Nokia launched three new phone models on Monday, saying it expected the new 6131 camera phone to become one of the best-selling models in the mid-price range. Nokia said the 6131 would retail for around 275 euros ($326.90), excluding subsidies and value added taxes.

"We believe this will be one of the most sold mid-range phones in the world," Kai Oistamo, head of Nokia's Mobile Phones unit, told Reuters at the 3GSM trade show in Barcelona.

He added he expected the phone to be sold in "tens of millions" of units over its lifecycle.

Nokia also unveiled the 6136 model, with a camera and technology allowing it to connect to wireless network hotspots, which Oistamo said would also retail for about 275 euros. The new basic model 6070 would have a retail price of about 135 euros, Oistamo said.

He added all three phones would start shipping in the second quarter of the year.
