Microsoft Mobile
A Finnish Microsoft subsidiary that developed and manufactured Lumia smartphones, Nokia-branded feature phones, and other mobile devices from 2014 until Microsoft withdrew from the phone business.

Overview
Microsoft Mobile Oy was the Finnish subsidiary created when Microsoft completed its acquisition of Nokia's Devices and Services business on 25 April 2014. Based in Keilaniemi, Espoo, the subsidiary inherited Nokia's mobile-phone manufacturing operations, device brands, engineering resources, patents, and product pipeline. Its creation represented the operational culmination of the Microsoft–Nokia partnership announced in 2011 and of Steve Ballmer's strategy to make Microsoft a devices-and-services company rather than a software supplier alone. The business had its roots in Nokia's decision to make Windows Phone the exclusive operating system for its principal smartphone range. Under chief executive Stephen Elop, Nokia introduced the Lumia family, which became the leading source of Windows Phone hardware and achieved particular traction in lower-priced and mid-range products and in several emerging markets. The alliance also connected Nokia hardware with Microsoft's services, including Bing, while Nokia's mapping data and services were incorporated into Microsoft's mapping offering. Although Lumia was the strongest Windows Phone product family, Nokia's wider handset business was already under severe pressure from Apple's iPhone and the rapidly expanding Android ecosystem. Windows Phone's limited market share and comparatively small application catalog restricted the ability of Nokia and Microsoft to compete at scale. Microsoft announced in September 2013 that it would acquire Nokia's devices and services operations for €3.79 billion and separately license Nokia's patent portfolio for €1.65 billion over ten years. The combined transaction, valued at slightly more than €5.4 billion, closed after regulatory delays in April 2014. Microsoft received the Lumia and Asha brands, a license to use the Nokia name on feature phones, design-related patents, and access to a large portfolio of utility patents. Elop joined Microsoft as executive vice president responsible for the Devices group, which also covered products beyond phones. After the acquisition, Microsoft gradually shifted the consumer-facing identity from Nokia toward Microsoft Lumia. Some 2014 products, including the Lumia 830 and Lumia 735, still carried Nokia branding, but later smartphones increasingly used Microsoft branding. The company continued to develop Windows Phone and then Windows 10 Mobile products, including the Lumia 950 and Lumia 950 XL. It also discontinued or deprioritized several inherited product lines, including Asha, Series 40, and Nokia X, as it concentrated resources on Windows-based smartphones and Microsoft's broader device strategy. The strategy did not reverse the platform's declining position. Microsoft announced a US$7.8 billion write-down associated primarily with the Nokia phone acquisition in 2015 and disclosed substantial workforce reductions, with the phone business bearing much of the impact. In May 2016, Microsoft sold the feature-phone business and rights to use the Nokia brand for those products to HMD Global and Foxconn-linked manufacturing interests. Microsoft also announced further reductions in Finland and said it would focus on productivity and software services across competing mobile platforms rather than continue as a conventional smartphone manufacturer. Microsoft Mobile therefore became a transitional organization rather than a lasting consumer-phone brand. Microsoft retained Windows 10 Mobile support for existing devices for a period, but did not build a sustainable successor product portfolio. In 2017, executive Joe Belfiore publicly confirmed that Microsoft had stopped developing new Windows phones and new Windows 10 Mobile features because of weak market share and the difficulty of attracting application developers. The Microsoft Mobile operating business is consequently regarded as defunct, although Microsoft continues to offer mobile applications and services for Android and iOS and later returned to hardware through…
History
Microsoft Mobile was established through Microsoft's acquisition of Nokia's Devices and Services division. The relationship began in February 2011, when Microsoft and Nokia announced that Nokia would make Windows Phone its main smartphone platform. The companies combined Nokia hardware and distribution with Microsoft's operating system and services. Bing was used on Nokia products, while Nokia mapping assets supported Microsoft's mapping services. Nokia's first major Windows Phone products were the Lumia 800 and Lumia 710, introduced in October 2011. The partnership gave Windows Phone its most important hardware manufacturer, but it did not solve the platform's structural disadvantages. Nokia's smartphone position fell rapidly as Android manufacturers expanded across price points and Apple strengthened the premium segment. Lumia sales grew and periodically outperformed rival Windows Phone vendors, especially in affordable devices, but the wider Nokia handset business suffered falling revenue, plant closures, layoffs, and repeated operating losses. Windows Phone also remained far behind Android and iOS in