"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.
