My mobile number has an area code for a place I haven't lived since 2012. I'd thought about changing it to match my new location, but then I realized that since I'm no longer in contact with anyone in my old area, I'm able to safely assume any number calling from it is a robocall.
I get several of them a day. So I think I'll keep my old number.
So I think there's a possible solution: Pick a new mobile number with an area code for a place you don't know anyone and have no reason to receive calls from.... then block/ignore all calls originating from it.
Whatever spam blocking I get from Google Fi + latest Android on a Pixel phone has completely eliminated spam calls. I went from getting 3+ per day to zero.
