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 termination of these service offerings and infrastructure will also impact functionality for applications such as Enhanced Sim Based Licensing (ESBL) / Identity Based Licensing (IBL), BlackBerry hosted email addresses, BlackBerry Link, BlackBerry Desktop Manager, BlackBerry Blend, BlackBerry Protect (allows consumers to lock, locate or wipe BBOS, BlackBerry 10 devices remotely).
There is no impact to the new BlackBerry Protect which is an AI-based endpoint security solution.
- What services will be terminated and what will be impacted?
At the time of termination of services, devices running BlackBerry 7.1 OS and earlier software, BlackBerry 10 software, and BlackBerry PlayBook OS 2.1 and earlier software through either carrier or Wi-Fi connections will no longer reliably function. These devices will lack the ability to receive over the air provisioning updates and as such, this functionality will no longer be expected to reliably function, including for data, phone calls, SMS and 9-1-1 functionality. Applications (BlackBerry Link, BlackBerry Desktop Manager, and BlackBerry Blend) will also have limited functionality.