application availability and global scale. Microsoft announced the Nokia acquisition on 2 September 2013. The transaction consisted of €3.79 billion for the devices and services business and €1.65 billion for a ten-year patent license, for a total of more than €5.4 billion. It closed on 25 April 2014 and created Microsoft Mobile Oy in Finland. Microsoft acquired the Lumia and Asha brands, licenses for selected Nokia trademarks, design patents, and access to Nokia's utility-patent portfolio. Stephen Elop moved to Microsoft to lead the Devices group, while Nokia appointed Risto Siilasmaa as interim chief executive before Rajeev Suri became chief executive of the remaining Nokia company. The new subsidiary inherited Lumia smartphones, Asha and Series 40 feature phones, and other development programs. Microsoft soon narrowed the portfolio. Nokia Mail and Nokia Chat were closed with migration paths to Outlook.com and Skype, while online communities and applications were rebranded around Microsoft Lumia. Several 2014 devices retained Nokia branding, but Microsoft increasingly presented Lumia as its own device family. It cancelled or ended future development of Asha, Series 40, and Nokia X products, concentrating on Windows Phone. Microsoft launched Lumia devices based on Windows Phone 8.1 and later Windows 10 Mobile. The Lumia 950 and Lumia 950 XL represented the company's high-end Windows 10 Mobile effort, while lower-cost Lumia phones continued to target price-sensitive markets. The portfolio could not generate enough volume or developer momentum. In 2015 Microsoft announced an approximately US$7.8 billion write-down connected chiefly with the Nokia phone acquisition and reduced its phone workforce substantially. In May 2016, Microsoft announced the sale of its feature-phone business and Nokia brand rights for feature phones to HMD Global and Foxconn-linked entities. It also announced further job cuts in Finland and a strategic shift toward productivity applications and services on Android and iOS. Microsoft did not immediately end support for existing Windows 10 Mobile devices, but its hardware investment became increasingly limited. In 2017 Joe Belfiore stated that the company had stopped developing new Windows phones and new Windows 10 Mobile features. Microsoft Mobile consequently ceased to operate as a meaningful phone manufacturer, while Microsoft continued its mobile presence through software, cloud services, and applications on competing platforms.

Products and positioning
A vertically integrated Microsoft mobile-device business built around Windows Phone and Windows 10 Mobile, combining Nokia's hardware, manufacturing, design, and distribution capabilities with Microsoft's software and services. Its products emphasized integration with Microsoft accounts and services, camera technology, mapping, and affordable Lumia devices, but the business ultimately struggled against Android and iOS.
LumiaSmartphone family2011
Lumia was the principal smartphone family associated first with Nokia and then with Microsoft Mobile. It covered entry-level, mid-range, and premium Windows Phone devices, with later models upgraded toward Windows 10 Mobile. The range was known for colorful industrial design, camera-focused models, integration with Microsoft services, and broad availability in emerging markets. Microsoft inherited the brand in 2014 and used it during the transition from Nokia identity to Microsoft Lumia. The Lumia 950 and 950 XL were the final prominent high-end Microsoft-branded Windows 10 Mobile phones.
AshaFeature phone and low-cost smart-device family2011
Asha was Nokia's low-cost mobile-device family, inherited by Microsoft through the acquisition. It served price-sensitive customers with feature-phone and simplified smartphone functionality, including access to selected online services. Microsoft discontinued future development of the Asha line after the acquisition as it narrowed its mobile strategy around Windows Phone and later Windows 10 Mobile.
Nokia-branded feature phonesFeature phones2014
Microsoft Mobile continued selling feature phones under a ten-year license for the Nokia name. These products used the S30 or S30+ platform and served markets where basic calling, messaging, long battery life, and low purchase prices remained important. Microsoft ultimately sold the feature-phone business and relevant Nokia trademark rights in 2016, ending its direct role in this product category.
Lumia 950 and Lumia 950 XLWindows 10 Mobile smartphones2015
The Lumia 950 and Lumia 950 XL were Microsoft Mobile's flagship Windows 10 Mobile smartphones. They represented Microsoft's attempt to provide high-end hardware aligned with the Windows 10 common-platform strategy and Microsoft's productivity ecosystem. Their release demonstrated the company's continuing device ambitions, but they arrived as Windows phone market share and developer support were already weakening.
Microsoft BandWearable device2014
Microsoft Band was a wearable-device program selected as an alternative to Nokia's Moonraker smartwatch prototype after the acquisition. It reflected Microsoft's broader interest in health, fitness, and cross-platform mobile experiences, but it was not a Microsoft Mobile phone product and did not become a successor to the inherited Nokia hardware portfolio.
