I have this, but recently "local" spam callers have been getting through a lot more. I don't know if they're spoofing or buying up blocks of numbers but most of them have "valid" caller ids in Hiya.
They're spoofing. You might even find SPAM calls for your own number if you look. I got a text from a confused person with the same first 6 digits (area code + part of the number) asking why I called, and had to explain that I didn't.
