In the News A few months ago, I wrote an article about comments, in which I said, among others things, that Twitter can never replace comments because not only is it effectively a one-to-one communication channel, Twitter messages are also far too short to foster any form of coherent conversation. Over the weekend, a silly link-bait story illustrated my point perfectly.

The size of SMS is low because it sits on the back of the control signals that are always being sent from phone to tower. There isn't any more space to make them larger unless you send them as data, which then isn't "free" bandwidth (from the carrier point of view). So yes it is left low on purpose but nothing to do with low signal conditions.

Does this mean that in effect, carriers barely pay an extra in terms of bandwidth for every SMS message that is being sent and that they gently charge a hefty price for ?

This is even worse than I thought ! ;)

No, it means it does not use any bandwidth between the cell tower and the cell phones, since the SMS is passed inside a message that is send anyway by your phone.

However, the carrier still have to pay for transmitting your SMS from your tower to your recipient tower, and whether that cost 10cents or not, is debatable.

Also, SMS can send more than 140 characters (at least in Europe), I regularly do that. But then of course it does cost you "ceil(characters_count/140)*sms_cost" ;)
