Activating CleanBrowsing on your iPhone is pretty simple. Just follow these steps and in less than 5 minutes you will have a kid-safe iPhone for your kids and family to enjoy (note that instead of using Google's DNS server (184.108.40.206 & 220.127.116.11), you need to use our Safe DNS Servers: 18.104.22.168 (or 22.214.171.124).
1. To change the DNS servers on your iPhone or Ipad, you have to go to Settings->Wifi. Inside the Wifi page, you will find a list of all your networks, where you have to choose the one your device will connect to.
2. Once you click on the Wifi connection (generally the one at the top), you will find multiple networking settings, including IP, Subnet, Router, etc. You can keep these as is and find the DNS option.
3. Remove the current DNS servers configured and add 126.96.36.199 (or 188.8.131.52). That's all you need to do to enable CleanBrowsing on your iPhone.
