SMS:ing is bigger than (mobile) phone calls in Sweden, especially among young people — all they do is text each other, back and forth, even when calling might be cheaper. It's been this way for years. Key reasons: receiving an SMS is free (I believe this to be true of most countries except the US). Sending SMS as well as making calls is much much cheaper. SMS are usually delivered the moment they are sent.
