The Microsoft Lumia 640^[4] and Microsoft Lumia 640 XL^[5] are Windows Phone smartphones developed by Microsoft Mobile. Released on March 2, 2015, the phones are successors to the Nokia Lumia 630 series, released in 2014. The phones are primarily aimed at developing markets,^[6] although they are also available in developed markets as lower-cost options compared to other phones in their classes. The two devices became available in the US and most other markets in June 2015.^[7]

On February 15th 2016, Microsoft announced the Lumia 650, the Lumia 640 successor, with improvements like device encryption, AMOLED display and 16 GB of flash storage.^[1]

Release and availability

The Lumia 640 and 640 XL were unveiled at Microsoft's event at the Mobile World Congress in Barcelona, Spain on March 2, 2015.^[6] The smartphones are mid-range (although Microsoft's Scandinavian General Manager Ossi Korpela referred to the Lumia 640/Lumia 640 XL as affordable high-end smartphones).

The Lumia 640 LTE has U.S. pricing beginning at US$79.99, while the Lumia 640 XL LTE (exclusive to AT&T in the country) is priced at US$249.99.
