Indeed, and Signal has been marketed from day one as a drop in SMS replacement. Initially it even used SMS as the transport for encrypted messages. it was literally called "TextSecure". This is why I have always found the attacks on it using phone numbers to be amusing.
I just had to rotate numbers and get issued a new card recently after my normal replacement one didn't show up in the mail. The teller at my bank said they had dropped embossed cards because no one took rubs of cards (besides people stealing them) these days and that was the reasoning behind having embossed cards in the first place.
