Google Phone app on your Android device, you can use the dialer’s built-in spam filtering feature to block unwanted calls and robocalls. Here’s what you have to do:

  • Go to the Phone app.
  • Now tap on the three dots in the upper-right corner.
  • Tap on Settings.
Google Dialer
  • Next, tap on “Caller ID & Spam” in the Assistive section.
  • Finally, turn the “Filter spam calls” toggle on.

Note: When you enable spam filtering on Google Phone, you may miss calls from your delivery persons. When we tried the feature to block spam calls, we realized that it also marks the parcel and courier delivery numbers as spam and blocks them immediately.

That’s it. This feature is also available on Android phones with dialer apps, like Samsung and OnePlus. You can also use the spam filtering option to block spam calls on Samsung phones.

2. Block Spam Numbers Manually:

If you don’t want important calls to be marked as spam by your dialer app’s filtering, then another option is to block the spam numbers manually. This method is useful when repeatedly receiving spam calls from the same few numbers. Follow these steps:

  • Go to the Phone app.
  • Find the spam number from the call log.
  • Long press the number and choose “Block/Report Junk.”
Block Report Junk
  • Finally, tap on “Block.”

That’s it. Do this with all the numbers that are used for spam calls. Whenever you receive any spam call, just cut it, and put it into the block list. However, do this with care as you may put an important contact in the block list accidentally.

3. Use Third-Party Apps To Block Spam Calls:

There are several third-party apps available on the Play Store that you can use to filter and restrict spam calls. Truecaller is one of the most popular apps to block spam calls. It’s also one of the oldest ones for the purpose and has a very good reputation. However, some users find it too despotic.

This is because it required a lot of permissions on your phone and was also involved in a major data breach in the past. That’s why people are often seen searching if Truecaller is safe to use.


You can also find some good Truecaller alternatives like Call Blocker- Caller ID, Call Blacklist- Call Blocker, Should I Answer?, etc. These apps are available for both Android devices and iPhones.

The problem with using third-party apps to block spam calls is that there’s a possibility that someone from the company may end up sharing or selling your data. Another risk is that your details will become public if the app experiences a data breach.
