Finnish operators credited the expansion of the Lumia range in the country for Nokia's strength during the period from April through June. By adding more price points to the Lumia line, Nokia can now cover demand for all economic demographics in Finland. This is pointed out by TeliaSonera’s Communications Director Timo Saxén who notes that Nokia Lumia models now cover the entire range of buyers.
At the low end, Nokia has the sizzling hot Nokia Lumia 520, its top selling phone at the moment. At the high-end is the Nokia Lumia 1020 with its 41MP PureView camera.
