Nokia hopes the four new phones — the Lumia 720, Lumia 520, Nokia 301 and Nokia 105 — will help it maintain and perhaps build on its position as the No. 2 maker of cellphones worldwide behind Samsung and fend off challenges by two Chinese manufacturers, Huawei and ZTE, analysts said.
Stephen Elop, the Nokia chief executive, said the new, lower-priced Lumia handsets would give the company a full array of smartphones it had been lacking.
“These are less expensive devices, but they will move in much larger volumes,†Mr. Elop, a former Microsoft executive, said in an interview.
The Lumia 520, selling in Europe for 139 euros, or about *183, and*179 in the United States, is priced 25 percent lower than Nokia’s least expensive smartphone, the Lumia 620.
