How can I activate the Clever Dialer spam protection on my iPhone?

If iOS 18 is installed on your iPhone, you can find the option as follows:

1. Go to the Settings App
2. Tap on Apps
3. Tap on Phone
4. Scroll down a bit and tap on “Call Blocking & Identification“
5. Enable the switch for Clever Dialer

On iPhones with older iOS versions than iOS 18, skip step 2.
