In May 2013, Nokia released the Asha platform for its low-end smartphone devices. The Verge commented that this might have been recognition on the part of Nokia that Windows Phones weren't selling at the bottom end of the smartphone market fast enough and that they might be "hedging their commitment" to the Windows Phone platform.[39] In the same month, Nokia announced its partnership with the world's largest cellular operator, China Mobile, to offer Nokia's new Windows-based phone, the Lumia 920, as the Lumia 920T, an exclusive Chinese variant.
