I block just about every number from the area code my phone number is in. I haven’t lived there in that area for a long time and 100% of the calls were spam. One day the spammers will wise up and use the area code where I live rather than where my phone is based but so far Number Shield has worked out great for blocking entire prefixes.

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.
