This is not the first time that WhatsApp is ending support for old mobile platforms.
Confirming this bad news in a post over its official blog, the Facebook-owned company has stated that it will pull the plug on several mobile platforms that include BlackBerry OS, BlackBerry 10, Windows Phone 8.0 and some older platforms from December 31, 2017.
This means that users with smartphones running on OSes named by WhatsApp should consider upgrading to new phones to access the instant messaging app properly.
WhatsApp's end-of-life date on some other platforms won't be arriving as quickly.
"We will no longer actively develop for these platforms, some features may stop functioning at any time", WhatsApp said.
Once you have one of these devices, simply install WhatsApp and verify your phone number on the new device.
There is now no option to transfer your chat history between platforms.
WhatsApp announced a year ago that it will stop supporting some mobile platforms that don't offer the kind of capabilities the company needs to expand the app's features. Earlier this month, BlackBerry shared that BB10 will be supported for "at least two" more years.
WhatsApp previous year announced it would stop running on a variety of models, including iPhones, Android phones and Windows phones. These included Android 2.1 and Android 2.2; Windows Phone 7 and Android 2.1 and Android 2.2; and Windows Phone 7.
As for Nokia, WhatsApp has also shared that support for the Nokia S40 will be dropped on December 31, 2018.
As per the company's press note, WhatsApp service will be severed to Nokia S40-powered phones after December 18, 2018, and the Android v2.3.7 Gingerbread-based devices will lose the messenger app support after February 1, 2020.
