I have a cell phone with an area code where I no longer have any connections or ties. Almost all the spam calls I receive come from that area code. By simply ignoring or blocking calls from that area code, I can avoid nearly all of the spam.

I've enjoyed that state of affairs for over a decade but now I'm moving back to where my area code matches my physical location. I'm sad I'll be losing this easy filtering trick.

On the plus side, iOS and Android now have features for auto-answering and filtering so thankfully I have that.
