He attributed the above growth to couple of things. One was smartphone penetration which, he said will touch 500 million connected users by 2020, as the cost barriers kept getting crossed. "When we crossed the first big barrier- the Rs 10,000 one, we went from 10 million to 150 million smartphone users. The next was about three years ago was the sub Rs 6000 one". Our next price tag we will cross is probably Rs 2000-2500 one," he said.
