Yea, im vzw too and I've been getting a spam call from random area codes about every other day. You guys Colorado residents? Let's figure this out, yea?!
just called my cell. who knows what they want as I didnt answer. Im in MI. I called back a few times and got fast busy. Then actually started ringing and I let it ring and ring and ring. Maybe they cant call out cause I'm ringing in. good.
