NextDNS for the win. You can set it and forget, or tweak it to your heart’s desire. Works on your home network plus on all your devices anywhere in the world. No restrictions. You can tailor settings for each individual device if desired. IMHO, it’s incredibly cheap for an excellent service.
I actually became interested in them simply because where I live, they’re the fastest DNS provider - faster than my ISP, Google, CloudFlare, all I tested over months. The ad-blocking was secondary to me, but now of course I see it as the primary value since it’s so easy to use yet so configurable at the same time.
NextDNS works on cellular, since you install the config on the phone itself. Works brilliantly, anywhere I travel.
