My friend and I would be on the phone while we sent each other emails and we would be shocked at how instantaneously they were delivered. But now that I think about it, it is interesting to think how we weren't equally shocked that our voices were being instantly transmitted over the phone at the same time.
To be fair to you, you may not have understood how much data voice and text each took. An email can have hundreds of words sent in an instant, whereas a phone call is limited to a few words per second.
