Features of Microsoft Lumia 640 and Lumia 640 XL

The dual SIM-Lumia 640 comes with 5-inch HD display, 1.2GHz quad core Qualcomm Snapdragon processor, Windows Phone 8.1 with Lumia Denim operating system, 8 MP rear and 1 MP front facing cameras, 8GB internal memory (30 GB free OneDrive and micro SD support up to 128 GB) and 2,500 mAh battery. The Lumia 640 XL has a 5.7-inch display, 13 MP rear and 5 MP front cameras and 3,000 mAh battery. Meanwhile, Microsoft Director of business sales and operator channels, Nikhil Mathur said: "It is a little premature, but each operator comes with their own requirements. We are, however, in sync with the operators and whenever operator plans rollout we are ready." He was speaking here after launching two new Lumia dual SIM handsets 640 and 640XL. India is among the fastest growing smartphone markets globally. According to market intelligence provider IDC, in the fourth quarter of 2014, smartphone shipments to the country reached roughly 23 million units, up more than four times compared with two years ago. Since Microsoft acquired Nokia's devices business in April 2014, it has continued to position their handsets as budget smartphones. As of December 2014, Windows Phone had the smallest year-on-year increase among the leading operating systems growing just 4.2 per cent, well below the overall market, relying primarily on entry-level Lumia devices to maintain its market position. On online retailing, Mathur said: "The rise of e-commerce in the last few years, and competition have made online retailing very popular. While we will increase our focus here, we will also continue to market our devices strongly offline." Microsoft has also tied up with online wallet Mobikwik and smart cab service, Olacabs, to offer cashback services on recharges.
