Finland's Nokia, once the undisputed leader in mobile phones, has been struggling to respond to the challenge from smartphone makers such as Apple and Samsung.
Company has plans to launch its latest 4G enabled phone Lumia 830 priced at around Rs 26,000 before taxes by Oct.
Microsoft has launched the Lumia 830, 735 and 730, priced at 330 euros (about Rs 26,190), 219 euros (about Rs 17,370) and 199 euros (about Rs 15,800), respectively, as it tries to build on its acquisition of Nokia's mobile division earlier this year.
