when a blocked number tries to send you a text message, it won’t go
through, and they will likely never see the “delivered” note. On your
end, you’ll see nothing at all. As far as phone calls are concerned, a
blocked call goes directly to voice mail. On your end, you’ll get a
special “blocked messages” folder in your voice mail inbox if they leave
a message, but you won’t get a notification they called.
