At the Mobile World Congress 2015, Microsoft introduced Lumia 640 and Lumia 640 XL, two new smartphones that give people greater flexibility and freedom to choose when and where they get things done.
Both phones are upgradeable to Windows 10, which offers more personal computing and greater productivity, and will be available later this year.

In a competitive marketplace, Microsoft continues to deliver innovative smartphone experiences at all price points. Both devices offer the seamless integration of hardware essentials — with a choice of screen sizes and camera capabilities — and Microsoft services to offer incredible productivity with affordability.

With Lumia 640 and Lumia 640 XL, people are prepared for anything — for work, at home and on the go:
* Smoothly and quickly access important documents or run popular websites, apps and games thanks to the 1Gb of onboard memory and powerful Qualcomm ® Snapdragon ™ processor featuring quad-core CPU running at 1.2GHz.
* Enjoy photos and videos on a crisp high-definition (HD) display — either 5 inches on Lumia 640 or 5.7 inches on Lumia 640 XL.
* Power through the day with battery to spare with a long-lasting battery — 2500 mAh for Lumia 640 and 3000 mAh for Lumia 640 XL.
* Capture detail-rich photos even in low light with the 8MP camera on Lumia 640 or 13MP ZEISS optics on Lumia 640 XL. Both feature LED flash, a front-facing camera for Skype video calling, and Lumia Camera software right out of the box.
* Enjoy the latest version of Windows Phone 8.1 and the Lumia Denim update, complete with one-swipe Action Centre, Word Flow and Live Folders. People can also upgrade Lumia 640 and 640 XL to Windows 10 and enjoy its benefits as it becomes available later this year.
* Have the best of both worlds with LTE support available on dual-SIM models for the first time. In addition, all dual-SIM models will feature Smart Dual SIM to help ensure people never miss a call.

Lumia 640 and Lumia 640 XL customers will be able to access new Windows 10 features and innovation through the Windows Insider Program, as well as upgrade to Windows 10 later this year. Key features and improvements of Windows 10 include new universal apps such as Office, Mail and Calendar, and Photos; Internet Protocol-based messaging from Skype and others integrated directly into the messaging experience; an entirely new browsing experience with the new Project Spartan browser; and extended integration of the Cortana personal assistant.
