Truecaller adds SMS spam filtering functionality on iOS
Truecaller has
updated its iOS app to add support for SMS filtering. After updating to the
latest version the app will attempt to filter spam messages and separate it
into a second folder.
The addition of this feature is courtesy a
new feature in iOS 11 that enables third party applications to filter incoming
messages and sort them into a separate SMS Junk tab that appears in the
Messages app when you use an app that lets you filter messages. These
applications can use keyword detection or machine learning algorithms to figure
out if incoming messages are spam or useful and then sort them accordingly.
Truecaller is now tapping into this new
functionality in iOS 11 to enable this feature. Once you update the app, it
will guide you how to enable it (Settings > Messages > Unknown & Spam
> turn on Truecaller). I'm not quite sure if Truecaller uses simply keyword
filtering or machine learning to determine if an incoming message is spam or
not and we will have to use the app further to determine how effective it is at
blocking spam and allowing actually useful service messages through.
Update: After a day of use the app is yet to
block any spam SMS. You are better off installing something that actually works
like SMS Shield.
