WhatsApp won’t be supported on devices running BlackBerry OS, BlackBerry 10 and Windows Phone 8.0 as from December 31, 2017. We saw a post on a blog with the End of Life date clearly states that users of BlackBerry OS, BlackBerry 10 and Windows Phone 8.0 and older operating systems will not be able to use the app after December 31, 2017 which isn’t far from now
Don’t forget WhatsApp extended support for the platforms in June this year. At that time, WhatsApp also found that the application would stop working on NokiaS40 phones will be stopped from December 31, 2018. The application will stop working on Android 2.3.7 and older phones (Gingerbread) will be stopped from February 1, 2020. Messaging applications have become unavailable on Nokia phones running Symbian S60 since June 30, 2017.
Consider upgrading to a newer phone so you can access WhatsApp. WhatsApp updates for other versions of the operating system, such as Windows Phone 7, Android 2.1, Android 2.2, and iOS 6, were halted in 2016.
WhatsApp has officially redeemed its new standalone business application this month, which includes verified and unverified profiles. This gives businesses a formal way to do business through messaging apps.
