Nokia has joined forces with Microsoft in an attempt to regain ground lost to the iPhone and Android-based devices.
The deal will see Nokia use the Windows phone operating system for its smartphones, the company said.
It means that Nokia's existing operating systems will be sidelined.
Speaking at the launch of the partnership, Nokia's chief executive Stephen Elop revealed that there would be "substantial" job losses as a result of the tie-up.
Nokia will remain "first and foremost...a Finnish company. Finland is our home and will remain our home," he said.
But job losses around the world, including in Finland, will be inevitable, he added.
Windows first
Speaking about the new partnership with Microsoft, Mr Elop said that "the game has changed from a battle of devices to a war of ecosystems".
"An ecosystem with Microsoft and Nokia has unrivalled scale around the globe," he said.
