Nokia has been aggressive about introducing the Windows Phone experience in the budget segment in India. The new Nokia Lumia 510 smartphone is quietly listed for Rs 9,999 at the online retail site Flipkart while the official Nokia Online Store is yet to put a price tag on the device. The new Nokia Lumia 510 smartphone comes with an 800 MHz mobile processor and runs Windows Phone 7.5 Refresh. This smartphone is intended to be Nokia’s most affordable Windows Phone device for the masses.
The budget friendly Nokia Lumia 510 smartphone comes with a 4 inch touchscreen display with 480 x 800 pixel native resolution. This display offers Pixel density of 233 pixels per inch. Nokia has packed a low power 800 MHz Qualcomm Snapdragon S1 MSM7227A mobile processor with 256 MB RAM to make the phone run smooth. At its rear, the phone has a 5 Megapixel camera with f/2.4 aperture, LED flash, and it can be expected to deliver modest imaging quality. There is no secondary camera in the front but this phone has a dedicated camera key on the right side 
The surprising fact of this smartphone is that there is no micro SD card slot and the phone arrives with just 4 GB on board storage. Although Microsoft does offer SkyDrive cloud storage, not many Indians will be interested in using it.
Other features of the Lumia 510 include FM radio, Bluetooth 2.1, WiFi, micro USB port, accelerometer, ambient light sensor and 3.5 mm audio port. Another surprise for Indian consumers is that the Lumia 510 uses a micro SIM card. Nokia has packed a mere 1300 mAh battery that is said to offer Talk time of 6.2 hours over GSM networks and 8.4 hours over WCDMA networks. We believe, however, that this might be a typographical error and that the respective talk times are the other way around-8.4 hours on 2G and 6.2 hours on 3G.
Nokia Lumia 510 is aimed at the budget segment in India and will be available for about Rs 10,000 at online as well as offline shopping destinations.
