Classic BlackBerry devices to stop working

The company first announced the shutdown in September 2020, but reminded users last month that services for the BlackBerry operating system will end Tuesday.

• "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," the company said in a statement.
• In most cases, BlackBerry's Android-based smartphones will continue to function normally.

Be smart: BlackBerry's business has outlived the demise of its devices. It quietly endures as a publicly traded company specializing in enterprise security.
