I've paid $40/year for RoboKiller (the source of the data in this article) since 2020, and consider it worth every penny. For reference, I was a long-time Pixel user before then who enjoyed the Google Assistant call filter. It's not quite as good as Google Assistant (it's based on call forwarding) but by far the best solution on iPhone, and it filters SMS spam as well as calls.
