This feature was already available for Android. It has been specially designed to avoid the hassle of spam calls. The user does not have to worry about getting a spam call.
If you are an iPhone user and want to use this feature, then you will have to activate the Auto-block Spam (Auto-block Unsolicited mail) feature. This option will be available by going to ‘Give protection to’ option. After this, whatever spam call you receive, Truecaller will identify it and automatically reject the spam call.
This feature can be useful for those people who are very troubled by spam calls. Currently this facility is available only for Truecaller premium subscribers. The company has not said anything about when it will be rolled out for other users.
The auto-block spam feature has been brought to iOS 18. Users who have updated to iOS 18 can use it on the latest Truecaller version 13.12. However, currently it is available only for premium users. According to reports, Truecaller is also developing many more features for iPhone users.
