2.3 trillion SMS will be sent in major markets worldwide in 2008, Gartner predicts. That’s up nearly 20 percent from 2007, while messaging revenues will grow about 16 percent to $60.2 billion. North America will see significant growth, with Gartner saying more than 300 billion messages will be sent in 2008, up from a predicted 189 billion this year. In Western Europe, though, growth is slowing, and the firm says that person-to-person SMS revenues there may peak in 2007, thanks to price cuts and message bundles. To combat this slowing growth in P2P messaging, Gartner says operators should look to social-networking services to drive traffic, as well as mobile search and advertising.
