Why You Should Block Spam Calls on Android
Spam calls can waste time and cause financial risk. Some calls try to steal your personal information. Others are fake offers or unknown promotional schemes.
You may get robocalls or calls from fake banks. Some spammers even use your phone number wrongly. Spam calls disturb sleep, meetings, and even peaceful evenings.
Spammers find your number in many tricky ways. They create fake contests, offers, or even charity drives. Sometimes businesses sell your number to data agencies.
Telemarketers then use that data to call you. They try to sell loans, cards, or fake prizes. Be careful where you share your phone number online.
Use DND Service to Block Spam Calls on Android
India offers a free DND (Do Not Disturb) service. This blocks telemarketing and spam calls at the source. You don’t need an app or any extra tool. DND is available for all telecom operators in India.
Here’s how to activate DND on your number:
- Open your SMS app on your Android phone.
- Type START and send to 1909 for DND.
- You will get reply with call category codes.
- Reply with codes for types of calls to block.
- DND activates in 24 hours after confirmation message.
You can also activate DND using operator apps:
- Jio Users: Open MyJio app → Settings → DND.
- Select spam types you want to block easily.
- Airtel Users: Visit airtel.in/airtel-dnd.
- Enter OTP and choose spam categories to block.
- Vi Users: Visit discover.vodafone.in/dnd.
- Fill in your number and select unwanted call types.
- BSNL Users: Send SMS “start dnd” to 1909 directly.
DND will not block important alerts or delivery updates. You still get messages from banks and e-commerce sites.
Use Phone Settings to Block Spam Calls on Android
Most Android phones have built-in tools for spam filtering. You can block unwanted calls directly from the Phone app. This method is free and works on all Android versions.
Steps to filter spam using Google Phone app:
- Open the default Phone app on your device.
- Tap the three dots at the top-right corner.
- Go to Settings → Caller ID and Spam option.
- Turn on Filter spam calls and See spam ID.
These tools silence calls marked as spam or unknown. They may block real numbers, so be a little careful. You can also keep only the caller ID feature active.
To manually block a number on Android device:
- Open your Phone app and go to call history.
- Tap and hold the number you want blocked.
- Choose “Block” or “Report” from the menu list.
- This stops the number from calling you again.
Manual blocking is helpful for repeated spam numbers only. It’s not useful for changing or random spam numbers.
Pixel users can use special feature called Call Screen:
- Google Assistant answers unknown calls on your behalf.
- It asks why the caller is trying to reach.
- Spam and robocalls are rejected or sent to voicemail.
- Open Phone → Settings → Spam and Call Screen.
- Go to Call Screen and enable for all categories.
- Select Automatically screen and decline robocalls option.
This feature works only on Google Pixel phones currently. Also, it is available in only some selected countries.
Use Carrier Services and Apps to Block Spam Calls on Android
If phone settings don’t work, use your telecom apps. Some telecom companies offer advanced tools for spam blocking. These tools work better than manual blocking and settings.
Here are some apps available in India and abroad:
- Jio Security: Offers spam alert and number blocking tools.
- Airtel Call Manager: Allows only chosen people to call.
- Vi Call Filter: Filters unknown numbers and warns users.
- BSNL DND Settings: Uses codes and filters for call blocking.
Popular international carrier apps include:

- Gives you proxy number to protect real number.
- Premium plan has voicemail-to-text and call blocking tools.
- Verizon Call Filter (USA): Identifies robocalls and filters them fast.

Although made for other countries, similar features exist in India. Use your mobile operator’s app or call settings for help.
Try Third-Party Apps to Block Spam Calls on Android
If nothing works, third-party apps can block spam too. Install these apps from Google Play Store for protection. Choose trusted apps that respect your privacy and data.
Top apps to block spam calls on Android phones:
- Truecaller: Very popular in India for blocking spam calls.
- Shows caller name even if not in contacts.

Many of these apps use crowdsourced spam reports and AI. But some may sell your data to advertisers or companies. So, read the privacy policy before giving full permissions.
Use third-party apps only if other options don’t work. Built-in filters and DND should be your first choice.
Extra Tip: Report Spam Calls for Better Protection
If you still get spam, report the number officially. In India, you can report spam to your telecom operator. In the US, users can report to the FTC (Federal Trade Commission). Reporting helps authorities take action against fraud callers.
To report in the US:
- Visit reportfraud.ftc.gov.
- Fill the form with date, number, and spam type.
- FTC investigates and may take action if needed.
