How to block incoming calls on iphone by number mask?

Question

iPhone

The bottom line is this: collectors call from [phone]***, the last three digits are constantly changing. Accordingly, just blocking the number every time makes little sense. Is there such an application in the appstore that would block all incoming calls by entering a certain sequence of digits into the subscriber's number? I couldn't find it myself. There are applications that block calls, this is understandable, but exactly blocking, as I wrote?

Answer 1

I don't think so. But you can mute all calls that are not from the address book. Here is the instruction => https://support.apple.com/ru-ru/HT207099
I recommend installing several of the blockers at once. They work in conjunction and I already forgot the last time I did not catch spam with them.
