The Helsinki-based handset maker said the move will help it meet North American customers' needs and help it build "a more channel-focused organization."
Nokia named Mark Louison head of its device business and president of its North American arm. Tim Eckersley, now head of Nokia's device sales in North America, will leave his job at the end of June. His plans will be announced later, Nokia said.
Nokia said the device sales organization will move most of its support functions from Irving, Texas, to Nokia's corporate facilities in White Plains, N.Y.
"The changes we announced today are designed to align us more closely with our customers in order to drive improved business results in North America," said Robert Andersson, executive vice president, Nokia Customer and Market Operations. "We believe these moves will enable us to reinforce our sales and marketing activities in this important market and allow us to provide our customers with some truly compelling product offerings."
