"At those hearings, Srinivasan Keshav, a professor at the University  
of Waterloo in Ontario and an expert on mobile computing, presented a  
detailed analysis of all the expenses that carriers incur in handling  
SMS messages. He showed that the wireless channels contribute about a  
tenth of a cent to a carrier's cost, that accounting charges might be  
twice that and that other costs basically round to zero because  
texting requires so little of a mobile network's infrastructure.  
Summing up, Keshav found that a text message doesn't cost providers  
more than 0.3 cent."
