Whatsapp announced recently that its service will no longer support some old phone in the New Year.
If you have one of these phones, you need to upgrade your handset.
And as of January 1, the software will stop working on BlackBerry OS, BlackBerry 10 and Windows Phone 8.0 and older.
Support for the Nokia S40 will also stop after December 31 next year, while Android versions 2.3.7 and older will cease to function from February 1, 2020.
