Microsoft is planning to end support for the Windows phone it once championed as a potential iPhone, BlackBerry and Galaxy killer.

On Friday, the tech giant announced that anyone who still uses its Windows 10 mobile platform — once called Windows Phone — should switch over to an iPhone or an Android phone. A change to the Windows 10 Mobile support page was first spotted by Thurrott, a site that covers Microsoft.

Microsoft said that on Dec. 10, 2019, it will stop sending "new security updates, non-security hotfixes, free assisted support options, or technical content updates from Microsoft for free." In other words, there aren't going to be any more updates, and only a few phone models will even be supported until that final date.

"With the Windows 10 Mobile OS end of support, we recommend that customers move to a supported Android or iOS device," Microsoft said. "Microsoft's mission statement to empower every person and every organization on the planet to achieve more, compels us to support our Mobile apps on those platforms and devices."
