Do you still have an old BlackBerry phone sitting at the bottom of your drawer somewhere? Well it’s about to officially become a paperweight.

Starting on Jan. 4 the devices running on BlackBerry’s legacy operating systems and software “will no longer reliably function,” the company said in a news release.

“As another milestone in the BlackBerry journey, we will be taking steps to decommission the legacy services for BlackBerry 7.1 OS and earlier, BlackBerry 10 software, BlackBerry PlayBook OS 2.1 and earlier versions, with an end of life or termination date of January 4, 2022. As of this date, devices running these legacy services and software through either carrier or Wi-Fi connections will no longer reliably function, including for data, phone calls, SMS and 9-1-1 functionality. We have chosen to extend our service until then as an expression of thanks to our loyal partners and customers,” the company said.

This comes as part of the company’s efforts to focus on providing security software and services to enterprises and governments around the world under the name BlackBerry Limited.
