How To Block Unwanted Phone Calls With Truecaller in iPhone

Last updated: March 2, 2015 at 23:41 pm

Instead of going through the elaborate process of blacklisting a phone number or using government’s Do Not Disturb / Do Not Call registry feature (it is different for every countries), you can use Truecaller app on your iPhones, iPads and iPod Touches.

Using this free app, which was updated in February (2015), you can quickly block all the spam calls that makes you go crazy. And there’s more: Truecaller will also identify calls that should be blocked in your area and gives you a list of names (with phone numbers).

All these data can be used to your advantage. In fact, we found that blocking phone calls on our iPhones from those telemarketers and god-knows-what spams callers made our life a little more easier. And in this how-to tutorial, we will explain you everything you need to know to get started with Truecaller.

Truecaller App For iOS: Why It’s Worth It!

If you haven’t used Truecaller before, here’s a quick little fact: Truecaller is downloaded by over 100 million people. It’s a free app that will track the caller ID name (when you insert the unknown phone number) and block phone numbers so you cannot receive future calls from them on your iOS device.

Here’s an example of how I use Truecaller daily: Sometimes I could never pickup phone calls – and I quickly launch the Truecaller app to find the name of the person. And if I know them, I return the call.

Note that Truecaller for iPhone is absolutely free to download. There is a premium version as well – and it costs $1.99 per month. You can use Truecaller Premium to get more features although they may not be required at this point of time.

If you like what Truecaller does, upgrade to the premium version.

Truecaller can be downloaded on your iPhone by going to the App Store and searching for “Truecaller” (the full name is: “Truecaller: Number Search & Block”). Or you can visit our page for more info: New Truecaller Update for iOS 8

How to Block a Phone Number in Truecaller App

Step 2: Slide your finger from bottom to top (Slide to Activate).

Step 3: A “Permission needed” popup window may appear asking you to give permission to Truecaller to read your contacts. Tap on “Let’s do it” (if you select “Later”, Truecaller will not be able to activate the blocking feature on your iOS device)


Step 4: Toggle the Contacts switch to give Truecaller access to your iPhone’s contact.

  • Oh my…

    The app requires access to your Contacts…no way I’m doing that.
    The app doesn’t really block calls at all..because Apple doesn’t allow it.
    Caller ID is not real time….you have to go to recent call history to see who’s calling.
    Very misleading article.
