Number Shield looks brilliant! I get a lot of spam calls from my area code and three number prefix. I don’t have any legitimate contacts with a phone number like that, so blocking the whole range looks like a good solution. However, I don’t expect any urgent calls from anyone outside of my contacts so I was able to fix the problem by enabling iOS’s Silence Unknown Callers feature.
