NumberShield lets you block wildcards while letting your contacts through. It won’t let you specify a ‘global’ wildcard, but I find blocking my own area code is generally sufficient. Most scammers and spammers spoof your local area code these days, and Nomorobo is pretty good at filtering out those that don’t. Between those two apps, I go months without unwanted calls. I used to get them daily.
