2degrees' chief executive Eric Hertz says smartphones could be selling for less than $100 in 12 months' time and within the reach of "value-conscious" consumers.
Hertz said the drop in price would depend on the global penetration of the phones, but guessed they could fall as a low as $100 in a year's time.
"Customers will shift [from feature phones] when there is a sub-$100 smartphone," he said.
Smartphones are devices with advanced computing power and typically have features such as WiFi connectivity, integrated GPS and mobile broadband access.
Hertz said that in 12 months' time, the price of mobile data will also be low enough so that "value-conscious prepay customers" will be happy to pay for it.
