| How to Permanently Block Annoying Callers Without Third-Party Apps |
Getting repeated calls from unknown numbers, telemarketers, or spam callers can be very frustrating. Many people rush to download third-party apps to stop these calls, but the truth is: you don’t need extra apps. Your smartphone already has built-in features that let you permanently block annoying callers with just a few taps.
In this guide, you’ll learn how to block unwanted numbers on Android and iPhone without installing any additional apps.
Why Block Callers Without Third-Party Apps?
- Security: Third-party apps often require access to your contacts and call history, which could risk your privacy.
- Battery saving: Extra apps run in the background and drain your phone’s battery.
- Free & easy: Both Android and iOS already have caller blocking features, so you don’t need to pay for or install anything extra.
How to Block Callers on Android
Most Android devices (Samsung, Infinix, Tecno, Xiaomi, etc.) have built-in call blocking. The steps may vary slightly depending on your brand, but the process is similar.
Method 1: Block from Call Log
- Open your Phone app.
- Go to Recent Calls or Call History.
- Tap and hold the number you want to block.
- Select Block/Report Spam or Block Number.
- Confirm, and the number will be added to your blocked list.
Now, the blocked caller won’t be able to reach you again.
Method 2: Block via Phone Settings
- Open the Phone app.
- Tap the three dots (menu) at the top-right corner.
- Select Settings → Blocked Numbers.
- Tap Add a Number and type the unwanted number.
- Save, and the number is permanently blocked.
How to Block Callers on iPhone (iOS)
Apple also provides a quick way to block spam calls without extra apps.
Steps:
- Open the Phone app.
- Go to Recents.
- Find the number you want to block and tap the “i” icon next to it.
- Scroll down and tap Block this Caller.
- Confirm by selecting Block Contact.
The number will now be blocked, and they won’t be able to call, text, or FaceTime you again.
Enable “Do Not Disturb” Mode
If you keep getting calls from unknown numbers, you can take it a step further by enabling Do Not Disturb mode:
- On Android: Settings → Notifications → Do Not Disturb → Allow Calls From (set it to Contacts only).
- On iPhone: Settings → Focus → Do Not Disturb → Allowed Notifications → People (select contacts you trust).
This way, only your saved contacts can reach you.
You don’t need to rely on third-party apps to stop spam callers. With the built-in blocking features on Android and iPhone, you can easily block annoying numbers permanently and enjoy peace of mind.
