"In 2007, there was almost no data traffic in the mobile networks. In December last year, data passed voice. On average now, there's more data than voice in the mobile networks. And we expect that to double every year for the coming five years. If you double something five times, it becomes 30 times bigger. So in 2015, there will be 30 times more data than voice in the networks."
