the telegram bot is not available anymore but there's a workaround, if you make an account on zlib website and go to "edit profile" page there's a button at the bottom to get a personal telegram bot
personally, I use NextDNS which offers 300,000 queries per month, it's basically a dns server that doesn't let your phone connect to ad servers. you can put it's dns address in your phone settings, pretty easy to use.
if however you want something without limits, you can use dns.adguard.com (just put it in private dns settings in your phone.
that's only for android though, Idk about iOS as I don't own an iPhone but it should be possible on iOS too.
