Microsoft Lumia owners must be running out of patience with the Windows 10 Mobile update for their handsets not coming despite waiting for months. Reports have claimed several times that the software update would come soon, but it hasn't happened to date.

In what appeared to be authentic, Microsoft Lumia Mexico recently claimed on its Facebook page (via WMPowerUser) that Windows 10 Mobile update would be rolled out to some of its devices on Monday, Feb. 29, but it didn't happen, leaving the Lumia users disappointed.

It was first reported that Microsoft would start seeding the software to its handsets, including Lumia 430, Lumia 532, Lumia 535, Lumia 540 and Lumia 640 in December, but it was not to be. Then reports emerged that the Lumia 535 and Lumia 640 have received the operating system update in Latin America and Poland, which also turned out to be false.

There is no clear word on when the Lumia devices will receive Windows 10 Mobile as Microsoft is yet to announce its update schedule.

However, it may be mentioned that Microsoft had earlier said that it will initially roll out the Windows 10 Mobile update to Lumia 430, Lumia 532, Lumia 535, Lumia 540, Lumia 640, Lumia 640 XL, Lumia 735, Lumia 830 and Lumia 930 before seeding it to the Windows 8.0-based phones.
