After delaying its Windows 10 Mobile rollout - which was originally scheduled to begin in December - Microsoft hasn't yet made any further announcements about when Windows Phone 8.1 device owners can expect to receive the upgrade. But various European network operators have made announcements related to their upgrades in recent days, and the latest is French carrier Bouygues Telecom.
The carrier responded to an enquiry from FraWin.com's Cassim Ketfi, asking when the update would begin rolling out to its customers:
The response states that the update from Windows Phone 8.1 to Windows 10 will begin next week, and in a further tweet, it listed the handsets that will be upgraded:
Curiously, the carrier listed two devices - the Lumia 636 and Lumia 638, international variants of the 63x-series sold only in certain markets - that it never officially sold or supported.
But notably absent from that list are various Windows Phones with older Snapdragon processors, such as the Lumia 520 and Lumia 1020; all of the devices that the carrier has said will be upgraded are those with newer Snapdragon 200, 400 and 800 chips. HTC said this week that it has no plans to upgrade its Windows Phone 8X, which has an older Snapdragon S4 Plus processor - the same as that used in devices like the Lumia 920 and 1020.
While Bouygues Telecom did not reveal the exact date on which it will begin rolling out Windows 10 Mobile to the devices that it listed, its customers clearly don't have too much longer to wait.
