Bottom line: BlackBerry announced this week that it will stop support for legacy services running its operating system in the next few days. Functionality that simply won’t be there anymore includes basic things like making phone calls and text messaging, effectively ending the life of older BlackBerry phones (all models not running Android) as communication devices.
The original announcement that BlackBerry was ending legacy OS support came in September 2020. This week the company issued a reminder along with an extensive FAQ outlining what users should do. On January 4, legacy services for BlackBerry 7.1 OS and earlier, BlackBerry 10 software, BlackBerry PlayBook OS 2.1 and earlier, will end.
Devices running those operating systems, which the FAQ lists, won’t be able to make calls, send texts, or even dial 9-1-1 over cellular or Wi-Fi.
